CVE-2021-47076

CVE-2021-47076 is a Linux kernel vulnerability affecting the RDMA/rxe path. The flaw was due to RXE not updating WQE status on LOCAL_WRITE failures, which could trigger a kernel panic when an atomic operation is sent with an invalid lkey. The issue has concrete remediation in the Linux kernel ups...

CVE-2021-47076 RDMA/rxe: Return CQE error if invalid lkey was supplied
