Overview

CVE-2024-41098 is a medium-severity vulnerability. It was published on July 29, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

ata: libata-core: Fix null pointer dereference on error

If the ata_port_alloc() call in ata_host_alloc() fails,

ata_host_release() will get called.

However, the code in ata_host_release() tries to free ata_port struct

members unconditionally, which can lead to the following:
