- Summary
- LoongArch: BPF: Sign extend kfunc call arguments
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
LoongArch: BPF: Sign extend kfunc call arguments
The kfunc calls are native calls so they should follow LoongArch calling conventions. Sign extend its arguments properly to avoid kernel panic. This is done by adding a new emitabiext() helper. The emitabiext() helper performs extension in place meaning a value already store in the target register (Note: this is different from the existing sign_extend() helper and thus we can't reuse it).
