Threats tagged 'ghsa-wqhx-qpfw-hj6x'

A use-after-free vulnerability exists in the Linux kernel's RDMA/rvt subsystem due to improper handling of port allocation failure. The function rvt_alloc_device() deallocates the device but returns a pointer to the freed memory, causing callers to dereference an invalid pointer. This issue has been resolved by returning NULL immediately after deallocation to signal allocation failure.
