RHSA-2026:82939 PUBLISHED CVSS 7.599999904632568 HIGH

A flaw was found in libpcap. The Berkeley Packet Filter (BPF) interpreter in libpcap does not properly validate register indexes in BPF instructions. A local attacker could craft a malicious filter program to trigger an out-of-bounds read and write vulnerability. This could allow the attacker to read and write arbitrary operating system process memory, potentially leading to information disclosure or arbitrary code execution.
