Overview

CVE-2024-57875 is a high-severity vulnerability. It was published on January 11, 2025 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:

block: RCU protect disk->conv_zones_bitmap

Ensure that a disk revalidation changing the conventional zones bitmap

of a disk does not cause invalid memory references when using the

disk_zone_is_conv() helper by RCU protecting the disk->conv_zones_bitmap

pointer.

disk_zone_is_conv() is modified to operate under the RCU read lock and

the function disk_set_conv_zones_bitmap() is added to update a disk

conv_zones_bitmap pointer using rcu_replace_pointer() with the disk

zone_wplugs_lock spinlock held.

disk_free_zone_resources() is modified to call

disk_update_zone_resources() with a NULL bitmap pointer to free the disk

conv_zones_bitmap. disk_set_conv_zones_bitmap() is also used in

disk_update_zone_resources() to set the new (revalidated) bitmap and

free the old one.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
