CVE-2024-53175

Memory exhaustion via failed IPC namespace cleanup

Published Dec 27, 2024 · Updated May 11, 2026

Memory leak in affected Linux kernel revisions allows local users to exhaust kernel memory through failed IPC namespace creation. The create_ipc_ns error path skips retire_ipc_sysctls after msg_init_ns fails, leaving IPC and message-queue sysctl allocations referenced. Repeated namespace creation under memory pressure is required, and the bounded consequence is availability loss through unreclaimed kernel memory.
