Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A use-after-free issue exists in the RDMA/efa component during admin queue completion handling. When an admin command completes with an error, the system attempts to print data from the completion context. However, this context may have already been freed in the polling or interrupts handler, leading to the processing of data from a context in an unknown state.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
