SUSE CVE-2026-46027

In the Linux kernel, the following vulnerability has been resolved: net/smc: avoid early lgr access in smcclcwaitmsg A CLC decline can be received while the handshake is still in an early stage, before the connection has been associated with a link group. The decline handling in smcclcwaitmsg...

CVE-2026-46027

A flaw was found in the Linux kernel's net/smc component. A remote attacker could exploit this by sending a Connection Less Connection CLC decline message during an early handshake stage. This causes the system to attempt to update link-group level synchronization state before it is properly...
