CVE-2024-26817-amdkfd

-- CVE-2024-26817 I found a security vulnerability in AMD KFD in the following file drivers/gpu/drm/amd/amdkfd/kfdchardev.c, the ioctl identifier is AMDKFDIOCGETPROCESSAPERTURESNEW. In the function kfdioctlgetprocessaperturesnew, the user-provided data of args-numofnodes will be multiplied and...

CVE-2026-90035

A flaw was found in the drm/amd/display component of the Linux kernel. A local attacker, by connecting a specially crafted USB4/DPIA tunneling device, could trigger a division-by-zero error within the getestimatedbw function. This occurs when the device reports an estimated-bandwidth change befor...

CVE-2026-89812

A flaw was found in the Linux kernel's AMD GPU Graphics Processing Unit driver. When the Multimedia Engine Scheduler MES ring stops responding and a system reset is triggered, the MES ring fences are not properly completed. This can lead to the system becoming unresponsive after resuming from the...

CVE-2026-93179

A flaw was found in the drm/amd/powerplay component of the Linux kernel. This vulnerability occurs when the VBIOS Video Basic Input/Output System provides a malformed VoltageObjectInfo table, which can lead to an infinite loop or an out-of-bounds OOB read in the system's memory. This could...

CVE-2026-93177

A flaw was found in the Linux kernel's AMD GPU powerplay module. This vulnerability arises from missing bounds checks when processing voltage indices from VBIOS-parsed tables. An attacker could potentially exploit this by providing specially crafted VBIOS data, leading to an out-of-bounds read...

CVE-2026-93176

A flaw was found in the Linux kernel's AMD display drm/amd/display driver. Specifically, the amdgpudmplanedrmplanereset function attempts to free memory before successfully allocating a new state. Should the new memory allocation fail, a dangling pointer to the previously freed memory remains. Th...

CVE-2026-93175

A flaw was found in the Linux kernel's display driver for AMD graphics, specifically within the drm/amd/display component. This vulnerability occurs in the amdgpudmcrtcresetstate function when it attempts to reset the display state. If a memory allocation fails during this process, the system can...

CVE-2026-93068

A flaw was found in the Linux kernel's AMD display DM I2C adapter. A race condition exists where the DM I2C adapters remain visible to userspace while the DM teardown is in progress. A local attacker could exploit this by initiating a concurrent i2c-dev transfer, causing a NULL pointer dereferenc...

CVE-2026-92505

A flaw was found in the Linux kernel's iommu/amd component, specifically within the devidwrite debugfs function. When the foreachpcisegment loop fails to find a matching segment, a pointer can reference an invalid memory location. Accessing this invalid memory can lead to undefined behavior,...

CVE-2026-92492

A flaw was found in the Linux kernel's cpufreq/amd-pstate component. A local attacker could potentially trigger a NULL pointer dereference by performing a racing CPU hotplug or driver teardown operation. This occurs because certain functions, amdpstatepowersupplynotifier and amdpstateprofileset, ...

CVE-2026-98472

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine AMD SEV Secure Encrypted Virtualization implementation. This flaw allows a local user with permissions to manage virtual machines to cause a denial of service DoS through memory exhaustion. When an SEV guest is destroyed afte...

CVE-2026-98471

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for AMD SEV Secure Encrypted Virtualization. During intra-host migration of an encrypted virtual machine, the source virtual machine's CPU caches are not properly flushed before the system reclaims its memory. A loc...
