Input Validation Issue in Linux Kernel sysctl Component

CVE-2026-98434

What is CVE-2026-98434?

A vulnerability has been identified in the Linux kernel's sysctl component stemming from an inadequate range check within the do_proc_int_conv_ms_jiffies_minmax function. This oversight allowed the default checks to be bypassed, which could lead to unexpected behavior when processing integer values associated with time measurement. Proper validation checks are essential to prevent potential exploitation that might occur through misconfigured parameters or erroneous input, leading to unwarranted system states.
