Echo: linux: security update to 6.11.2-1

medium Tenable Cloud Security Plugin ID 461647

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: bpf, lsm: Add check for BPF LSM return
value A bpf prog returning a positive number attached to file_alloc_security hook makes kernel panic. This
happens because file system can not filter out the positive number returned by the LSM prog using IS_ERR,
and misinterprets this positive number as a file pointer. Given that hook file_alloc_security never
returned positive number before the introduction of BPF LSM, and other BPF LSM hooks may encounter similar
issues, this patch adds LSM return value check in verifier, to ensure no unexpected value is returned.
(CVE-2024-47703)

Solution

Update the linux library and its related packages to version 6.11.2-1 or later.
