Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
David Bouman discovered that the netfilter subsystem in the Linux kernel
did not properly validate passed user register indices. A local attacker
could use this to cause a denial of service or possibly execute arbitrary
code. (CVE-2022-1015)
Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver

physically proximate attacker could use this to cause a denial of service
(system crash). (CVE-2021-43976)

CVE-2022-26878 [MEDIUM] CWE-401 kernel: Memory leak in Linux VirtIO Bluetooth driver
kernel: Memory leak in Linux VirtIO Bluetooth driver
drivers/bluetooth/virtio_bt.c in the Linux kernel before 5.16.3 has a memory leak (socket buffers have memory allocated but not freed).
A memory leak problem was found in the virtbt_rx_handle in drivers/bluetooth/virtio_bt.c in the Linux kernel. This flaw allows a local attacker to cause a denial of service on the reception of packets with an invalid packet type.
Statement: There was no shipped kernel version that was seen affected by this problem.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

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.
