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.
FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE

kernel: leak of sensitive information due to uninitialized data in stex_queuecommand_lck() in drivers/scsi/stex.c
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.
An information disclosure vulnerability is found in stex_queuecommand_lck() in drivers/scsi/stex.c in the Linux Kernel. This flaw allows a local attacker to disclose sensitive information such as kernel space address.
Mitigation: To mitigate this issue, skip loading the affected module "stex" onto the system until we have a fix available. This can be done using a blacklist mechanism, which will ensure that the driver is not loaded at the boot time.
