CVE-2026-23308

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.12.59+

Description The Linux kernel contains an issue within the pinctrl subsystem, specifically related to the equilibrium driver. The callback functions eqbr irq mask() and eqbr irq ack() are unnecessarily called within the eqbr irq mask ack() function. This results in the gpiochip disable irq() function being invoked, generating warning traces in the system log during GPIO initialization. This occurs because the interrupt is not disabled in the drivers/pinctrl/starfive/pinctrl-starfive-jh7100.c driver.

Recommendations Update to Linux kernel version 6.12.59+ or later. Do not call the eqbr irq mask() and eqbr irq ack() functions. Implement the necessary functionality directly without disabling interrupts.
