CVE-2026-68295

In the Linux kernel, LoongArch BPF ALU32 division/modulo results were sign-extended in the JIT, causing upper 32 bits to be set while verifier/interpreter assume zero-extension. The issue arises when signed ALU32 BPF_DIV/BPF_MOD (off=1) produce a negative quotient/remainder, leaving bits 63:32 se...
