  3. CVE-2024-56625
In the Linux kernel, the following vulnerability has been resolved: can: dev: can_set_termination(): allow sleeping GPIOs In commit 6e86a1543c37 ("can: dev: provide optional GPIO based termination support") GPIO based termination support was added. For no particular reason that patch uses gpiod_set_value() to set the GPIO. This leads to the following warning, if the systems uses a sleeping GPIO, i.e. behind an I2C port expander: | WARNING: CPU: 0 PID: 379 at /drivers/gpio/gpiolib.c:3496 gpiod_set_value+0x50/0x6c | CPU: 0 UID: 0 PID: 379 Comm: ip Not tainted 6.11.0-20241016-1 #1 823affae360cc91126e4d316d7a614a8bf86236c Replace gpiod_set_value() by gpiod_set_value_cansleep() to allow the use of sleeping GPIOs.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: can: dev: can_set_termination(): permitir GPIO inactivos En el commit 6e86a1543c37 ("can: dev: proporcionar soporte de terminación basado en GPIO opcional") se agregó soporte de terminación basado en GPIO. Sin ninguna razón en particular, ese parche usa gpiod_set_value() para configurar el GPIO. Esto lleva a la siguiente advertencia, si el sistema usa un GPIO inactivo, es decir, detrás de un expansor de puerto I2C: | ADVERTENCIA: CPU: 0 PID: 379 en /drivers/gpio/gpiolib.c:3496 gpiod_set_value+0x50/0x6c | CPU: 0 UID: 0 PID: 379 Comm: ip No contaminado 6.11.0-20241016-1 #1 823affae360cc91126e4d316d7a614a8bf86236c Reemplace gpiod_set_value() por gpiod_set_value_cansleep() para permitir el uso de GPIO inactivos.
