  3. CVE-2026-23106
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.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: gestión del tiempo: Ajustar el estado de salto para el gestor de tiempo auxiliar correcto Cuando se introdujo __do_ajdtimex() para manejar adjtimex para cualquier gestor de tiempo, esta referencia a tk_core no fue actualizada. Cuando se invocaba en un gestor de tiempo auxiliar, el gestor de tiempo principal se actualizaría incorrectamente. Esto es detectado por los diagnósticos de depuración de bloqueos porque el bloqueo de secuencia de los gestores de tiempo se escribe sin mantener su spinlock asociado: ADVERTENCIA: 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) Actualizar el gestor de tiempo auxiliar correcto.
