CVE-2024-41089: drm/nouveau/dispnv04: fix null pointer dereference in nv17_tv_get_hd_modes
First published: Mon Jul 29 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/dispnv04: fix null pointer dereference in nv17_tv_get_hd_modes In nv17_tv_get_hd_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate(). The same applies to drm_cvt_mode(). Add a check to avoid null pointer dereference.
