CVE-2025-71129

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> LoongArch: BPF: Sign extend kfunc call arguments<br /> <br /> The kfunc calls are native calls so they should follow LoongArch calling<br /> conventions. Sign extend its arguments properly to avoid kernel panic.<br /> This is done by adding a new emit_abi_ext() helper. The emit_abi_ext()<br /> helper performs extension in place meaning a value already store in the<br /> target register (Note: this is different from the existing sign_extend()<br /> helper and thus we can&amp;#39;t reuse it).
