Echo: linux: security update to 6.1.176-1

critical Tenable Cloud Security Plugin ID 462356

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: libceph: Fix potential out-of-bounds
 access in osdmap_decode() When decoding osd_state and osd_weight from an incoming osdmap in
 osdmap_decode(), both are decoded for each osd, i.e., map->max_osd times. The ceph_decode_need() check
 only accounts for sizeof(*map->osd_weight) once. This can potentially result in an out-of-bounds memory
 access if the incoming message is corrupted such that the max_osd value exceeds the actual content of the
 osdmap message. This patch fixes the issue by changing the corresponding part in the ceph_decode_need()
 check to account for map->max_osd*sizeof(*map->osd_weight). (CVE-2026-52958)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
