Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel up to 5.18.12. This vulnerability affects the function sfp_probe. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: net: sfp: fix memory leak in sfp_probe() sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When devm_add_action() fails, sfp is not freed, which leads to a memory leak. We should use devm_add_action_or_reset() instead of devm_add_action().

The advisory is available at git.kernel.org. This vulnerability was named CVE-2022-49619 since 02/26/2025. Technical details are known, but there is no available exploit.
