  3. CVE-2024-35883
In the Linux kernel, the following vulnerability has been resolved: spi: mchp-pci1xxx: Fix a possible null pointer dereference in pci1xxx_spi_probe In function pci1xxxx_spi_probe, there is a potential null pointer that may be caused by a failed memory allocation by the function devm_kzalloc. Hence, a null pointer check needs to be added to prevent null pointer dereferencing later in the code. To fix this issue, spi_bus->spi_int[iter] should be checked. The memory allocated by devm_kzalloc will be automatically released, so just directly return -ENOMEM without worrying about memory leaks.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: spi: mchp-pci1xxx: corrige una posible desreferencia de puntero null en pci1xxx_spi_probe En la función pci1xxxx_spi_probe, existe un posible puntero null que puede deberse a una asignación de memoria fallida por parte de la función devm_kzalloc. Por lo tanto, es necesario agregar una verificación de puntero null para evitar que se elimine la referencia al puntero null más adelante en el código. Para solucionar este problema, se debe marcar spi_bus->spi_int[iter]. La memoria asignada por devm_kzalloc se liberará automáticamente, por lo que simplemente devuelva -ENOMEM directamente sin preocuparse por pérdidas de memoria.
