CVE-2026-74446 drm/amdkfd: hold event_mutex while checkpointing CRIU events

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: hold eventmutex while checkpointing CRIU events kfdcriucheckpointevents counts the entries in p-eventidr via kfdgetnumevents, allocates an array sized to that count, and then walks the same IDR to fill it. Neither the...

CVE-2026-74445

The CVE (CVE-2026-74445) affects the Linux kernel drm/vmwgfx path. The vulnerability arises when vmw_cmd_dx_bind_query() dereferences sw_context->dx_ctx_node->ctx if a DX_BIND_QUERY is submitted with dx_context_handle set to SVGA3D_INVALID_ID, allowing a NULL pointer dereference and kernel ...

CVE-2026-74446

The CVE-2026-74446 issue affects the Linux kernel DRM/AMDKFD path and is triggered in kfd_criu_checkpoint_events() when checkpointing CRIU events. The root cause is that kfd_criu_checkpoint_events() counts entries in p->event_idr without holding p->event_mutex, and later iterates the same I...

CVE-2026-74444

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: validate DRAWPRIMITIVES header size before division vmwcmddraw computes maxnum = header-size - sizeofcmd-body / sizeofdecl; where header-size is u32 and is taken straight from the user-supplied command stream. When...

CVE-2026-74444

The vulnerability CVE-2026-74444 affects the Linux kernel DRM vmwgfx driver. In vmw_cmd_draw, the header size from user input can cause an unsigned subtraction (header->size - sizeof(cmd->body)) to wrap to ~4 GiB when header->size is undersized, leading to a large maxnum and an out-of-bo...

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: avoid destroyworkqueueNULL on vkms init failure Two paths through vmwvkmsinit can leave vmw-crcworkq NULL while still leaving the rest of the driver in a state that calls vmwvkmscleanup at module unload: 1...

CVE-2026-74443

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: bound DMA command body size against suffix pointer vmwcmddma locates the DMA suffix at unsigned long &cmd-body + header-size - sizeofsuffix without checking that header-size is large enough to contain both cmd-body an...

CVE-2026-74443

CVE-2026-74443 affects the Linux kernel DRM/vmwgfx path. The issue in vmw_cmd_dma() computes the DMA suffix location without ensuring header->size can contain both body and suffix, allowing an undersized header to underflow the suffix pointer and later overwrite verified fields of a relocated ...

CVE-2026-74442

CVE-2026-74442 affects the Linux kernel drm/vmwgfx/vkms code. Two code paths in vmw_vkms_init() can leave vmw->crc_workq NULL while the driver is not fully unload-safe, causing a panic when vmw_vkms_cleanup() runs destroy_workqueue(NULL). Fixes: (1) remove the early return so the workqueue is ...
