CVE-2026-64521
Overview
CVE-2026-64521 is a known-severity vulnerability. It was published on July 25, 2026.
Technical Description
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.
