CVE-2022-50355

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> staging: vt6655: fix some erroneous memory clean-up loops<br /> <br /> In some initialization functions of this driver, memory is allocated with<br /> &amp;#39;i&amp;#39; acting as an index variable and increasing from 0. The commit in<br /> "Fixes" introduces some clean-up codes in case of allocation failure,<br /> which free memory in reverse order with &amp;#39;i&amp;#39; decreasing to 0. However,<br /> there are some problems:<br /> - The case i=0 is left out. Thus memory is leaked.<br /> - In case memory allocation fails right from the start, the memory<br /> freeing loops will start with i=-1 and invalid memory locations will<br /> be accessed.<br /> <br /> One of these loops has been fixed in commit c8ff91535880 ("staging:<br /> vt6655: fix potential memory leak"). Fix the remaining erroneous loops.
