CVE-2010-1188

no score yetEPSS 3.3%

Use-after-free vulnerability in net/ipv4/tcp_input.c in the Linux kernel 2.6 before 2.6.20, when IPV6_RECVPKTINFO is set on a listening socket, allows remote attackers to cause a denial of service (kernel panic) via a SYN packet while the socket is in a listening (TCP_LISTEN) state, which is not properly handled and causes the skb structure to be freed.

EPSS: 3.3% chance of exploitation in the next 30 days; higher than 88% of CVEs (scores of 2026-10-31)
