CVE-2026-23383

CVE-2026-23383 affects the Linux kernel’s BPF JIT path on arm64. The root cause was 4-byte alignment in bpf_jit_binary_pack_alloc() causing the JIT buffer’s base to be only 4-byte aligned, which could misalign the 64-bit target field in struct bpf_plt. Consequences include UBSAN misaligned-access...
