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 concerns the Linux kernel DRM MSM A6XX driver. The issue arises in a6xx_get_gmu_registers() where three sets of GMU registers are read but the allocation for the array wasn’t updated, triggering a KASAN slab-out-of-bounds write (Write of size 8) in _a6xx_get_gmu_registers. Public n...

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...
