Echo: linux: security update to 6.1.180-1

medium Tenable Cloud Security Plugin ID 465441

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix slab-use-after-
 free in l2cap_connect() Extend a critical section to prevent chan from early freeing. Also make the
 l2cap_connect() return type void. Nothing is using the returned value but it is ugly to return a
 potentially freed pointer. Making it void will help with backports because earlier kernels did use the
 return value. Now the compile will break for kernels where this patch is not a complete fix. Call stack
