squashfs filesystem implementation of U-Boot versions from v2020.10-rc2 to v2022.07-rc5 contains a heap-based buffer overflow vulnerability due to a defect in the metadata reading process. Loading a specially crafted squashfs image may lead to a denial-of-service (DoS) condition or arbitrary code execution.

CVE-2022-30767 [HIGH] U-Boot vulnerabilities
Title: U-Boot vulnerabilities
Summary: Several security issues were fixed in u-boot.
It was discovered that U-Boot incorrectly handled certain USB DFU download
setup packets. A local attacker could use this issue to cause U-Boot to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2022-2347)
Nicolas Bidron and Nicolas Guigo discovered that U-Boot incorrectly handled
certain fragmented IP packets. A local attacker could use this issue to
cause U-Boot to crash, resulting in a denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 18.04 LTS, Ubuntu
20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-30552, CVE-2022-30790)
It was discovered that U-Boot incorrectly handled certain NFS lookup
replies. A remote attacker could use this iss

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.
