UBUNTU-CVE-2025-40142

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Disable bottom softirqs as part of spinlockirq on PREEMPTRT sndpcmgrouplockirq acquires a spinlockt and disables interrupts via spinlockirq. This also implicitly disables the handling of softirqs such as TIMERSOFTIRQ. ...

CVE-2025-40163

In CVE-2025-40163, concrete details show a Linux kernel fix for sched/deadline: the dl_server must be stopped before a CPU goes offline to avoid a spurious hrtimer warning when a CPU is removed (drmgr -c cpu -r -q 1). The root cause was dl_server hrtimer enqueued near CPU offline, with cpu_presen...

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...
