Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1 Description An issue exists in the atmel-tdes crypto component where the DMA output dma addr out is synced using dma sync single for...

PT-2026-43874

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified openSUSE Tumbleweed versions prior to kernel-devel-7.0.11-1.1 Description In the hwmon powerz component, a DMA buffer may share a cacheline with a mutex depending on the architecture. This cacheline...

Securing High-Performance Data Transfers: Implementing AES Encryption in RDMA Systems

Remote Direct Memory Access RDMA is a key enabler of high-performance systems, offering low latency, high throughput, and reduced CPU overhead by allowing direct memory-to-memory transfers between machines. However, its design bypasses traditional CPU-mediated security mechanisms, introducing...

kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...

Astra Linux - уязвимость в linux-5.10, linux

In the Linux kernel, the following vulnerability has been resolved: tty: serial: fsllpuart: disable dma rx/tx use flags in lpuartdmashutdown lpuartdmashutdown tears down the lpuart DMA, but lpuartflushbuffer can still occur, which attempts to access DMA APIs if the lpuartdmatxuse flag is true...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: nvmet: moving async event work off nvmet-wq For the target function nvmetctrlfree, the variable ctrl-asynceventwork is flushed. If nvmetctrlfree runs on nvmet-wq, the flush re-enters the workqueue completion for the same worker. ...

Astra Linux - уязвимость в linux-5.15, linux-6.1

In the Linux kernel, the following vulnerability has been resolved: SPI: sun6i – Fixed a race condition between DMA RX transfer completion and RX FIFO drain. Previously, the transfer-completion interrupt would immediately drain the data from the RX FIFO into the RX buffer. This behavior was corre...

Astra Linux - уязвимость в linux

In the Linux kernel, the following vulnerability has been resolved: Net: lantiq – fixed memory corruption in the RX ring. In a situation where memory allocation or DMA mapping fails, an invalid address may be programmed into the descriptor. This can lead to memory corruption. If memory allocation...

Astra Linux - уязвимость в linux-5.10, linux-6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: safexcel – Add error handling for dmamapsg calls The macro dmamapsg function may return 0 in the event of an error. This patch enables checks in case of a macro failure and ensures that previously mapped buffers are...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: dma-debug: prevents an error message from causing runtime problems. For some drivers that use the DMA API, this error message can occur several million times per second. This can lead to excessive use of the kernel’s printk buffe...

Astra Linux - уязвимость в linux-5.10, linux

In the Linux kernel, the following vulnerability has been resolved: spi: bcm2835: bcm2835spihandleerr: Fixed the issue of NULL pointer dereferencing during non-DMA transfers. In cases where an IRQ-based transfer times out, the bcm2835spihandleerr function is called. Since commit 1513ceee70f2 “spi...

Astra Linux - уязвимость в linux-5.10

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 bpfxdpfragsincreasetai...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: spi: spi-fsl-dspi: A resource leak was fixed in the error handling path. The call dspirequestdma should be undone by a call to dspireleasedma in the error handling path of the probe function, as already done in the remove functio...

Astra Linux - уязвимость в linux-6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fixed the incorrect order of resource deallocation. When attempting to destroy a QP or CQ, we first reduce the reference count and potentially free the memory regions allocated for the object. Then, we request the devic...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: net: spacemit: Fix error handling in emactxmemmap The DMA mappings were exposed due to mapping errors. These mappings can now be freed using the existing emacfreetxbuf function...

Astra Linux - уязвимость в qemu

A heap buffer overflow was discovered in the floppy disk emulator of QEMU up to version 6.0.0 inclusive. This issue could occur in the fdctrltransferhandler function in the hw/block/fdc.c file, during the processing of DMA read data transfers from the floppy drive to the guest system. A privilege...
