CVE-2021-47535 drm/msm/a6xx: Allocate enough space for GMU registers

In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Allocate enough space for GMU registers In commit 142639a52a01 "drm/msm/a6xx: fix crashstate capture for A650" we changed a6xxgetgmuregisters to read 3 sets of registers. Unfortunately, we didn't change the memory...

CVE-2021-47535

CVE-2021-47535 refers to a Linux kernel flaw in drm/msm/a6xx where a6xx_get_gmu_registers() now reads 3 GMU register sets but the destination array was not resized, causing a slab-out-of-bounds write (KASAN) on affected ChromeOS 5.4 kernels. The issue can trigger memory corruption during crashsta...

CVE-2021-47532

CVE-2021-47532 concerns a leak in the Linux kernel related to the DRM MSM devfreq OPP reference counter. The vulnerability is described as a local issue in the kernel’s OPP handling that could leak references in the OPP (Operating Performance Point) management path within the drm/msm/devfreq subs...

CVE-2021-47531 drm/msm: Fix mmap to include VM_IO and VM_DONTDUMP

In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix mmap to include VMIO and VMDONTDUMP In commit 510410bfc034 "drm/msm: Implement mmap as GEM object function" we switched to a new/cleaner method of doing things. That's good, but we missed a little bit. Before that...

CVE-2021-47531

Mode C CVE-2021-47531: Linux kernel MSM DRM mmap handling fixed. The issue occurred when switching to the new mmap path (drm/msm: Implement mmap as GEM object function) and skipping the default mmap code. This caused missing VM_FLAGS and page-prot setup, contributing to crashes on ARC++ Chromeboo...

CVE-2021-47530 drm/msm: Fix wait_fence submitqueue leak

In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix waitfence submitqueue leak We weren't dropping the submitqueue reference in all paths. In particular, when the fence has already been signalled. Split out a helper to simplify handling this in the various different...

CVE-2021-47530

CVE-2021-47530: Linux kernel vulnerability in drm/msm where the submitqueue reference leak was not dropped across all paths, notably when the fence had already signaled. The fix (described as extracting a helper to normalize handling across different returns) resolves the leak. Public advisories ...
