Last modified

CVE-2026-58096 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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.. EPSS estimates a 0.55% chance of exploitation in the next 30 days.
