CVE-2023-53371 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix memory leak in mlx5e_fs_tt_redirect_any_create The memory pointed to by the fs->any pointer is not freed in the error path of mlx5e_fs_tt_redirect_any_create, which can lead to a memory leak. Fix by freeing the memory in the error path, thereby making the error path identical to mlx5e_fs_tt_redirect_any_destroy().
A memory leak vulnerability has been identified in the Linux kernel's mlx5e flow steering component. The issue arises in the 'mlx5e_fs_tt_redirect_any_create' function, where the memory allocated to the 'fs->any' pointer is not properly freed in the event of an error. This oversight can lead to a memory leak. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed in upstream commits 3250affdc658557a41df9c5fb567723e421f8bf2 and 75df2fe6d160e16be880aacacd521b135d7177c9. Users can apply the patch available in these commits to fix the memory leak issue.
