A flaw was found in the Linux kernel. Due to a missing range validation check in the sysctl subsystem, configured minimum and maximum limits were not enforced during specific millisecond-to-jiffies conversions. A local user with permission to modify kernel parameters could provide out-of-bounds values, potentially leading to system instability or a Denial of Service (DoS).
