Chainguard: linux-desktop-7.2-bootc: security update to 7.2.7-r0

high Tenable Self-Hosted Container Security Plugin ID 474666

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: ksmbd: safely drain sessions during
 logoff SMB3 multichannel allows requests for one session to run on multiple connections. Wait for all
 channels bound to a session before freeing shared session objects. A deferred byte-range lock remains
 counted as a running request and only wakes when its file closes. Wake blocked locks during the drain
 without unpublishing or modifying their file objects. Synchronous CANCEL requests must invoke their
 cancellation callback to wake pending operations, while CHANGE_NOTIFY completion remains specific to the
 asynchronous path. Serialize session teardown with channel registration and previous-session cleanup, and
 use atomic work-state transitions so LOGOFF, CANCEL, and connection teardown invoke cancellation callbacks
 only once. (CVE-2026-98115)

Solution

Update the linux-desktop-7.2-bootc library and its related packages to version 7.2.7-r0 or later.
