Detailsinfo

A vulnerability was found in Linux Kernel up to 6.0.2 and classified as critical. This issue affects the function device_init_td0_ring of the component staging. The manipulation with an unknown input leads to a memory leak vulnerability. Using CWE to declare the problem leads to CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. Impacted is availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: staging: vt6655: fix potential memory leak In function device_init_td0_ring, memory is allocated for member td_info of priv->apTD0Rings[i], with i increasing from 0. In case of allocation failure, the memory is freed in reversed order, with i decreasing to 0. However, the case i=0 is left out and thus memory is leaked. Modify the memory freeing loop to include the case i=0.

It is possible to read the advisory at git.kernel.org. The identification of this vulnerability is CVE-2022-50758 since 12/24/2025. Technical details of the vulnerability are known, but there is no available exploit.
