Echo: linux: security update to 6.4.11-1

medium Tenable Self-Hosted Container Security Plugin ID 462387

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: btrfs: don't check PageError in
 __extent_writepage __extent_writepage currenly sets PageError whenever any error happens, and the also
 checks for PageError to decide if to call error handling. This leads to very unclear responsibility for
 cleaning up on errors. In the VM and generic writeback helpers the basic idea is that once I/O is fired
 off all error handling responsibility is delegated to the end I/O handler. But if that end I/O handler
 sets the PageError bit, and the submitter checks it, the bit could in some cases leak into the submission
 context for fast enough I/O. Fix this by simply not checking PageError and just using the local ret
 variable to check for submission errors. This also fundamentally solves the long problem documented in a
 comment in __extent_writepage by never leaking the error bit into the submission context. (CVE-2023-53429)

Solution

Update the linux library and its related packages to version 6.4.11-1 or later.
