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...
