Echo: linux: security update to 6.4.4-1

medium Tenable Self-Hosted Container Security Plugin ID 459196

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: start_kernel: Add __no_stack_protector
 function attribute Back during the discussion of commit a9a3ed1eff36 ("x86: Fix early boot crash on
 gcc-10, third try") we discussed the need for a function attribute to control the omission of stack
 protectors on a per-function basis; at the time Clang had support for no_stack_protector but GCC did not.
 This was fixed in gcc-11. Now that the function attribute is available, let's start using it. Callers of
 boot_init_stack_canary need to use this function attribute unless they're compiled with -fno-stack-
 protector, otherwise the canary stored in the stack slot of the caller will differ upon the call to
 boot_init_stack_canary. This will lead to a call to __stack_chk_fail() then panic. (CVE-2023-53491)

Solution

Update the linux library and its related packages to version 6.4.4-1 or later.
