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 classified as critical was found in Linux Kernel up to 6.12.1. This vulnerability affects the function hns_roce_map_mr_sg of the component RDMA. The manipulation of the argument sg_offset with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix NULL pointer derefernce in hns_roce_map_mr_sg() ib_map_mr_sg() allows ULPs to specify NULL as the sg_offset argument. The driver needs to check whether it is a NULL pointer before dereferencing it.

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2024-53226 since 11/19/2024. There are known technical details, but no exploit is available.
