CVE-2024-36281:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2024-36281 affects the Linux kernel's Mellanox MLX5 network driver implementation. The vulnerability was discovered in the IPsec status rules handling where rxcreate no longer allocates a modifyhdr instance that needs to be cleaned up (Kernel Commit).
Technical details
The vulnerability stems from an incorrect cleanup of IPsec status rules in the MLX5 network driver. The issue occurs when mlx5modifyheaderdealloc is called on an unallocated modifyhdr instance, leading to a NULL pointer dereference. Additionally, a memory leak exists due to improper handling of two rules populated related to status (Kernel Commit).
Impact
When exploited, this vulnerability can cause a kernel NULL pointer dereference, resulting in a system crash (kernel panic) and denial of service condition (SUSE Advisory).
Mitigation and workarounds
The vulnerability has been patched in the Linux kernel by replacing the incorrect cleanup calls with mlx5ipsecrxstatusdestroy to properly handle the status rules deletion. Users should update their systems with the latest kernel version that includes this fix (Ubuntu Notice).
