CVE-2026-74285

A flaw was found in the Linux kernel's network subsystem. An issue in the netifrxqcleanupunlease function, responsible for tearing down network queue memory providers, allows a device to perform Direct Memory Access DMA to an incorrect memory address. This occurs because the DMA mappings are...

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 relates to the Linux kernel net/airoha NPU mailbox handling. The issue arises because airoha_npu_send_msg() always maps the mailbox buffer with DMA_TO_DEVICE, while some callers expect the NPU to write the response back into the same buffer. On non‑cache‑coherent architectures (e.g...

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 6.1

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 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 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...

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 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 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...
