CVE-2024-53094

Service interruption via unchecked slab-page splicing

Published Nov 21, 2024 · Updated Aug 5, 2026

Improper page handling in affected Linux kernel releases allows local users to interrupt service through the iSER-over-SIW transmit path. The SIW driver sets MSG_SPLICE_PAGES without first calling sendpage_ok(), allowing skb_splice_from_iter() to receive a slab page that send_page must not process. Exposure requires an iSER initiator operating over SIW, and the published trace demonstrates a kernel warning rather than arbitrary code execution.
