medium Tenable Self-Hosted Container Security Plugin ID 469694

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: ipvs: do not keep dest_dst if dev is
going down There is race between the netdev notifier ip_vs_dst_event() and the code that caches dst with
dev that is going down. As the FIB can be notified for the closed device after our handler finishes, it is
possible valid route to be returned and cached resuling in a leaked dev reference until the dest is not
removed. To prevent new dest_dst to be attached to dest just after the handler dropped the old one, add a
netif_running() check to make sure the notifier handler is not currently running for device that is
closing. (CVE-2026-45917)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.0.140 or later.
