CVE-2026-89685

CVE-2026-89685 is a clock domain mismatch in the Linux kernel's NFS daemon (nfsd) . The function clients_still_reclaiming() derives its grace-period deadline from nn->boot_time (CLOCK_REALTIME , ~1.7 billion seconds) but compares it against ktime_get_boottime_seconds() (CLOCK_BOOTTIME , second...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.6 contains a security vulnerability. This vulnerability stems from a mismatch in the clock domain within the clientsstillreclaiming function. It involves comparing boottime, which is based on CLOCKREALTIME, with CLOCKBOOTTIME. As a result, the comparison always yields a...
