An update for kernel is now available for openEuler-20.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-2256 Final 1.0 1.0 2024-10-18 Initial 2024-10-18 2024-10-18 openEuler SA Tool V1.0 2024-10-18 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP4 The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel, the following vulnerability has been resolved: net: hns3: do not allow call hns3_nic_net_open repeatedly hns3_nic_net_open() is not allowed to called repeatly, but there is no checking for this. When doing device reset and setup tc concurrently, there is a small oppotunity to call hns3_nic_net_open repeatedly, and cause kernel bug by calling napi_enable twice. The calltrace information is like below: [ 3078.222780] ------------[ cut here ]------------ [ 3078.230255] kernel BUG at net/core/dev.c:6991!

Do not try to destroy the workqueue unconditionally in the unlikely event that EFI initialisation fails to avoid dereferencing a NULL pointer.(CVE-2022-48879) In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid dirent corruption As Al reported in link[1]: f2fs_rename() ... if (old_dir != new_dir && !whiteout) f2fs_set_link(old_inode, old_dir_entry, old_dir_page, new_dir); else f2fs_put_page(old_dir_page, 0); You want correct inumber in the ".." link.

Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE.(CVE-2024-35955) In the Linux kernel, the following vulnerability has been resolved: ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. Then, the whole ipv6_del_addr is executed for the given entry. The reference count drops to zero and kfree_rcu is scheduled. 3. ipv6_get_ifaddr continues and tries to increments the reference count (in6_ifa_hold). 4. The rcu is unlocked and the entry is freed. 5. The freed entry is returned. Prevent increasing of the reference count in such case. The name in6_ifa_hold_safe is chosen to mimic the existing fib6_info_hold_safe. [ 41.506330] refcount_t: addition on 0; use-after-free.

The firmware will add buffer release work to the work queue through HFI callbacks as a normal part of decoding. Randomly closing the decoder device from userspace during normal decoding can incur a read after free for inst. Fix it by cancelling the work in vdec_close.(CVE-2024-42313) In the Linux kernel, the following vulnerability has been resolved: leds: trigger: Unregister sysfs attributes before calling deactivate() Triggers which have trigger specific sysfs attributes typically store related data in trigger-data allocated by the activate() callback and freed by the deactivate() callback. Calling device_remove_groups() after calling deactivate() leaves a window where the sysfs attributes show/store functions could be called after deactivation and then operate on the just freed trigger-data. Move the device_remove_groups() call to before deactivate() to close this race window. This also makes the deactivation path properly do things in reverse order of the activation path which calls the activate() callback before calling device_add_groups().(CVE-2024-43830) In the Linux kernel, the following vulnerability has been resolved: memcg: protect concurrent access to mem_cgroup_idr Commit 73f576c04b94 ("mm: memcontrol: fix cgroup creation failure after many small jobs") decoupled the memcg IDs from the CSS ID space to fix the cgroup creation failures. It introduced IDR to maintain the memcg ID space. The IDR depends on external synchronization mechanisms for modifications. For the mem_cgroup_idr, the idr_alloc() and idr_replace() happen within css callback and thus are protected through cgroup_mutex from concurrent modifications. However idr_remove() for mem_cgroup_idr was not protected against concurrency and can be run concurrently for different memcgs when they hit their refcnt to zero. Fix that. We have been seeing list_lru based kernel crashes at a low frequency in our fleet for a long time. These crashes were in different part of list_lru code including list_lru_add(), list_lru_del() and reparenting code. Upon further inspection, it looked like for a given object (dentry and inode), the super_block's list_lru didn't have list_lru_one for the memcg of that object. The initial suspicions were either the object is not allocated through kmem_cache_alloc_lru() or somehow memcg_list_lru_alloc() failed to allocate list_lru_one() for a memcg but returned success. No evidence were found for these cases. Looking more deeply, we started seeing situations where valid memcg's id is not present in mem_cgroup_idr and in some cases multiple valid memcgs have same id and mem_cgroup_idr is pointing to one of them. So, the most reasonable explanation is that these situations can happen due to race between multiple idr_remove() calls or race between idr_alloc()/idr_replace() and idr_remove(). These races are causing multiple memcgs to acquire the same ID and then offlining of one of them would cleanup list_lrus on the system for all of them. Later access from other memcgs to the list_lru cause crashes due to missing list_lru_one.(CVE-2024-43892) In the Linux kernel, the following vulnerability has been resolved: serial: core: check uartclk for zero to avoid divide by zero Calling ioctl TIOCSSERIAL with an invalid baud_base can result in uartclk being zero, which will result in a divide by zero error in uart_get_divisor(). The check for uartclk being zero in uart_set_info() needs to be done before other settings are made as subsequent calls to ioctl TIOCSSERIAL for the same port would be impacted if the uartclk check was done where uartclk gets set.

In do_walk_down() we catch this case and handle it correctly, however we return -EIO, which -EUCLEAN is a more appropriate error code. Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convert that to proper error handling.

Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE. 2024-10-18 CVE-2024-35955 openEuler-20.03-LTS-SP4 Medium 5.5 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H kernel security update 2024-10-18 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2024-2256 In the Linux kernel, the following vulnerability has been resolved: ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. Then, the whole ipv6_del_addr is executed for the given entry. The reference count drops to zero and kfree_rcu is scheduled. 3. ipv6_get_ifaddr continues and tries to increments the reference count (in6_ifa_hold). 4. The rcu is unlocked and the entry is freed. 5. The freed entry is returned. Prevent increasing of the reference count in such case. The name in6_ifa_hold_safe is chosen to mimic the existing fib6_info_hold_safe. [ 41.506330] refcount_t: addition on 0; use-after-free.

This also makes the deactivation path properly do things in reverse order of the activation path which calls the activate() callback before calling device_add_groups(). 2024-10-18 CVE-2024-43830 openEuler-20.03-LTS-SP4 Low 3.9 AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:L kernel security update 2024-10-18 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2024-2256 In the Linux kernel, the following vulnerability has been resolved:memcg: protect concurrent access to mem_cgroup_idrCommit 73f576c04b94 ( mm: memcontrol: fix cgroup creation failure aftermany small jobs ) decoupled the memcg IDs from the CSS ID space to fix thecgroup creation failures. It introduced IDR to maintain the memcg IDspace. The IDR depends on external synchronization mechanisms formodifications. For the mem_cgroup_idr, the idr_alloc() and idr_replace()happen within css callback and thus are protected through cgroup_mutexfrom concurrent modifications. However idr_remove() for mem_cgroup_idrwas not protected against concurrency and can be run concurrently fordifferent memcgs when they hit their refcnt to zero. Fix that.We have been seeing list_lru based kernel crashes at a low frequency inour fleet for a long time. These crashes were in different part oflist_lru code including list_lru_add(), list_lru_del() and reparentingcode. Upon further inspection, it looked like for a given object (dentryand inode), the super_block s list_lru didn t have list_lru_one for thememcg of that object. The initial suspicions were either the object isnot allocated through kmem_cache_alloc_lru() or somehowmemcg_list_lru_alloc() failed to allocate list_lru_one() for a memcg butreturned success. No evidence were found for these cases.Looking more deeply, we started seeing situations where valid memcg s idis not present in mem_cgroup_idr and in some cases multiple valid memcgshave same id and mem_cgroup_idr is pointing to one of them. So, the mostreasonable explanation is that these situations can happen due to racebetween multiple idr_remove() calls or race betweenidr_alloc()/idr_replace() and idr_remove(). These races are causingmultiple memcgs to acquire the same ID and then offlining of one of themwould cleanup list_lrus on the system for all of them. Later access fromother memcgs to the list_lru cause crashes due to missing list_lru_one. 2024-10-18 CVE-2024-43892 openEuler-20.03-LTS-SP4 Medium 4.7 AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H kernel security update 2024-10-18 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2024-2256 In the Linux kernel, the following vulnerability has been resolved:serial: core: check uartclk for zero to avoid divide by zeroCalling ioctl TIOCSSERIAL with an invalid baud_base canresult in uartclk being zero, which will result in adivide by zero error in uart_get_divisor().

In walk_down_proc we also BUG_ON(refs == 0), which could happen if we have extent tree corruption. Change that to return -EUCLEAN. In do_walk_down() we catch this case and handle it correctly, however we return -EIO, which -EUCLEAN is a more appropriate error code. Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convert that to proper error handling. Also adjust the error message so we can actually do something with the information. 2024-10-18 CVE-2024-46840 openEuler-20.03-LTS-SP4 Medium 5.5 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H kernel security update 2024-10-18 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2024-2256 In the Linux kernel, the following vulnerability has been resolved: ASoC: meson: axg-card: fix 'use-after-free' Buffer 'card->dai_link' is reallocated in 'meson_card_reallocate_links()', so move 'pad' pointer initialization after this function when memory is already reallocated.

Not all panasonic laptops have this many SINF array entries, for example the Toughbook CF-18 model only has 10 SINF array entries. So it only supports the AC+DC brightness entries and mute. Check that the SINF array has a minimum size which covers all AC+DC brightness entries and refuse to load if the SINF array is smaller. For higher SINF indexes hide the sysfs attributes when the SINF array does not contain an entry for that attribute, avoiding show()/store() accessing the array out of bounds and add bounds checking to the probe() and resume() code accessing these. 2024-10-18 CVE-2024-46859 openEuler-20.03-LTS-SP4 High 7.8 AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H kernel security update 2024-10-18 https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2024-2256
