CVE-2026-46269

In the Linux kernel, the following vulnerability has been resolved: pinctrl: canaan: k230: Fix NULL pointer dereference when parsing devicetree When probing the k230 pinctrl driver, the kernel triggers a NULL pointer dereference. The crash trace showed: 0.732084 Unable to handle kernel NULL point...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the k230 pinctrl driver’s parsing of the device tree. This parsing process involves accessing...

The vulnerability of the pinmux_func_name_to_selector() function in the drivers/pinctrl/pinmux.c file of the GPIO controller driver for Linux kernel, which allows an attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the pinmuxfuncnametoselector function in the drivers/pinctrl/pinmux.c file, a driver for LINUX operating system GPIO controllers, is related to the lack of checking the return value. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

CVE-2025-38266

CVE-2025-38266 affects the Linux kernel pinctrl/mediatek EINT path. The root cause was an invalid dereference: a function (mtk_eint_do_init) could be called with a version of struct mtk_pinctrl that lacks the required soc field when using v1 drivers, leading to a potential crash on certain boards...

CVE-2022-49608 pinctrl: ralink: Check for null return of devm_kcalloc

In the Linux kernel, the following vulnerability has been resolved: pinctrl: ralink: Check for null return of devmkcalloc Because of the possible failure of the allocation, data-domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better t...

CVE-2022-49449

The CVE-2022-49449 issue affects Linux kernel pinctrl: renesas: rzn1. The root cause is a possible null-ptr-deref when using 'res' if platform_get_resource() returns NULL. The patch defers dereferencing 'res' by performing devm_ioremap_resource() first (which validates the resource) and then uses...

CVE-2024-57889

CVE-2024-57889 is resolved in the Linux kernel via a patch to the pinctrl-mcp23s08 driver. The issue occurred when using MCP23xxx IO expanders to receive IRQs, where regmap locking (mutex) around regmap_update_bits_base was invoked from a context that held a spinlock in __setup_irq(), leading to ...
