CVE-2023-52825

CVE-2023-52825 involves a race condition in the Linux kernel’s DRM/AMDKFD svm code where vram buffer unref (prange->svm_bo) can occur concurrently in mmu callbacks and a post-migrate callback to system RAM. The race may lead to use-after-free if the unref is performed unsafely across async tas...

CVE-2023-52816

CVE-2023-52816 relates to a Linux kernel flaw in drm/amdkfd where a UBSAN shift out-of-bounds occurs when shifting exponent 255, which is too large for a 64-bit unsigned long during a page-fault/get_user path. Impact is high (local exploitability per CVSS), and the issue is fixed by kernel patche...
