NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-modules-internal package and not the kernel-rt-modules-internal package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

A heap out-of-bounds write vulnerability was found in the Linux kernel's RPC-over-RDMA server reply path in net/sunrpc/xprtrdma/svc_rdma_sendto.c. When a crafted RPC-over-RDMA client sends a large NFS READ request with an empty Write list and no Reply chunk, the server linearizes the entire multi-page reply into a fixed-size 4096-byte heap buffer without bounds checking, resulting in a kernel heap overflow. This can lead to denial of service via kernel crash or potential code execution through corruption of adjacent kernel heap objects.
