  • Feb 4, 2026In the Linux kernel, the following vulnerability has been resolved: timekeeping: Adjust the leap state for the correct auxiliary timekeeper When __do_ajdtimexCVE-2026-23106 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67Medium 5.5

    In the Linux kernel, the following vulnerability has been resolved: timekeeping: Adjust the leap state for the correct auxiliary timekeeper When __do_ajdtimex() was introduced to handle adjtimex for any timekeeper, this reference to tk_core was not updated. When called on an auxiliary timekeeper, the core timekeeper would be updated incorrectly. This gets caught by the lock debugging diagnostics because the timekeepers sequence lock gets written to without holding its associated spinlock: WARNING: include/linux/seqlock.h:226 at __do_adjtimex+0x394/0x3b0, CPU#2: test/125 aux_clock_adj (kernel/time/timekeeping.c:2979) __do_sys_clock_adjtime (kernel/time/posix-timers.c:1161 kernel/time/posix-timers.c:1173) do_syscall_64 (arch/x86/entry/syscall_64.c:63 (discriminator 1) arch/x86/entry/syscall_64.c:94 (discriminator 1)) entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:131) Update the correct auxiliary timekeeper.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
