Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: arm64: csum: Fix OoB access in IP
checksum code for negative lengths Although commit c2c24edb1d9c ("arm64: csum: Fix pathological zero-
length calls") added an early return for zero-length input, syzkaller has popped up with an example of a
_negative_ length which causes an undefined shift and an out-of-bounds read: | BUG: KASAN: slab-out-of-
