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...

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-2026-6554: 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...

PT-2026-86440

Name of the Vulnerable Software and Affected Versions libpcap versions prior to 1.10.7 Description The BPF interpreter fails to validate the register index when loading or storing values from or to a scratch memory register. While the index is an unsigned 32-bit integer that should not exceed 15,...

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...

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...

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-2026-6244: 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-2026-80865

In the Linux kernel, the following vulnerability has been resolved: bpf: Add missing accessok call to copyusersyms As reported by sashiko we use getuser without prior accessok call on the user space pointer. Adding the missing call for the whole pointer array. Plus removing the err check in the...

CVE-2026-80865

CVE-2026-80865 affects the Linux kernel BPF subsystem , specifically the copy_user_syms function. The root cause is a missing access_ok call before using __get_user on a user-space pointer array, which could allow an invalid user-space pointer to be dereferenced without prior validation. The fix ...
