CVE-2026-90195

A flaw was found in the Linux kernel's RISC-V 64-bit RV64 Just-In-Time JIT compiler for Berkeley Packet Filter BPF programs. The RV64 JIT fails to perform proper sign-extension for signed 1-byte and 2-byte kernel function kfunc arguments. This oversight can lead to incorrect processing of data...
