Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a data race condition within the RDMA/irdma subsystem, specifically related to the completion queue pair (CQP) request done memory location. Kernel Concurrency Sanitizer (KCSAN) detected this race while accessing the
cqp request->request done memory location locklessly in irdma handle cqp op while it was being updated in irdma cqp ce handler. The issue is addressed by annotating lockless intent with READ ONCE/WRITE ONCE to prevent compiler optimizations that could trigger the data race. The call stack indicates the issue occurs during device unregistration and module unloading. The functions involved include irdma cqp ce handler, irdma wait event, irdma handle cqp op, and irdma cqp cq destroy cmd.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
