Use-after-free in Qualcomm DSP service / Android kernel components
CVE-2024-43047 is a high-severity use-after-free vulnerability affecting closed-source Qualcomm components used by Android, described in multiple sources as residing in the Qualcomm Digital Signal Processor (DSP) service and affecting Android kernel-related components across numerous Qualcomm chipsets. The available context indicates the flaw can be triggered during DSP updates to header buffers involving unused DMA handle file descriptors; if an invalid DMA handle FD matches an FD already in use, a use-after-free condition can occur. Qualcomm also describes the issue at a higher level as memory corruption while maintaining memory maps of HLOS memory. Successful exploitation can corrupt memory and has been reported as exploited in limited, targeted attacks.
