Overview

CVE-2023-52515 is a critical-severity vulnerability. It was published on March 2, 2024 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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

RDMA/srp: Do not call scsi_done() from srp_abort()

After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler

callback, it performs one of the following actions:

* Call scsi_queue_insert().

* Call scsi_finish_command().

* Call scsi_eh_scmd_add().

Hence, SCSI abort handlers must not call scsi_done(). Otherwise all

the above actions would trigger a use-after-free. Hence remove the

scsi_done() call from srp_abort(). Keep the srp_free_req() call

before returning SUCCESS because we may not see the command again if

SUCCESS is returned.

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.
