high Tenable Self-Hosted Container Security Plugin ID 469880

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: time/jiffies: Register jiffies
clocksource before usage Teddy reported that a XEN HVM has a long boot delay, which was bisected to the
recent enhancements to the negative motion detection. It turned out that the jiffies clocksource is used
in early boot before it is registered, which leaves the max_delta_raw field at zero. That causes the read
out to be clamped to the max delta of 0, which means time is not making progress. Cure it by ensuring that
it is initialized before its first usage in timekeeping_init(). (CVE-2026-68092)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.0.28 or later.
