Overview

CVE-2022-49217 is a medium-severity vulnerability. It was published on February 26, 2025 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:

scsi: pm8001: Fix abort all task initialization

In pm80xx_send_abort_all(), the n_elem field of the ccb used is not

initialized to 0. This missing initialization sometimes lead to the task

completion path seeing the ccb with a non-zero n_elem resulting in the

execution of invalid dma_unmap_sg() calls in pm8001_ccb_task_free(),

causing a crash such as:
