This vulnerability is reported as CVE-2022-50326. No exploit exists. Upgrading the affected component is recommended.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.0.2. It has been classified as critical. Affected is an unknown code block of the component media. 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: media: airspy: fix memory leak in airspy probe The commit ca9dc8d06ab6 ("media: airspy: respect the DMA coherency rules") moves variable buf from stack to heap, however, it only frees buf in the error handling code, missing deallocation in the success path. Fix this by freeing buf in the success path since this variable does not have any references in other code.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2022-50326 since 09/15/2025. The technical details are unknown and an exploit is not available.

Upgrading to version 6.0.3 eliminates this vulnerability. Applying the patch f4285dd02b6b2ca3435b65fb62c053dd9408fd71/23bc5eb55f8c9607965c20d9ddcc13cb1ae59568 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
