CVE-2025-39749

The CVE-2025-39749 issue is in the Linux kernel’s RCU read-side handling: when IRQ work is used (CONFIG_IRQ_WORK=y) and rcu_read_unlock() runs in an interrupts-disabled region, irq-work can interrupt rcu_read_unlock_special(), creating a data race on the per-CPU defer_qs_iw_pending field. The fix...

CVE-2025-39749 rcu: Protect ->defer_qs_iw_pending from data race

In the Linux kernel, the following vulnerability has been resolved: rcu: Protect -deferqsiwpending from data race On kernels built with CONFIGIRQWORK=y, when rcureadunlock is invoked within an interrupts-disabled region of code 1, it will invoke rcureadunlockspecial, which uses an irq-work handle...

CVE-2025-39744

The CVE-2025-39744 issue affects the Linux kernel and describes a deadlock in rcu_read_unlock() when called during irq_exit() if an IPI is issued. The root cause is an incorrect handling of irq_work state inside rcu_read_unlock_special() triggered by irq_exit(), which can cause a system hang/lock...

CVE-2025-39744 rcu: Fix rcu_read_unlock() deadloop due to IRQ work

In the Linux kernel, the following vulnerability has been resolved: rcu: Fix rcureadunlock deadloop due to IRQ work During rcureadunlockspecial, if this happens during irqexit, we can lockup if an IPI is issued. This is because the IPI itself triggers the irqexit path causing a recursive lock up...
