AI-suggested
An official patch is available and should be applied to affected Linux kernel versions. The Ubuntu security advisory USN-8096-1 confirms that this and other kernel vulnerabilities have been fixed. Users should update their systems to the patched kernel versions to mitigate this issue.
Description
A vulnerability in the Linux kernel's SCSI target subsystem was resolved where a NULL pointer dereference could occur if allocation of cmd->t_task_cdb failed. In error cases, the pointer was not reset properly, potentially leading to a system crash. This issue affects multiple specific Linux kernel versions and has a CVSS score of 7.5 with a medium severity rating. A patch is available to address this flaw.
