Overview

CVE-2024-56671 is a medium-severity vulnerability affecting linux linux_kernel. It was published on December 27, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

gpio: graniterapids: Fix vGPIO driver crash

Move setting irq_chip.name from probe() function to the initialization

of "irq_chip" struct in order to fix vGPIO driver crash during bootup.

Crash was caused by unauthorized modification of irq_chip.name field

where irq_chip struct was initialized as const.

This behavior is a consequence of suboptimal implementation of

gpio_irq_chip_set_chip(), which should be changed to avoid

casting away const qualifier.

Crash log:

BUG: unable to handle page fault for address: ffffffffc0ba81c0

/#PF: supervisor write access in kernel mode

/#PF: error_code(0x0003) - permissions violation

CPU: 33 UID: 0 PID: 1075 Comm: systemd-udevd Not tainted 6.12.0-rc6-00077-g2e1b3cc9d7f7 #1
