CVE-2026-6554 infinte loop in libpcap before 1.10.7

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-2026-6244 division by zero in libpcap before 1.10.7

libpcap BPF interpreter for the 'div k' and 'mod k' ALU instructions does not check whether the immediate value is zero. In particular uncommon use cases a crafted filter program can cause a division by zero...

Division by zero

Overview Affected versions of this package are vulnerable to Division by zero through the BPF interpreter when processing the div k and mod k ALU instructions without validating if the immediate value is zero. An attacker can cause a division-by-zero error by supplying a specially crafted filter...

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...

CVE-2026-31911 abort() in libpcap before 1.10.7 on an invalid BPF opcode

libpcap BPF interpreter calls abort if it encounters a BPF instruction that has an invalid opcode. In particular uncommon use cases a crafted filter program can terminate the OS process...

Reachable Assertion

Overview Affected versions of this package are vulnerable to Reachable Assertion through the BPF interpreter process. An attacker can cause the termination of the operating system process by supplying a crafted filter program containing an invalid opcode. Remediation A fix was pushed into 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...

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...
