Chainguard: multiple linux-gcp-6.18-bootc packages: security update to 6.18.38-r2

medium Tenable Self-Hosted Container Security Plugin ID 473065

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: ptp: ocp: fix resource freeing order
 Commit a60fc3294a37 ("ptp: rework ptp_clock_unregister() to disable events") added a call to
 ptp_disable_all_events() which changes the configuration of pins if they support EXTTS events. In
 ptp_ocp_detach() pins resources are freed before ptp_clock_unregister() and it leads to use-after-free
 during driver removal. Fix it by changing the order of free/unregister calls. To avoid irq handler running
 on the other core while ptp device unregistering, call synchronize_irq() after HW is configured to stop
 producing irqs and no irqs are in-flight. (CVE-2026-53222)

Solution

Update the linux-gcp-6.18-bootc library and its related packages to version 6.18.38-r2 or later.
