High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.58
Description
The issue is related to a double free in the driver API
bus register() function. This occurs when an error happens after kset register(), causing @priv to be freed twice. The problem is fixed by setting @priv to NULL after the first free. This vulnerability may allow an attacker to impact the confidentiality, integrity, and availability of protected information.Recommendations
For Linux kernel versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue. As a temporary workaround, consider restricting access to the
bus register() function until a patch is available.Exploit
