CVE-2026-6554

Name of the Vulnerable Software and Affected Versions libpcap (affected versions not specified)

Description The BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to enable looping through backward jumps. However, the interpreter does not restrict the number of loop iterations, which allows a specially crafted filter program to trigger an infinite loop in uncommon use cases.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
