Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved, related to the LoongArch architecture and the Berkeley Packet Filter (BPF). The issue occurs when a subprogram's return value is overridden, causing a panic at the ld.bu instruction. This happens because the return value is sign-extended to the a0 register, which is then propagated back to the a5 register, expecting a zero-extended return value. The problem arises from the difference in handling return values between native calls and BPF-to-BPF calls.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
