Linux Kernel up to 6.8.9 privileges assignment

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.8.9. It has been rated as critical. Affected by this issue is an unknown functionality. The manipulation with an unknown input leads to a privileges assignment vulnerability. Using CWE to declare the problem leads to CWE-266. A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: fs/9p: only translate RWX permissions for plain 9P2000 Garbage in plain 9P2000's perm bits is allowed through, which causes it to be able to set (among others) the suid bit. This was presumably not the intent since the unix extended bits are handled explicitly and conditionally on .u.

The advisory is shared for download at git.kernel.org. This vulnerability is handled as CVE-2024-36964 since 05/30/2024. The exploitation is known to be easy. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068.

The vulnerability scanner Nessus provides a plugin with the ID 209089 (SUSE SLES15 Security Update : kernel RT (Live Patch 0 for SLE 15 SP6) (SUSE-SU-2024:3628-1)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 4.19.314, 5.4.276, 5.10.217, 5.15.159, 6.1.91, 6.6.31 or 6.8.10 eliminates this vulnerability.
