CVE-2022-50355
- Published: 2025-09-17T15:15:34.150
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.
