NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k-debug package and not the kernel-rt-64k-debug package as distributed by Centos.

In the Linux kernel, the following vulnerability has been resolved:

RDMA/siw: Fix immediate work request flush to completion queue

Correctly set send queue element opcode during immediate work request flushing in post sendqueue operation, if the QP is in ERROR state. An undefined ocode value results in out-of-bounds access to an array for mapping the opcode between siw internal and RDMA core representation in work completion generation. It resulted in a KASAN BUG report of type 'global-out-of-bounds' during NFSoRDMA testing.

This patch further fixes a potential case of a malicious user which may write undefined values for completion queue elements status or opcode, if the CQ is memory mapped to user land. It avoids the same out-of-bounds access to arrays for status and opcode mapping as described above.
