kernel: dma: fix call order in dmam_free_coherent

A vulnerability was found in the Linux kernel's dma subsystem in the dmamfreecoherent function where a race condition is possible between the calls to dmamfreecoherent and devresdestroy leading to a double entry in the devres list. This flaw could potentially lead to memory corruption or unexpect...

CVE-2024-43856

CVE-2024-43856 affects the Linux kernel DMA code. The vulnerability occurs in dma/dmam_free_coherent: after freeing a DMA allocation, the code frees the vaddr, then calls devres_destroy() to remove tracking data. A concurrent task could allocate the same vaddr and add it to the devres list betwee...
