CVE-2026-31912

A flaw was found in libpcap. The BPF interpreter in libpcap does not correctly handle crafted filter programs, leading to an out-of-bounds read. A local attacker could provide a specially crafted filter program, causing the interpreter to attempt to read memory outside of its allocated buffer. Th...

AZL-99924 CVE-2026-6554 affecting package nmap 7.95-5

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...

AZL-99747 CVE-2026-6554 affecting package libpcap for versions less than 1.10.7-1

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. A crafted filter program or the 'protochain' primitive used on a crafted network packet can cause the interpret...

AZL-99735 CVE-2026-18313 affecting package libpcap for versions less than 1.10.7-1

rpcapd can allocate up to 65536 bytes per each RPCAPMSGUPDATEFILTERREQ or RPCAPMSGSTARTCAPREQ message received from the client, but it never frees the memory, so it leaks memory even under normal use. A malicious client can cause the server to leak memory substantially faster...

ALPINE-CVE-2026-0799

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...
