CVE-2026-53036

The CVE-2026-53036 issue concerns the Linux kernel BPF JIT on ARM64. check_imm(bits, imm) erroneously allowed a signed N-bit range of [-2^N, 2^N), effectively giving an (N+1)-bit range, which permits values in [2^18, 2^19) for imm19 (and similarly for imm26) to slip through. This caused potential...
