Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: iio: adc: ti-adc161s626: use DMA-safe memory for spiread Add a DMA-safe buffer and use it for spiread instead of stack memory. All SPI buffers must be DMA-safe. Since we only need up to 3 bytes, we simply use a u8 instead of be16...

SUSE CVE-2026-53344

In the Linux kernel, the following vulnerability has been resolved: pinctrl: mcp23s08: Initialize mcp-dev and mcp-addr before regmap init Regmap initialization triggers regcachemaplepopulate which attempts SPI read to populate cache. SPI read requires mcp-dev and mcp-addr to be set, without them,...

CVE-2026-53344 pinctrl: mcp23s08: Initialize mcp->dev and mcp->addr before regmap init

CVE-2026-53344

CVE-2026-53344 affects the Linux kernel in the pinctrl: mcp23s08 driver. The issue occurs during regmap initialization when SPI reads run before critical mcp->dev and mcp->addr are set, causing a NULL pointer dereference during probe. The fix moves the initialization of mcp->dev and mcp-...

CVE-2026-31768

The CVE-2026-31768 issue affects the Linux kernel driver iio: adc: ti-adc161s626, where SPI read operations used non-DMA-safe stack memory. The mitigation is to allocate a DMA-safe buffer and perform spi_read() into that buffer, replacing stack-based buffers. Since the read would require only up ...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the iio adc i-adc161s626 driver's use of stack memory for spiread, which could lead to unsafe DMA...
