CVE-2024-27041
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix NULL checks for adev->dm.dc in amdgpu_dm_fini() Since 'adev->dm.dc' in amdgpu_dm_fini() might turn out to be NULL before the call to dc_enable_dmub_notifications(), check beforehand to ensure there will not be a possible NULL-ptr-deref there. Also, since commit 1e88eb1b2c25 ("drm/amd/display: Drop CONFIG_DRM_AMD_DC_HDCP") there are two separate checks for NULL in 'adev->dm.dc' before dc_deinit_callbacks() and dc_dmub_srv_destroy(). Clean up by combining them all under one 'if'. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: corrige comprobaciones NULL para adev->dm.dc en amdgpu_dm_fini() Dado que 'adev->dm.dc' en amdgpu_dm_fini() podría resultar ser NULL antes de llamar a dc_enable_dmub_notifications(), verifique de antemano para asegurarse de que no habrá un posible NULL-ptr-deref allí. Además, desde la confirmación 1e88eb1b2c25 (\"drm/amd/display: Drop CONFIG_DRM_AMD_DC_HDCP\") hay dos comprobaciones separadas para NULL en 'adev->dm.dc' antes de dc_deinit_callbacks() y dc_dmub_srv_destroy(). Limpia combinándolos todos bajo un solo \"si\". Encontrado por el Centro de verificación de Linux (linuxtesting.org) con la herramienta de análisis estático SVACE."
