The Linux Kernel, the operating system core itself. Security Fixes: In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Prevent use after free on completion memory On driver unload any pending descriptors are flushed at the time the interrupt is freed:...

The vulnerability of the idxd component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the idxd component in the Linux operating system’s kernel is related to a failure during the execution of workqueue. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: dmaengine: idxd: Fix possible Use-After-Free in irq_process_work_list

A vulnerability was found in the Linux kernel's DMA engine component in the irqprocessworklist function. A possible use-after-free condition can occur during list iteration, which is because a descriptor may be freed while another thread is reusing it, potentially leading to access to freed memor...
