CVE-2022-49253

Service interruption via leaked I2C probe client

Published Feb 26, 2025 · Updated May 11, 2026

Memory leak in the Linux kernel's go7007 Sensoray 2250/2251 driver allows local users to interrupt service through failed probes. The s2250_probe error path returns after control-handler setup fails without unregistering the previously created audio I2C client, leaving its allocation alive. Reachability requires the affected driver and hardware plus local access capable of retriggering the failing probe; accumulated leaks can exhaust kernel memory.
