Descriptions
In the Linux kernel, the following vulnerability has been resolved:
eeprom: at24: fix memory corruption race condition
If the eeprom is not accessible, an nvmem device will be registered, the
read will fail, and the device will be torn down. If another driver
accesses the nvmem device after the teardown, it will reference
invalid memory.
Move the failure point before registering the nvmem device.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: eeprom: at24: corrige la condición de ejecución por corrupción de memoria. Si no se puede acceder a la eeprom, se registrará un dispositivo nvmem, la lectura fallará y el dispositivo se apagará. Si otro controlador accede al dispositivo nvmem después del desmontaje, hará referencia a una memoria no válida. Mueva el punto de fallo antes de registrar el dispositivo nvmem.
CVE-2024-35848 is a vulnerability in the Linux kernel's EEPROM driver (at24) that can lead to memory corruption. The issue arises when an EEPROM device is inaccessible: the system registers an nvmem device, the read operation fails, and the device is subsequently torn down. If another driver attempts to access the nvmem device after this teardown, it may reference invalid memory, causing potential system instability. The problem has been resolved by adjusting the failure handling to occur before the nvmem device is registered, preventing access to invalid memory. Users should update their Linux kernel to a version that includes this fix to ensure system reliability.
