CVE-2024-56671

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> gpio: graniterapids: Fix vGPIO driver crash<br /> <br /> Move setting irq_chip.name from probe() function to the initialization<br /> of "irq_chip" struct in order to fix vGPIO driver crash during bootup.<br /> <br /> Crash was caused by unauthorized modification of irq_chip.name field<br /> where irq_chip struct was initialized as const.<br /> <br /> This behavior is a consequence of suboptimal implementation of<br /> gpio_irq_chip_set_chip(), which should be changed to avoid<br /> casting away const qualifier.<br /> <br /> Crash log:<br /> BUG: unable to handle page fault for address: ffffffffc0ba81c0<br /> /#PF: supervisor write access in kernel mode<br /> /#PF: error_code(0x0003) - permissions violation<br /> CPU: 33 UID: 0 PID: 1075 Comm: systemd-udevd Not tainted 6.12.0-rc6-00077-g2e1b3cc9d7f7 #1<br /> Hardware name: Intel Corporation Kaseyville RP/Kaseyville RP, BIOS KVLDCRB1.PGS.0026.D73.2410081258 10/08/2024<br /> RIP: 0010:gnr_gpio_probe+0x171/0x220 [gpio_graniterapids]
