Description
The vulnerability allows a local user to cause a denial of service, disclose sensitive information, and potentially execute arbitrary code.
The vulnerability exists due to a boundary error in the rocket driver when handling device probe error paths. A local user can trigger improper unwinding during initialization failure to cause out-of-bounds memory accesses.
Exploitation requires loading or probing of the rocket accelerator driver, which may require privileged access to trigger device initialization.
Remediation
Install security update from vendor's repository.
