CVE-2026-46007

A flaw was found in the Linux kernel's hwmon powerz component. This vulnerability is caused by cacheline sharing between the transfer buffer and a mutex during Direct Memory Access DMA operations. This architectural issue can lead to unexpected behavior or data corruption, impacting system...

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-2026-45894

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...

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...
