CVE-2026-58096

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 ppp8 or potentially execute arbitra...

CVE-2026-58095

mpEnddisc used incorrect length calculations when formatting endpoint discriminator addresses for display, allowing a received endpoint option to overflow a global result buffer. A malicious PPP peer can crash ppp8 or potentially execute arbitrary code as root...
