CVE-2024-53084 drm/imagination: Break an object reference loop

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Break an object reference loop When remaining resources are being cleaned up on driver close, outstanding VM mappings may result in resources being leaked, due to an object reference loop, as shown below, with ea...

CVE-2024-53084

CVE-2024-53084 affects the Linux kernel’s DRM/Imagination driver path for PVR, where a resource cleanup reference loop between PVR VM Context and VM Mappings could leak VM resources. The official fix breaks the loop by freeing outstanding VM mappings before destroying the PVR Context associated w...

CVE-2024-53080 drm/panthor: Lock XArray when getting entries for the VM

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Lock XArray when getting entries for the VM Similar to commit cac075706f29 "drm/panthor: Fix race when converting group handle to group object" we need to use the XArray's internal locking when retrieving a vm pointe...

CVE-2024-53080

The CVE concerns the Linux kernel’s panthor driver. A vulnerability in panthor_vm_pool_get_vm() (drivers/gpu/drm/panthor/panthor_mmu.c) arises from incorrect locking while retrieving a VM pointer from the panthor pool. The underlying issue is improper use of XArray locking, which could allow a lo...

CVE-2024-53078

In CVE-2024-53078, Linux kernel vulnerability exists in drm/tegra: probe() where the code checked for NULL after calling iommu_paging_domain_alloc(). The function does not return NULL pointers; it returns error pointers. The fix updates the check to treat error pointers correctly, aligning the pr...

CVE-2024-53071 drm/panthor: Be stricter about IO mapping flags

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Be stricter about IO mapping flags The current panthordevicemmapio implementation has two issues: 1. For mapping DRMPANTHORUSERFLUSHIDMMIOOFFSET, panthordevicemmapio bails if VMWRITE is set, but does not clear...

CVE-2024-53071

CVE-2024-53071 affects the Linux kernel's drm/panthor driver. The panthor_device_mmap_io() path mishandles two IO-mapped regions: (1) it bails when VM_WRITE is set for DRM_PANTHOR_USER_FLUSH_ID_MMIO_OFFSET but does not clear VM_MAYWRITE, potentially allowing userspace to writable mappings later v...

CVE-2024-53060 drm/amdgpu: prevent NULL pointer dereference if ATIF is not supported

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: prevent NULL pointer dereference if ATIF is not supported acpievaluateobject may return AENOTFOUND failure, which would result in dereferencing buffer.pointer obj while being NULL. Although this case may be unrealisti...

CVE-2024-53060

CVE-2024-53060 (Linux kernel) affects drm/amdgpu: fixes a NULL pointer dereference when ATIF is not supported. The kernel may dereference buffer.pointer (obj) if acpi_evaluate_object() returns AE_NOT_FOUND, so the fix adds a bailout when AE_NOT_FOUND occurs to prevent NULL dereference. The Note i...
