CVE-2026-93146 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by RHEL.
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.
