CVE-2024-50065

Local denial of service via sleeping allocation

Published Oct 21, 2024 · Updated May 23, 2026

Denial of service in the Linux kernel ntfs3 driver allows local users to interrupt an affected system through pathname lookup under memory pressure. ntfs_d_hash calls __get_name, which allocates with GFP_KERNEL and can sleep during RCU-walk instead of using a nonblocking allocation. Reachability requires local access, ntfs3 pathname processing, and memory pressure; the published impact is limited to availability.
