  3. CVE-2024-50109
In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix null ptr dereference in raid10_size() In raid10_run() if raid10_set_queue_limits() succeed, the return value is set to zero, and if following procedures failed raid10_run() will return zero while mddev->private is still NULL, causing null ptr dereference in raid10_size(). Fix the problem by only overwrite the return value if raid10_set_queue_limits() failed.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: md/raid10: se corrige la desreferencia ptr nulo en raid10_size() En raid10_run(), si raid10_set_queue_limits() tiene éxito, el valor de retorno se establece en cero y, si fallan los siguientes procedimientos, raid10_run() devolverá cero mientras que mddev->private sigue siendo NULL, lo que provoca una desreferencia ptr nula en raid10_size(). Solucione el problema sobrescribiendo solo el valor de retorno si raid10_set_queue_limits() falla.
