CVE-2024-23382

Kernel memory corruption via DMA fence use-after-free

Published Aug 5, 2024 · Updated Aug 15, 2024

Use-after-free in Qualcomm graphics kernel firmware allows local users to corrupt kernel memory through a request that creates a DMA fence. The public fix changes kgsl_add_fence_event in kgsl_sync.c, but Qualcomm has not disclosed which object is freed before the function reuses it. Exploitation requires local access to an affected device and no prior privileges or user interaction; the corruption occurs in kernel context.
