CVE-2026-98572

A flaw was found in the Linux kernel's extended Berkeley Packet Filter (eBPF) Just-In-Time (JIT) compiler on 32-bit MIPS systems. An instruction generation error during 64-bit jump comparisons causes negative numeric constants to be incorrectly evaluated against a hardware register instead of the intended values. A local user capable of loading BPF programs can exploit this issue to produce invalid comparison results, potentially bypassing security filters or causing unexpected program execution paths.
