CVE-2026-68417 RDMA/siw: publish QP after initialization

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siwcreateqp currently calls siwqpadd before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being...

CVE-2026-68330

CVE-2026-68330 affects the Linux kernel component for net: airoha mailbox buffers. The issue arises because airoha_npu_send_msg() always maps with DMA_TO_DEVICE, while some callers rely on the NPU to write responses back into the same buffer. On non-cache-coherent systems (e.g., EN7581 Cortex-A53...

In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: make releasescratchbuffers idempotent brcmfpciereleasescratchbuffers frees the shared.scratch and shared.ringupd DMA buffers with dmafreecoherent but does not clear the pointers afterwards, unlike the sibling...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: dmaengine: fsl-edma: Do not explicitly disable clocks in .remove The clocks in fsledmaengine::muxclk are allocated and enabled using devmclkgetenabled, which automatically cleans up these resources. However, these clocks are...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: usb: ChipIdea UDC: Fix for DMA and SG cleanup in epnuke The ChipIdea UDC driver may encounter errors where “not-page-aligned sg buffers” occur when a USB device is reconnected after being disconnected during an active transfer...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: The issue involves fixing a situation where the NULL pointer of the DMA device was dereferenced, without ensuring that cdnsctrl-dmac was properly initialized first. The pointer dmadev was being dereferenced...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Net: Ethernet: ecbhf: Fixed the dmafreecoherent function’s DMA handle. The error-prone use of dmafreecoherent takes priv-rxbuf.alloclen as the DMA handle. This could result in improper unmapping of the buffer. The DMA handle has...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: fbdev: vt8500lcdfb: fixed the issue where dmafreecoherent was not called when memory was freed. The fbi-fb.screenbuffer is allocated using dmaalloccoherent, but it is not freed if an error path occurs...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: xdp: generate a warning when the calculated tailroom is negative Many Ethernet drivers report that the xdp Rx queue frag size is the same as the DMA write size. However, the only user of this field, namely bpfxdpfragsincreasetail...

In the Linux kernel, the following vulnerability has been resolved: media: cx88: Add the missing unmap in sndcx88hwparams In the error path, add cx88alsadmaunmap to release the resource acquired by cx88alsa DMAmap...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dmaengine: stm32: dmamux: fix device leak on route allocation Make sure to release the reference taken when looking up the DMA mux platform device during route allocation...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: ath10k – Fix for the dmafreecoherent pointer dmaalloccoherent allocates a DMA-mapped buffer and stores the addresses in XXXunaligned fields. These addresses should be reused when freeing the buffer, rather than using the...

CVE-2026-45204 GPU DDK - Out of bounds memory access and kernel NULL pointer dereference in DmaTransfer when pui64Address is a pointer to device memory

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger OOB access and kernel null pointer dereference in an error path. Null pointer dereference occurs in an error path of a function running in kernel thread of execution leading to kernel exceptions,...

CVE-2026-64582

A flaw was found in the Linux kernel's RDMA/rxe component. A race condition in the rxemmap function, which manages memory for Remote Direct Memory Access RDMA operations, can lead to a use-after-free vulnerability. A local attacker could exploit this timing issue to cause a system crash, resultin...

CVE-2026-64590 dma-buf/udmabuf: skip redundant cpu sync to fix cacheline EEXIST warning

In the Linux kernel, the following vulnerability has been resolved: dma-buf/udmabuf: skip redundant cpu sync to fix cacheline EEXIST warning When CONFIGDMAAPIDEBUGSG is enabled, importing a udmabuf into a DRM driver e.g. amdgpu for video playback in GNOME Videos / Showtime triggers a spurious...

Linux Distros Unpatched Vulnerability : CVE-2026-64590

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - dma-buf/udmabuf: skip redundant cpu sync to fix cacheline EEXIST warning When CONFIGDMAAPIDEBUGSG is enabled, importing a udmabuf into a DRM driver e.g. amdgpu...

netty-codec-redis: Netty's Lack of Lifecycle Cleanup Leads to Pooled ByteBuf Leak in RedisArrayAggregator

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by repeatedly closing Redis pipeline connections before a Redis array aggregate completes. This leads to a permanent leak of direct-memory buffers, which prevents memory chunks from being returned to the share...
