CVE-2026-63906

Kernel memory corruption via premature device-node release

Published Jul 19, 2026 · Updated Jul 19, 2026

Use-after-free in the OMAP2430 MUSB driver in Linux Kernel 6.2 allows local users to corrupt kernel memory during platform-device probing. The omap2430_probe() function releases the np device-node reference before later property and IRQ reads, leaving a freed node reachable through the stale pointer. The path executes locally during boot-time OMAP enumeration, module loading, or sysfs binding; memory corruption can crash the kernel or compromise data.
