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...

CVE-2026-45856

In the Linux kernel, the following vulnerability has been resolved: RDMA/uverbs: Validate wqesize before using it in ibuverbspostsend ibuverbspostsend uses cmd.wqesize from userspace without any validation before passing it to kmalloc and using the allocated buffer as struct ibuverbssendwr. If a...

UBUNTU-CVE-2026-45852

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix double free in rxesrqfrominit In rxesrqfrominit, the queue pointer 'q' is assigned to 'srq-rq.queue' before copying the SRQ number to user space. If copytouser fails, the function calls rxequeuecleanup to free the...

libsolv: Heap buffer overflow in libsolv repopagestore via unchecked decompression of malicious .solv page data

A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within .solv files due to insufficient input validation. An attacker can provide a specially crafted .solv file, which, when processed by a vulnerable application, can lea...

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-2026-32474

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-2026-46084

In the Linux kernel, the following vulnerability has been resolved: RDMA/manaib: Disable RX steering on RSS QP destroy When an RSS QP is destroyed e.g. DPDK exit, manaibdestroyqprss destroys the RX WQ objects but does not disable vPort RX steering in firmware. This leaves stale steering...

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-2026-46077 crypto: atmel-tdes - fix DMA sync direction

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-2026-46067 mm/damon/core: validate damos_quota_goal->nid for node_memcg_{used,free}_bp

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: validate damosquotagoal-nid for nodememcgused,freebp Users can set damosquotagoal-nid with arbitrary value for nodememcgused,freebp. But DAMON core is using those for NODE-DATA without a validation of the value. Th...

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...

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...
