CyberRota Analysis
AI-GeneratedThe vulnerability allows unprivileged local users to exploit a flaw in the kernel's handling of POSIX timers using CLOCK_TAI, where uninitialized kernel stack memory may be copied to user space due to a failure in error checking. This could lead to the disclosure of sensitive kernel data, posing a risk to system confidentiality. Organizations using affected systems should prioritize remediation to mitigate potential data leaks.
Original NVD Description
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 userspace. An unprivileged local user can obtain uninitialized kernel stack memory by creating a POSIX timer with CLOCK_TAI and calling timer_settime(2), potentially disclosing sensitive kernel data.
