- Summary
- RDMA/rvt: Return NULL after port allocation failure
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rvt: Return NULL after port allocation failure
rvt_alloc_device() deallocates the IB device when its port array cannot be allocated but then returns the pointer to the released allocation. Callers treat any non-NULL value as valid and dereference it, resulting in a use-after-free.
Return NULL immediately after deallocation so callers can propagate the allocation failure.
