Panthor driver Heap Buffer Overflow DoS

The vulnerability of the panthorfwunplug function in the drivers/gpu/drm/panthor/panthorfw.c file of the Panthor driver which provides DRM support for ARM Mali CSF-based graphics processors in the Linux operating system is related to pointer manipulation. Exploiting this vulnerability could allow...

PT-2026-94976

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference occurs in the panthor driver during the split of GPU mapping caused by a partial unmap of an evicted Buffer Object BO. The issue arises because the logic...

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...

Panthor driver Kernel Buffer Overflow

The vulnerability of the panthorkernelbodestroy function in the drivers/gpu/drm/panthor/panthorgem.c file of the Panthor driver which provides DRM support for ARM Mali CSF-based graphics processors in the Linux operating system is related to the reutilization of previously freed memory. Exploitin...

SUSE CVE-2026-74451

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: validate firmware interface structure sizes ifacefwtocpuaddr only checks that the firmware-provided MCU virtual address points inside the shared section. The returned pointer is later used as a full firmware interfac...

SUSE CVE-2026-74452

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: reject firmware sections with oversized data In panthorfwloadsectionentry, the data size to copy is calculated without validating it against the allocated sectionsize: section-data.size = hdr.data.end - hdr.data.star...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the drm/panthor component where the iface fw to cpu addr function only verifies that the MCU virtual address provided by the firmware points within the shared section...

SUSE-SU-2026:21845-1 Security update for the Linux Kernel

The SUSE Linux Enterprise 16.0 kernel was updated to fix various security issues The following security issues were fixed: - CVE-2023-2058: x86/CPU: Fix FPDSS on Zen1 bsc1243603. - CVE-2024-14027: xattr: switch to CLASSfd bsc1259420. - CVE-2025-40181: x86/kvm: Force legacy PCI hole to UC when...

Linux Kernel Security Vulnerabilities

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the panthorfwunplug function in the drm/panthor driver. This function calls the MCU to pause and...

CVE-2025-71302

A flaw was found in the Linux kernel, specifically within the drm/panthor graphics driver. This vulnerability involves a race condition, a situation where multiple operations occur at the same time in an unpredictable order. Specifically, the drmschedfencegettimelinename function can race with...
