Overview

CVE-2024-41087 is a high-severity vulnerability. It was published on July 29, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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 double free on error

If e.g. the ata_port_alloc() call in ata_host_alloc() fails, we will jump

to the err_out label, which will call devres_release_group().

devres_release_group() will trigger a call to ata_host_release().

ata_host_release() calls kfree(host), so executing the kfree(host) in

ata_host_alloc() will lead to a double free:
