CVE-2025-38339

CVE-2025-38339: Linux kernel powerpc/bpf trampoline JIT size calculation could overflow when arch_bpf_trampoline_size() estimates size before allocation. The dummy pass size may differ from actual JIT needs, causing a WARN_ON_ONCE overflow check in arch/powerpc/net/bpf_jit_comp.c. The fix account...
