CVE-2026-93180

CVE-2026-93180 affects the Linux kernel's drm/panthor GPU driver. A NULL pointer dereference occurs when a GPU memory mapping is split during a partial unmap of an evicted Buffer Object (BO) . The root cause is that the logic handling partial unmap of huge pages was not fully skipped for the VMA ...

CVE-2026-90409 drm/panthor: Add vm_bind region with kbo range overlap check

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Add vmbind region with kbo range overlap check When a VM is created, caller has to specify the range of the address space carve-out set aside for mapping kernel BO's. That means vmbind mappings of UM-exposed BO's...

CVE-2026-90409

CVE-2026-90409 affects the Linux kernel drm/panthor driver. The root cause is a missing overlap check: when a VM is created, the caller specifies an address-space carve-out for mapping kernel buffer objects (BOs), yet vm_bind mappings of user-mode-exposed BOs were not verified to stay outside tha...

CVE-2026-89826 drm/panthor: harden firmware build-info bounds checks

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: harden firmware build-info bounds checks panthorfwreadbuildinfo checks whether the metadata range fits in the firmware image with hdr.metastart + hdr.metasize. Both fields are u32, so the addition can wrap and let an...

CVE-2026-89826

This vulnerability affects the Linux kernel 's drm/panthor GPU driver, specifically the panthor_fw_read_build_info() function. Two related flaws allow an out-of-bounds memory read: (1) the metadata range validation uses addition of two u32 fields (hdr.meta_start + hdr.meta_size), which can wrap a...

CVE-2026-80577

A flaw was found in the Linux kernel's drm/panthor driver. When the panthorfwloadsectionentry function processes zero-sized firmware sections, it can leave a memory pointer uninitialized. Subsequent operations that attempt to access this uninitialized memory can lead to a null pointer dereference...
