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 (affected versions not specified)
Description
The issue is related to the Linux kernel's futex implementation, which involves the use of memory after it has been freed. This could allow an attacker to corrupt system memory, escalate privileges, or impact the confidentiality, integrity, and availability of protected information. The threat is highest for local attackers who can create a futex on a filesystem that is about to be unmounted. Exploitation can lead to local escalation of privilege without needing additional execution privileges, and user interaction is not required.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
