Vulnerability from github – Published: 2024-05-03 15:30 – Updated: 2024-06-03 18:53In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix drain SQ hang with no completion
SW generated completions for outstanding WRs posted on SQ after QP is in error target the wrong CQ. This causes the ib_drain_sq to hang with no completion.
Fix this to generate completions on the right CQ.
