Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: schedext: Fixed unsafe locking in the scxdumpstate function. For kernels built with CONFIGPREEMPTRT=y, the dumplock will be converted to a sleepable spinlock instead of a disable-irq one. This can lead to the following scenarios:...

SUSE CVE-2026-43326

In the Linux kernel, the following vulnerability has been resolved: schedext: Fix SCXKICKWAIT deadlock by deferring wait to balance callback SCXKICKWAIT busy-waits in kickcpusirqworkfn using smpcondloadacquire until the target CPU's kicksync advances. Because the irqwork runs in hardirq context,...

CVE-2026-43326

The CVE-2026-43326 entry documents a Linux kernel sched_ext deadlock vulnerability (SCX_KICK_WAIT) where CPUs busy-waited in kick_cpus_irq_workfn() and could form a cycle, freezing the system. The fix defers the wait to a balance callback by replacing the busy-wait with resched_curr(), forcing th...

PT-2026-38953

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Tegra platform's Power Management Controller PMC during system suspend resume. The generic handle irq function is called from a non-interrupt context, which is...

CVE-2026-43115

In the Linux kernel, the following vulnerability has been resolved: srcu: Use irqwork to start GP in tiny SRCU Tiny SRCU's srcugpstartifneeded directly calls schedulework, which acquires the workqueue pool-lock. This causes a lockdep splat when callsrcu is called with a scheduler lock held, due t...

In the Linux kernel, the following vulnerability has been resolved: perf/core: Fix invalid wait context in ctxschedin Lockdep found a bug in the event scheduling when a pinned event was failed and wakes up the threads in the ring buffer like below. It seems it should not grab a wait-queue lock...

CVE-2025-68333 sched_ext: Fix possible deadlock in the deferred_irq_workfn()

In the Linux kernel, the following vulnerability has been resolved: schedext: Fix possible deadlock in the deferredirqworkfn For PREEMPTRT=y kernels, the deferredirqworkfn is executed in the per-cpu irqwork/ task context and not disable-irq, if the rq returned by containerof is current CPU's rq,...
