CVE-2026-18313 on Cyberus Linux 26.05

Aliases: CVE-2026-18313

Packages: libpcap

Status: Plausible

Advisory Information

rpcapd can allocate up to 65536 bytes per each RPCAP_MSG_UPDATEFILTER_REQ or RPCAP_MSG_STARTCAP_REQ 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.
