CVE-2021-47436

A flaw was found in the Linux kernel's MUSB DSPS driver. Incomplete cleanup during device initialization failure leaves an allocated platform device unregistered in the system. A local user could exploit this flaw to cause a NULL pointer dereference, leading to a system crash and a Denial of Service (DoS).

This vulnerability is rated as Low severity for Red Hat products because exploitation requires specialized embedded hardware, restricting the blast radius to non-standard environments with no remote vector. The flaw stems from an improper probe cleanup sequence in the Texas Instruments MUSB controller subsystem, which can trigger a kernel panic during boot. Standard enterprise installations do not typically configure or use this driver by default, substantially mitigating the risk.
