If a user makes the ioctl call for the fastrpc_internal_mmap with the global map flag, fd, and va corresponding to some map already present in the process-specific list, then this map present in the process- specific list could be added to the global list. Because global maps are also searched in the process-specific list. If a map gets removed from the global list and another concurrent thread is using the same map for a process-specific use case, it could lead to a use-after-free. Avoid searching the global map in the process-specific list. Change-Id: I59c820eb984945d39cd6e4b163307ea43ee4d2f4 Signed-off-by: Abhishek Singh <quic_abhishes@quicinc.com>
