Linux kernel DMA driver Heap Buffer Overflow DoS

The vulnerability of the irqprocessworklist function in the drivers/dma/idxd/irq.c file of the Linux DMA driver core is related to the reutilization of previously freed memory due to concurrent access to resources. Exploiting this vulnerability could allow an attacker to compromise the...

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...
