VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)
Description A NULL pointer dereference issue has been identified in the Linux kernel's MLX5 network driver. The problem arises in the mlx5 chains create table() function, where the return values of mlx5 get fdb sub ns() and mlx5 get flow namespace() are not properly checked. If either function fails, it can lead to a NULL pointer dereference. To prevent this, the function should log an error message using mlx5 core warn() and return an error pointer.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
