CVE-2024-40924 drm/i915/dpt: Make DPT object unshrinkable

In the Linux kernel, the following vulnerability has been resolved: drm/i915/dpt: Make DPT object unshrinkable In some scenarios, the DPT object gets shrunk but the actual framebuffer did not and thus its still there on the DPT's vm-boundlist. Then it tries to rewrite the PTEs via a stale CPU...

CVE-2024-40916 drm/exynos: hdmi: report safe 640x480 mode as a fallback when no EDID found

In the Linux kernel, the following vulnerability has been resolved: drm/exynos: hdmi: report safe 640x480 mode as a fallback when no EDID found When reading EDID fails and driver reports no modes available, the DRM core adds an artificial 1024x786 mode to the connector. Unfortunately some variant...

CVE-2024-40916

The CVE-2024-40916 issue concerns the Linux kernel DRM/Exynos HDMI driver. When EDID reading fails and the driver reports no modes, the DRM core previously exposed a 1024x786 mode which some Exynos HDMI variants cannot drive. The fix changes this fallback to a safe 640x480 mode to avoid rendering...

CVE-2024-39505

CVE-2024-39505 relates to the Linux kernel drm/komeda code where komeda_pipeline_get_state() may return an error-valued pointer. The fix requires checking the pointer for negative or NULL values before dereferencing. The vulnerability impact is STATED as potential denial of service or corruption ...

In the Linux kernel, the following vulnerability has been resolved: drm/mst: Fix NULL pointer dereference at drmdpaddpayloadpart2 Why Commit: - commit 5aa1dfcdf0a4 "drm/mst: Refactor the flow for payload allocation/removement" accidently overwrite the commit - commit 54d217406afe "drm: use mgr-de...

CVE-2024-39497 drm/shmem-helper: Fix BUG_ON() on mmap(PROT_WRITE, MAP_PRIVATE)

In the Linux kernel, the following vulnerability has been resolved: drm/shmem-helper: Fix BUGON on mmapPROTWRITE, MAPPRIVATE Lack of check for copy-on-write COW mapping in drmgemshmemmmap allows users to call mmap with PROTWRITE and MAPPRIVATE flag causing a kernel panic due to BUGON in...

CVE-2024-39498

CVE-2024-39498 (Linux kernel) resolves a NULL pointer dereference in the DRM MST path during payload handling. The issue stemmed from an overwrite in a refactored payload allocation/removal flow, which regressed when two commits touched in drm_dp_add_payload_part2 used/modified the state input. T...
