CVE-2026-64521

A flaw was found in the Linux kernel's pinctrl subsystem for Amlogic A4 devices. A local attacker could trigger a deadlock by accessing the pinconf-pins sysfs node. This occurs because the pinconfpinsshow function attempts to acquire a mutex that is already held, leading to a system freeze or...

CVE-2026-64521

CVE-2026-64521 affects the Linux kernel pinctrl subsystem (meson: amlogic-a4). The deadlock arises when pinconf_pins_show() holds pctldev->mutex while pinctrl_find_gpio_range_from_pin() tries to re-acquire the same mutex; the fix is to use pinctrl_find_gpio_range_from_pin_nolock() to avoid the...

CVE-2026-53344

A flaw was found in the Linux kernel's pinctrl: mcp23s08 driver. During the initialization of the regmap register map for the mcp23s08 component, an attempt to perform an SPI Serial Peripheral Interface read occurs before critical device parameters mcp-dev and mcp-addr are properly set. This...

CVE-2026-53340

A flaw was found in the Linux kernel's i2c: imx driver. During runtime power management, an inconsistency between the clock and pinctrl states can occur. If the pinctrl state fails to switch to sleep mode after the clock is disabled, the clock remains off. This can lead to a system crash when the...
