CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's mlx5 driver, specifically in the handling of matcher objects during target resize operations, leading to a memory leak if the resize setup fails. This could potentially result in increased memory consumption and instability in systems utilizing the mlx5 hardware offload capabilities. Organizations using Linux with mlx5 hardware should prioritize addressing this issue to maintain optimal system performance and resource management.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: HWS, fix matcher leak on resize target setup failure hws_bwc_matcher_move() allocates a replacement matcher before setting it as the resize target. If mlx5hws_matcher_resize_set_target() fails, the replacement matcher is not attached anywhere and is leaked. Fix the leak by destroying the replacement matcher before returning from the resize-target failure path. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1.1. An x86_64 allyesconfig build showed no new warnings. As we do not have a mlx5 HWS-capable device to test with, no runtime testing was able to be performed.
