CVE-2026-23071

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2026-23071
In the Linux kernel, the following vulnerability has been resolved: regmap: Fix race condition in hwspinlock irqsave routine Previously, the address of the shared member '&map->spinlock_flags' was passed directly to 'hwspin_lock_timeout_irqsave'. This creates a race condition where multiple contexts contending for the lock could overwrite the shared flags variable, potentially corrupting the state for the current lock owner. Fix this by using a local stack variable 'flags' to store the IRQ state temporarily.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: regmap: Corrección de condición de carrera en la rutina hwspinlock irqsave Anteriormente, la dirección del miembro compartido '&map->spinlock_flags' se pasaba directamente a 'hwspin_lock_timeout_irqsave'. Esto crea una condición de carrera donde múltiples contextos que compiten por el bloqueo podrían sobrescribir la variable de banderas compartida, potencialmente corrompiendo el estado para el propietario actual del bloqueo. Esto se soluciona usando una variable local de pila 'flags' para almacenar temporalmente el estado IRQ.
