CVE-2026-0799 OOBR and OOBW in libpcap before 1.10.7

In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to tr...

PT-2026-86443

Name of the Vulnerable Software and Affected Versions libpcap affected versions not specified Description The BPF interpreter calls the abort function when it encounters a BPF instruction containing an invalid opcode. This behavior allows a crafted filter program to terminate the operating system...

PT-2026-86445

Name of the Vulnerable Software and Affected Versions libpcap affected versions not specified Description The BPF interpreter fails to verify if the immediate value is zero when processing 'div k' and 'mod k' ALU instructions. This allows a specially crafted filter program to trigger a division b...

CVE-2026-31912: Improper Validation of Specified Index, Position, or Offset in Input

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-2026-31911: Reachable Assertion

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...

CVE-2026-6554: Loop with Unreachable Exit Condition

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: Divide By Zero

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...

CVE-2026-0799: Improper Validation of Array Index

In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to tr...

PT-2026-86446

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...

PT-2026-86444

Name of the Vulnerable Software and Affected Versions libpcap affected versions not specified Description The BPF interpreter fails to detect when the end of the filter program buffer is reached due to a missing return instruction, or when a jump instruction uses an offset that points outside the...
