An update for kernel is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1797 Final 1.0 1.0 2023-11-10 Initial 2023-11-10 2023-11-10 openEuler SA Tool V1.0 2023-11-10 kernel security update An update for kernel is now available for openEuler-22.03-LTS. The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds and crash in read_descriptors in drivers/usb/core/sysfs.c.(CVE-2023-37453) An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.(CVE-2023-46813) An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur.(CVE-2023-46862) A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation in case that the attacker already has local privileges.(CVE-2023-5178) An update for kernel is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high.
