PT-2025-49448

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists where an interrupt request IRQ work item can be queued in the bpf ringbuf commit function, but the ring buffer may be freed before the work item executes. This ca...

EUVD-2023-60021

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix integer overflow in amdgpucspass1 The type of size is unsigned int, if size is 0x40000000, there will be an integer overflow, size will be zero after size = sizeofuint32t, will cause uninitialized memory to be...

CVE-2023-53587

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Sync IRQ works before buffer destruction If something was written to the buffer just before destruction, it may be possible maybe not in a real system, but it did happen in ARCH=um with time-travel to destroy the...

PT-2025-40750

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.3.0-rc1 Description The Linux kernel contained a flaw in the ring buffer implementation where an interrupt request IRQ work could run after the buffer it operated on was destroyed. This could lead to a...

AZL-73947 CVE-2025-39749 affecting package kernel for versions less than 5.15.200.1-1

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

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...

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-2025-39744

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...
