CVE-2022-50842 drm/virtio: Check whether transferred 2D BO is shmem

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: Check whether transferred 2D BO is shmem Transferred 2D BO always must be a shmem BO. Add check for that to prevent NULL dereference if userspace passes a VRAM BO...

CVE-2022-50842

CVE-2022-50842 affects the Linux kernel DRM virtio path. The issue arises when transferring 2D buffer objects (BOs); a non-shmem BO (e.g., VRAM) could bypass a necessary check, potentially leading to a NULL dereference. The publicly documented fix is to validate that a transferred 2D BO is always...

CVE-2023-54196

Linux kernel ntfs3: CVE-2023-54196 fix addresses NULL pointer dereference in ni_write_inode. Root cause: during inode creation, ntfs_new_inode may allocate mi->mrec; if allocation fails, mrec is NULL, and later code path ntfs_evict_inode calls is_rec_inuse(ni->mi.mrec) leading to oops. The ...
