Linux Distros Unpatched Vulnerability : CVE-2026-80984

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net/smc: do not dereference an unset send buffer on the SMC-D teardown path smcclosestreamwait calls smctxpreparedsends from inside its skwaitevent condition, a...

CVE-2026-80984

A flaw was found in the net/smc component of the Linux kernel. When a link group terminates while a socket is waiting in smcclosestreamwait, a NULL pointer dereference can occur during the SMC-D teardown path. This can lead to a system crash, resulting in a Denial of Service DoS...
