Description

NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager (nvidia.ko), where it may lead to a use-after-free, which in turn may cause denial of service. This attack is complex to carry out because the attacker needs to have control over freeing some host side resources out of sequence, which requires elevated privileges.

• CWE-416Use After FreeThe product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
