AI-suggested
An official patch is available and should be applied to affected Linux kernel versions to resolve the memory leak. Users should update to the fixed kernel versions as provided by their distribution. No additional mitigation is required beyond applying the patch.
Description
A memory leak vulnerability was identified and fixed in the Linux kernel's SCSI lpfc driver, specifically in the lpfc_sli4_driver_resource_setup() function. The issue involved allocated memory for mboxq not being freed on certain early error exit paths. This flaw could lead to resource exhaustion over time but does not indicate direct exploitation or system compromise. The vulnerability affects specific Linux kernel versions and has been addressed with an official patch.
