Upgrade torvalds/linux to version 6.1.191, 6.6.66, 6.12.5 or higher.
Overview
Affected versions of this package are vulnerable to Improper Synchronization in the close_work process. An attacker can cause a kernel panic and system crash by remotely triggering a race condition during SMC connection establishment and link-group termination handling. This is only exploitable if the kernel is configured with panic_on_warn=1.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
