CVE-2026-68162
CVE-2026-68162 is a Linux kernel SCTP vulnerability (local) where a Use-After-Free can occur during netns teardown due to an auth_enable sysctl window. The bug stems from SCTP’s per-net sysctl state being registered before the control socket is fully established and remaining writable after inet_...
CVE-2026-68162 sctp: avoid auth_enable sysctl UAF during netns teardown
In the Linux kernel, the following vulnerability has been resolved: sctp: avoid authenable sysctl UAF during netns teardown procsctpdoauth updates the SCTP control socket after changing net.sctp.authenable. The handler gets the per-net SCTP state from ctl-data, so an already opened sysctl file ca...

kernel: sctp: fix to calc the INIT/INIT-ACK chunk length correctly to set
net/sctp/smmakechunk.c in the Linux kernel before 2.6.34, when addipenable and authenable are used, does not consider the amount of zero padding during calculation of chunk lengths for 1 INIT and 2 INIT ACK chunks, which allows remote attackers to cause a denial of service OOPS via crafted packet...
