If the item was from the pre-allocated\npool, calling kfree() on it is a bug that can lead to memory corruption.\n\nFix this by using the correct deallocation function,\nqla24xx_free_purex_item(), which properly handles both dynamically\nallocated and pre-allocated items.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
