CVE-2026-68261

A flaw was found in the Linux kernel's drm/imagination component. A local user could exploit this vulnerability by passing an invalid virtual machine VM context handle to the DRMIOCTLPVRCREATECONTEXT ioctl. This improper error checking can lead to a kernel crash, resulting in a Denial of Service...

DEBIAN-CVE-2026-68261

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: fix error checking of pvrvmcontextlookup Since pvrvmcontextlookup returns either NULL or a pointer, then stop using ISERR for checking the return value. Using ISERR leads to the kernel oops reported below. It can...

CVE-2026-68239

CVE-2026-68239 affects the Linux kernel DRM TTM code, specifically the ttm_pool_backup path. The issue arises because ttm_pool_backup could encounter NULL or backup handle entries (ttm_backup_page_ptr_is_handle()) which were not safely guarded for set_pages_array_wb() and could be freed erroneous...
