  3. CVE-2024-57949
In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3-its: Don't enable interrupts in its_irq_set_vcpu_affinity() The following call-chain leads to enabling interrupts in a nested interrupt disabled section: irq_set_vcpu_affinity() irq_get_desc_lock() raw_spin_lock_irqsave() <--- Disable interrupts its_irq_set_vcpu_affinity() guard(raw_spinlock_irq) <--- Enables interrupts when leaving the guard() irq_put_desc_unlock() <--- Warns because interrupts are enabled This was broken in commit b97e8a2f7130, which replaced the original raw_spin_[un]lock() pair with guard(raw_spinlock_irq). Fix the issue by using guard(raw_spinlock). [ tglx: Massaged change log ]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: irqchip/gic-v3-its: No habilitar interrupciones en its_irq_set_vcpu_affinity() La siguiente cadena de llamadas lleva a habilitar interrupciones en una sección de interrupción deshabilitada anidada: irq_set_vcpu_affinity() irq_get_desc_lock() raw_spin_lock_irqsave() &lt;--- Deshabilitar interrupciones its_irq_set_vcpu_affinity() guard(raw_spinlock_irq) &lt;--- Habilita interrupciones al salir de guard() irq_put_desc_unlock() &lt;--- Advierte porque las interrupciones están habilitadas Esto se rompió en el commit b97e8a2f7130, que reemplazó el par original raw_spin_[un]lock() con guard(raw_spinlock_irq). Solucione el problema usando guard(raw_spinlock). [ tglx: Registro de cambios modificado ]
