"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntime/namespace: Validate nanosecond field in proc_timens_set_offset()\n\nThe function validates tv_sec to be within [-KTIME_SEC_MAX, KTIME_SEC_MAX]\nbut never validates that tv_nsec is within the valid range of\n[0, NSEC_PER_SEC-1] before using it in timespec64_add().\n\ntimespec64_add() expects both timespec64 structures to have normalized\nvalues with tv_nsec in the range [0, 999999999]. If off->val.tv_nsec\ncontains invalid values (negative or >= NSEC_PER_SEC), it could lead to\nincorrect calculations or unexpected behavior.\n\nAdd validation to ensure tv_nsec is within the valid range before\nperforming the addition."
