CVE-2024-53077

Local denial of service via rpcrdma memory leak

Published Nov 19, 2024 · Updated May 11, 2026

Memory leak in Linux 6.11 through 6.11.6 allows local users to interrupt service by exhausting kernel memory during rpcrdma teardown. rpcrdma_add_one() initializes an xarray that can accrue nodes, but rpcrdma_remove_one() omitted the matching xa_destroy() before releasing the device. Exploitation requires local low-privileged access and repeated reachability of rpcrdma device teardown; the resulting resource exhaustion interrupts system availability.
