Doc Text:
A flaw was found in the Linux kernel. A local attacker with low privileges could exploit a memory leak in the `mlx5e_init_rep_rx` function within the `net/mlx5` module. This vulnerability occurs when memory is not properly released during an error handling path. Successful exploitation could lead to a Denial of Service (DoS) condition, making the system unresponsive.

Description OSIDB Bzimport 2025-12-24 14:10:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: fix potential memory leak in mlx5e_init_rep_rx

The memory pointed to by the priv->rx_res pointer is not freed in the error
path of mlx5e_init_rep_rx, which can lead to a memory leak. Fix by freeing
the memory in the error path, thereby making the error path identical to
mlx5e_cleanup_rep_rx().
