Description OSIDB Bzimport 2025-02-26 03:15:59 UTC 
In the Linux kernel, the following vulnerability has been resolved:

SUNRPC: Trap RDMA segment overflows

Prevent svc_rdma_build_writes() from walking off the end of a Write
chunk's segment array. Caught with KASAN.

The test that this fix replaces is invalid, and might have been left
over from an earlier prototype of the PCL work.
