An update for kernel is now available for openEuler-22.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1257 Final 1.0 1.0 2024-03-08 Initial 2024-03-08 2024-03-08 openEuler SA Tool V1.0 2024-03-08 kernel security update An update for kernel is now available for openEuler-22.03-LTS-SP1. The Linux Kernel, the operating system core itself. Security Fix(es): A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a crash or other related issues.(CVE-2024-1151) In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix NULL pointer dereference in error path When calling mlxsw_sp_acl_tcam_region_destroy() from an error path after failing to attach the region to an ACL group, we hit a NULL pointer dereference upon 'region->group->tcam' [1]. Fix by retrieving the 'tcam' pointer using mlxsw_sp_acl_to_tcam().
