Deskripsi CVE
In the Linux kernel, the following vulnerability has been resolved:
time/namespace: Validate nanosecond field in proc_timens_set_offset()
The function validates tv_sec to be within [-KTIME_SEC_MAX, KTIME_SEC_MAX]
but never validates that tv_nsec is within the valid range of
[0, NSEC_PER_SEC-1] before using it in timespec64_add().
timespec64_add() expects both timespec64 structures to have normalized
values with tv_nsec in the range [0, 999999999]. If off->val.tv_nsec
contains invalid values (negative or >= NSEC_PER_SEC), it could lead to
incorrect calculations or unexpected behavior.
Add validation to ensure tv_nsec is within the valid range before
performing the addition.
