Echo: linux: security update to 6.12.48-1

medium Tenable Self-Hosted Container Security Plugin ID 462469

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: ceph: fix race condition validating
 r_parent before applying state Add validation to ensure the cached parent directory inode matches the
 directory info in MDS replies. This prevents client-side race conditions where concurrent operations (e.g.
 rename) cause r_parent to become stale between request initiation and reply processing, which could lead
 to applying state changes to incorrect directory inodes. [ idryomov: folded a kerneldoc fixup and a
 follow-up fix from Alex to move CEPH_CAP_PIN reference when r_parent is updated: When the parent directory
 lock is not held, req->r_parent can become stale and is updated to point to the correct inode. However,
 the associated CEPH_CAP_PIN reference was not being adjusted. The CEPH_CAP_PIN is a reference on an inode
 that is tracked for accounting purposes. Moving this pin is important to keep the accounting balanced.
 When the pin was not moved from the old parent to the new one, it created two problems: The reference on
 the old, stale parent was never released, causing a reference leak. A reference for the new parent was
 never acquired, creating the risk of a reference underflow later in ceph_mdsc_release_request(). This
 patch corrects the logic by releasing the pin from the old parent and acquiring it for the new parent when
 r_parent is switched. This ensures reference accounting stays balanced. ] (CVE-2025-39927)
