In the Linux kernel, the following vulnerability has been resolved:
gpiolib: cdev: fix uninitialised kfifo
If a line is requested with debounce, and that results in debouncing
in software, and the line is subsequently reconfigured to enable edge
detection then the allocation of the kfifo to contain edge events is
overlooked. This results in events being written to and read from an
uninitialised kfifo. Read events are returned to userspace.
Initialise the kfifo in the case where the software debounce is
already active.

Summary: Several security issues were fixed in the Linux kernel.
Maxim Suhanov discovered that the NTFS file system implementation in the
Linux kernel did not properly validate file name length in certain
situations, leading to an out-of-bounds read. An attacker could use this to
construct a malicious NTFS image that, when mounted and operated on, could
expose sensitive information (kernel memory). (CVE-2023-45896)
It was discovered that some AMD processors did not properly clear data in
the floating point divider unit during speculative execution. A local

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 to reflect this.
