Summary
In the Linux kernel, the following vulnerability has been resolved:
LoongArch: csum: Fix OoB access in IP checksum code for negative lengths
Commit 69e3a6aa6be2 ("LoongArch: Add checksum optimization for 64-bit
system") would cause an undefined shift and an out-of-bounds read.
Commit 8bd795fedb84 ("arm64: csum: Fix OoB access in IP checksum code
for negative lengths") fixes the same issue on ARM64.
