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...

ALPINE-CVE-2026-31911

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...

ALPINE-CVE-2026-6244

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-2026-31912

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...

AZL-99729 CVE-2026-18238 affecting package libpcap for versions less than 1.10.7-1

The rpcap client code that processes a RPCAPMSGPACKET message received from the server incorrectly validates its headers. A malicious server can send a crafted message and cause the client to treat up to 20 bytes of the client process memory beyond the end of the buffer as if it was a part of the...

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...
