CVE-2022-50355

5.5 MEDIUM
Published: September 17, 2025 Modified: December 10, 2025

Description

In the Linux kernel, the following vulnerability has been resolved: staging: vt6655: fix some erroneous memory clean-up loops In some initialization functions of this driver, memory is allocated with 'i' acting as an index variable and increasing from 0. The commit in "Fixes" introduces some clean-up codes in case of allocation failure, which free memory in reverse order with 'i' decreasing to 0. However, there are some problems: - The case i=0 is left out. Thus memory is leaked. - In case memory allocation fails right from the start, the memory freeing loops will start with i=-1 and invalid memory locations will be accessed. One of these loops has been fixed in commit c8ff91535880 ("staging: vt6655: fix potential memory leak"). Fix the remaining erroneous loops.
