CVE-2024-56671

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-56671
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 Hardware name: Intel Corporation Kaseyville RP/Kaseyville RP, BIOS KVLDCRB1.PGS.0026.D73.2410081258 10/08/2024 RIP: 0010:gnr_gpio_probe+0x171/0x220 [gpio_graniterapids]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: gpio: graniterapids: Corregir fallo del controlador vGPIO Mover la configuración irq_chip.name de la función probe() a la inicialización de la estructura "irq_chip" para corregir el fallo del controlador vGPIO durante el arranque. El fallo fue causado por una modificación no autorizada del campo irq_chip.name donde la estructura irq_chip se inicializó como const. Este comportamiento es una consecuencia de la implementación subóptima de gpio_irq_chip_set_chip(), que debería cambiarse para evitar descartar el calificador const. Registro de fallos: ERROR: no se puede gestionar el error de página para la dirección: ffffffffc0ba81c0 /#PF: acceso de escritura del supervisor en modo kernel /#PF: error_code(0x0003) - violación de permisos CPU: 33 UID: 0 PID: 1075 Comm: systemd-udevd No contaminado 6.12.0-rc6-00077-g2e1b3cc9d7f7 #1 Nombre del hardware: Intel Corporation Kaseyville RP/Kaseyville RP, BIOS KVLDCRB1.PGS.0026.D73.2410081258 10/08/2024 RIP: 0010:gnr_gpio_probe+0x171/0x220 [gpio_graniterapids]
