Summary: Several security issues were fixed in the Linux kernel.
Jan Beulich discovered that the Xen netback backend in the Linux kernel did
not properly handle certain error conditions under paravirtualization. An
attacker in a guest VM could possibly use this to cause a denial of service

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

kernel: fuse: stall on CPU can occur because a retry loop continually finds the same bad inode
An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A "stall on CPU" can occur because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1.
A denial of service in the kernel side of the FUSE functionality can allow a local system to create a denial of service.
Mitigation: As the FUSE module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions:
# echo "install fuse /bin/true" >> /etc/modprobe.d/disable-fuse.conf
The system will need to be restarted if the FUSE modules are loaded. In most circumstances, the CIFS kernel modules will be unable to be unloaded while the FUSE fil
