CVE-2026-6554

libpcap versions before 1.10.7 contain an infinite loop vulnerability in its BPF interpreter . The 'ja L' instruction uses a signed offset to implement backward-jump loops, but the interpreter does not cap the number of loop iterations. In particular uncommon use cases, a crafted filter program c...

CVE-2026-6244

libpcap versions before 1.10.7 contain a division by zero flaw in the BPF interpreter. The div #k and mod #k ALU instructions do not check whether the immediate value is zero, allowing a crafted filter program to trigger a divide-by-zero in uncommon use cases. The vulnerability is locally exploit...

CVE-2026-31911

libpcap (the packet capture library used by tcpdump) contains a vulnerability in its BPF interpreter that calls abort() upon encountering a BPF instruction with an invalid opcode. In uncommon use cases, a crafted filter program can cause the host OS process to terminate, resulting in a local deni...

EUVD-2026-72016

libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program can cause the...

CVE-2026-31912

libpcap before 1.10.7 contains an out-of-bounds read in its BPF interpreter . The interpreter fails to detect two conditions: reaching the end of the filter program buffer due to a missing return instruction, and executing a jump instruction whose offset translates to a pointer outside the buffer...

CVE-2026-0799

libpcap versions before 1.10.7 contain an out-of-bounds read and write (OOBR/OOBW) in its BPF interpreter. In BPF instructions that load/store a value from/to a scratch memory register, the register index is an unsigned 32-bit integer that must not exceed 15, but the interpreter does not validate...
