drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.
A use-after-free flaw was found in drivers/block/floppy.c in floppy drive in the Linux Kernel. This issue could allow a local attacker to crash the system due to a race problem between raw_cmd_ioctl and seek_interrupt, which can lead to a kernel information leak.
Statement: This issue does not affect RHEL 8 and 9 Kernel releases, as the config option CONFIG_BLK_DEV_FD is not enabled, therefore, they are marked as not-affected.

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
