CVE-2026-80927

Not enough EPSS history yet.

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.
