PT-2026-78317

To retrieve the previous timer value, the kernel calls realtimer gettime, which obtains the current time for the timer's clock. For a timer using CLOCK TAI this can fail when no TAI offset has been configured, but the error return was not checked, so the uninitialized output buffer was copied to...
