In the Linux kernel, the following vulnerability has been resolved: drm/panthor: fix firmware control interface bounds checks panthor_init_cs_iface() and panthor_init_csg_iface() validate firmware control interface offsets with 32-bit arithmetic an...

In the Linux kernel, the following vulnerability has been resolved: drm/panel-edp: fix i2c adapter leak on probe failure Make sure to drop the i2c adapter reference on probe failure (e.g. probe deferral) and on driver unbind also if a devicetree re...

In the Linux kernel, the following vulnerability has been resolved: drm: fix race between partial drm_dev_register() failure and ioctl If drm_dev_register() fails after registering a minor (e.g. render minor registered, primary minor fails), usersp...

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Guard against NULL driver_data in i915_pci_probe() pci_match_device() can return the dummy pci_device_id_any entry when a device is force-bound via sysfs driver_override,...

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: avoid divide-by-zero in __is_lut_linear() __is_lut_linear() computes the expected value of each entry with expected = i * MAX_DRM_LUT_VALUE / (size - 1); If it ...

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix dc_lock leak on GPU reset error paths On GPU reset, dm_suspend() takes dc_lock and leaves it for dm_resume() to drop. If amdgpu_dm_commit_zero_streams() or dm_...

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: validate plane degamma LUT size for private color prop Unlike the CRTC degamma path, which is guarded by amdgpu_dm_verify_lut_sizes(), the per-plane degamma LUT si...

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn: fix integer overflow in dec_msg buffer count check If the supplied msg[2] (num_buffers) is 0x3FFFFFFF, the expression 6 + num_buffers * 4 wraps to 2 and the bounds ...

In the Linux kernel, the following vulnerability has been resolved: drm: Fix drm_crtc_commit leak if signaled when PAGE_FLIP_EVENT is used Commit 1c6ceeee6ebb ("drm/atomic: Fix memleak on ERESTARTSYS during non-blocking commits") fixed a very simil...

In the Linux kernel, the following vulnerability has been resolved: drm/gud: NUL-terminate TV mode names read from the device gud_connector_add_tv_mode() reads a buffer of fixed-size mode names from the USB device and passes pointers into it to drm...
