Ubuntu.comUB:CVE-2021-47348CVE-2021-47348
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Avoid HDCP over-read and corruption Instead of reading the
desired 5 bytes of the actual target field, the code was reading 8. This
could result in a corrupted value if the trailing 3 bytes were non-zero, so
instead use an appropriately sized and zero-initialized bounce buffer, and
read only 5 bytes before casting to u64.
