CVE-2026-23106

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