CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's pin control subsystem, specifically within the Amlogic A4 platform driver, where accessing the pinconf-pins sysfs node can lead to a deadlock due to improper mutex handling. This can disrupt system operations and potentially lead to denial of service. Linux system administrators and developers working with Amlogic A4 hardware should prioritize applying the fix to prevent potential system hang scenarios.
Original NVD 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.
