Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 5.10.189/5.15.123/6.1.42/6.4.7. Affected is the function _r8712_init_xmit_priv. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: staging: r8712: Fix memory leak in _r8712_init_xmit_priv() In the above mentioned routine, memory is allocated in several places. If the first succeeds and a later one fails, the routine will leak memory. This patch fixes commit 2865d42c78a9 ("staging: r8712u: Add the new driver to the mainline kernel"). A potential memory leak in r8712_xmit_resource_alloc() is also addressed.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2023-54001 since 12/24/2025. There are known technical details, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 279921 (Linux Distros Unpatched Vulnerability : CVE-2023-54001), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.10.190, 5.15.124, 6.1.43 or 6.4.8 eliminates this vulnerability.
