CVE-2025-40142

CVE-2025-40142 affects the Linux kernel’s ALSA PCM path. The function snd_pcm_group_lock_irq() acquires a spinlock_t using spin_lock_irq(), which disables interrupts and implicitly affects softirq handling. On PREEMPT_RT, softirqs are preemptible and spin_lock_irq() does not disable them, allowin...
