CVE-2026-46081

A flaw was found in the Linux kernel's asynchronous compression acomp subsystem. When an asynchronous hardware implementation, such as the QAT driver, completes a request that uses the DMA virtual address interface, an incorrect pointer is stored. This leads to memory corruption within the...

CVE-2026-46091

A flaw was found in the igorplugusb component of the Linux kernel. The USB request structure, when handled by Direct Memory Access DMA on certain host controllers, did not properly follow DMA coherency rules. This oversight could lead to data integrity issues or unexpected system behavior, as the...

UBUNTU-CVE-2026-46007

As the buffer may be used for DMA, that is problematic. Use the high-level DMA...

UBUNTU-CVE-2026-46077

In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-tdes - fix DMA sync direction Before DMA output is consumed by the CPU, -dmaaddrout must be synced with dmasyncsingleforcpu instead of dmasyncsinglefordevice. Using the wrong direction can return stale cache data on...

In the Linux kernel, the following vulnerability has been resolved: RDMA/iwcm: Fix workqueue list corruption by removing worklist The commit e1168f0 "RDMA/iwcm: Simplify cmeventhandler" changed the work submission logic to unconditionally call queuework with the expectation that queuework would...

UBUNTU-CVE-2026-45894

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear Present bit before tearing down PASID entry The Intel VT-d Scalable Mode PASID table entry consists of 512 bits 64 bytes. When tearing down an entry, the current implementation zeros the entire 64-byte structure...

EUVD-2026-32474

In the Linux kernel, the following vulnerability has been resolved: media: rc: igorplugusb: heed coherency rules In a control request, the USB request structure can be subject to DMA on some HCs. Hence it must obey the rules for DMA coherency. Allocate it separately...

CVE-2026-46091

CVE-2026-46091 : Linux kernel vulnerability in the igorplugusb driver where a USB control request may be subject to DMA, violating DMA coherency rules. The resolution requires allocating the affected structure separately to enforce coherency. Public records identify the issue across multiple dist...

EUVD-2026-32459

In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-tdes - fix DMA sync direction Before DMA output is consumed by the CPU, -dmaaddrout must be synced with dmasyncsingleforcpu instead of dmasyncsinglefordevice. Using the wrong direction can return stale cache data on...

CVE-2026-46077

CVE-2026-46077 involves a Linux kernel crypto module (atmel-tdes) where DMA sync direction was incorrect. The issue occurs when DMA output was consumed by the CPU and the address_out was not synced with the CPU correctly, risking stale data on non‑coherent platforms. The published fixes switch to...

CVE-2026-46043

The CVE-2026-46043 detail shows a Linux kernel RDMA/rxe issue in rxe_rcv() where payload_size() could underflow due to attacker-controlled BTH pad and RXE_ICRC_SIZE not being accounted for in the initial length check. The fix requires validating paylen against the full minimum length: header_size...

CVE-2026-46043

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Validate pad and ICRC before payloadsize in rxercv rxercv currently checks only that the incoming packet is at least headersizepkt bytes long before payloadsize is used. However, payloadsize subtracts both the...
