CVE-2026-6554

A flaw was found in libpcap. The Berkeley Packet Filter BPF interpreter incorrectly handles offsets in 'ja L' instructions, allowing backward jumps without limiting loop iterations. A local attacker could provide a specially crafted filter program, leading to an infinite loop and causing a Denial...

UBUNTU-CVE-2026-6554

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...

CVE-2026-6554: Loop with Unreachable Exit Condition

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...
