CVE-2026-6554 on Cyberus Linux 26.05

Aliases: CVE-2026-6554

Packages: libpcap

Status: Plausible

Advisory Information

libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely.
