CVE-2026-64521: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: pinctrl: meson: amlogic-a4: fix deadlock issue Accessing the pinconf-pins sysfs node may deadlock. pinconf_pins_show() holds pctldev->mutex, and the platform driver calls pinctrl_find_gpio_range_from_pin(), which tries to acquire the same mutex again, leading to a deadlock. Use pinctrl_find_gpio_range_from_pin_nolock() to fix this issue.
