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.

CVE-2024-52798 path-to-regexp: path-to-regexp Unpatched `path-to-regexp` ReDoS in 0.1.x
path-to-regexp turns path strings into a regular expressions. In certain cases, path-to-regexp will output a regular expression that can be exploited to cause poor performance. The regular expression that is vulnerable to backtracking can be generated in the 0.1.x release of path-to-regexp. Upgrade to 0.1.12. This vulnerability exists because of an incomplete fix for CVE-2024-45296.

CVE-2024-0775 kernel: use-after-free while changing the mount option in __ext4_remount leading
If there are failures while changing the mount options in __ext4_remount(), we need to restore the old mount options, there is a chance that we will free the old quota file names before a potential failure leading to a use-after-free.
Also, if there is a failed read/write to read-only transition, if the quota has already been suspended, we need to renable quota handling.
