NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.
