CVE-2024-47732

In the Linux kernel, the following vulnerability has been resolved: crypto: iaa - Fix potential use after free bug The free_device_compression_mode(iaa_device, device_mode) function frees "device_mode" but it iss passed to iaa_compression_modes[i]->free() a few lines later resulting in a use after free. The good news is that, so far as I can tell, nothing implements the ->free() function and the use after free happens in dead code. But, with this fix, when something does implement it, we'll be ready. :)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: crypto: iaa - Fix potential use after free bug La función free_device_compression_mode(iaa_device, device_mode) libera "device_mode" pero se pasa a iaa_compression_modes[i]->free() unas líneas más adelante, lo que da como resultado un use after free. La buena noticia es que, hasta donde puedo decir, nada implementa la función ->free() y el use after free ocurre en código muerto. Pero, con esta solución, cuando algo la implemente, estaremos listos. :)
