Technical description

LcpDecodeConfig() did not validate the length of received endpoint discriminator options against the minimum required by RFC 1717. Undersized options would trigger an out-of-bounds write. A malicious PPP peer can exploit CVE-2026-58095 and CVE-2026-58096 to crash ppp(8) or potentially execute arbitrary code as root.
