medium Tenable Self-Hosted Container Security Plugin ID 475651

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: timekeeping: Check the return value of
tk_get_aux_ts64 in __do_adjtimex() If the auxiliary clock is disabled during tk_get_aux_ts64() but is
enabled before tks->clock_valid is checked, then uninitialized stackdata will be used in the calculations
and indirectly leaked to userspace. The same race window also exists after this change and also for the
core timekeeper. But in these cases the only effect would be incorrect adjustments and this is userspace's
responsibility to avoid this. (CVE-2026-80927)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.106 or later.
