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...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the improper handling of offsets in the BPF interpreter, specifically in the ja L instruction. An attacker can cause the process to enter an infinite loop by supplying a specially crafted filter program. Remediatio...

CVE-2026-6554: Loop with Unreachable Exit Condition
