Linux Kernel up to 6.7.6 nf_tables privilege escalation

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 6.7.6. It has been declared as problematic. Affected by this vulnerability is an unknown code of the component nf_tables. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: set dormant flag on hook register failure We need to set the dormant flag again if we fail to register the hooks. During memory pressure hook registration can fail and we end up with a table marked as active but no registered hooks. On table/base chain deletion, nf_tables will attempt to unregister the hook again which yields a warn splat from the nftables core.
