Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 6.8.1. This vulnerability affects the function tpg_alloc of the component v4l2-tpg. 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: media: v4l2-tpg: fix some memleaks in tpg_alloc In tpg_alloc, resources should be deallocated in each and every error-handling paths, since they are allocated in for statements. Otherwise there would be memleaks because tpg_free is called only when tpg_alloc return 0.
