The Linux kernel's peak_usb module has a vulnerability that requires validation of uCAN receive record lengths. The pcan_usb_fd_decode_buf function walks uCAN records packed in one USB receive buffer and requires each record to contain the fixed header for its type, and verifies CAN payload bytes before copying them into the skb. This vulnerability affects Linux kernel users and administrators who need to [truncated]
The Linux kernel's drm/vc4 component has a vulnerability where it incorrectly supplies the overflow slot size in BPOS, leading to potential memory corruption. This could result in GPU hangs, userspace heap corruption, and full system crashes. The bug has been resolved by correcting the overflow slot size. Users of the Linux kernel, particularly those using the drm/vc4 component, should be aware of this vu [truncated]
The Linux kernel vulnerability, CVE-2026-74453, relates to the drm/vc4 component. A binner BO is a 16MB buffer divided into 512KB slots for jobs, which are recycled without clearing. Each slot contains a Tile State Data Array (TSDA) and a tile allocation pool. The TSDA is used by the hardware and must be cleared to prevent GPU hangs from stale tile states. Zeroing the TSDA when configuring a job's binning [truncated]
The CVE-2026-74452 vulnerability is related to the Linux kernel's drm/panthor component. A potential heap buffer overflow and out-of-bounds memory zeroing issue exist due to improper validation of firmware section data sizes. This could be triggered by crafted firmware with oversized data sections. The vulnerability may impact Linux kernel users, and it is essential to verify system configurations and app [truncated]
The Linux kernel has a use-after-free vulnerability in the drm/amd/pm component. The amdgpu_dpm_get_pp_table() function returns a pointer to a driver-owned power table after dropping adev->pm.mutex. A concurrent pp_table write can replace and free the allocation during the copy, causing a use-after-free. This vulnerability affects Linux kernel developers and users, amd gpu users, and others who rely on th [truncated]
A use-after-free vulnerability was discovered in the Linux kernel's drm/amdkfd component. The vulnerability occurs when MES is enabled and amdgpu_amdkfd_alloc_kernel_mem() fails during the first queue creation for a process. This leads to a QID bit leak in pqm_create_queue(), potentially exhausting all available queue slots over time. The affected product is the Linux kernel, specifically the drm/amdkfd c [truncated]
The Linux kernel has a vulnerability in the drm/amdkfd component that could lead to a GPU fault. The issue arises from a uint32_t overflow in EOP ring buffer size alignment, which can cause the CP EOP writes to land past the buffer.

This vulnerability impacts Linux kernel developers, administrators, and users of systems with the affected kernel version, pote [truncated]
A synchronization issue exists in the Linux kernel's USB type-C UCSI port unregistration, leading to use-after-free conditions. The vulnerability has been resolved by ensuring strict ordering and proper serialization during teardown. This involves moving ucsi_unregister_partner() to the beginning of the teardown sequence and protecting it under the connector mutex lock. Additionally, all pending partner t [truncated]
The Linux kernel has a vulnerability in the drm/xe component. The vulnerability arises from the drm/xe: Wait on external BO kernel fences in exec IOCTL. Before arming a user job, xe_exec_ioctl() only added the VM's dma-resv KERNEL slot as a dependency. This could lead to a user job being scheduled while a kernel operation on an external BO mapped by the VM was still in flight, potentially reading or writi [truncated]
The Linux kernel vulnerability, CVE-2026-74439, involves a flaw in the iommu/vt-d module where the Present bit is not cleared before tearing down scalable-mode context entries. This can lead to unpredictable behavior or spurious faults. The issue arises from the device_pasid_table_teardown() function, which zeroes the 128-bit scalable-mode context entry with context_clear_entry() while the Present bit is [truncated]
