CVE-2026-90195

This Linux kernel vulnerability affects the RISC-V (RV64) BPF JIT compiler . The RV64 ABI requires sign-extension for signed 1-byte and 2-byte kfunc arguments , but the JIT failed to perform this extension. The bug was previously masked by a state-pruning behavior in commit 7ce090afbf72, which in...
