A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism.

FAQ: Windows 11, version 24H2 is not generally available yet. Why are there updates for this version of Windows listed in the Security Updates table?
The new Copilot+ devices that are now publicly available come with Windows 11, version 24H2 installed. Customers with these devices need to know about any vulnerabilities that affect their machine and to install the updates if they are not receiving automatic updates. Note that the general availability date for Windows 11, version 24H2 is scheduled for later this year.

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.

Microsoft fixes Linux boot issues on dual-boot Windows systems

[HIGH] Microsoft fixes Linux boot issues on dual-boot Windows systems
## Microsoft fixes Linux boot issues on dual-boot Windows systems
## Sergiu Gatlan
Microsoft has fixed a known issue preventing Linux from booting on dual-boot systems with Secure Boot enabled after installing the August 2024 Windows security updates.
The list of affected systems includes those running client (Windows 10 and Windows 11) and server (Windows Server 2012 and later) OS versions.
This issue is triggered by a Secure Boot Advanced Targeting (SBAT) update that blocks UEFI shim bootloaders vulnerable to exploits targeting the CVE-2022-2601 GRUB2 Secure Boot bypass.
While Microsoft said in the CVE-2022-2601 advisory that this SBAT update would not be delivered to devices where dual booting is detected, it also acknowledged that the dual-boot detection failed to detect some cust

## Sergiu Gatlan
Those affected said that their systems (running a wide range of distros, including but not limited to Ubuntu, Linux Mint, Zorin OS, and Puppy Linux) stopped booting into Linux after installing this month's Windows cumulative updates.
The issue is triggered by a Secure Boot Advanced Targeting (SBAT) update designed to block UEFI shim bootloaders vulnerable to exploits targeting the CVE-2022-2601 GRUB2 Secure Boot bypass. When it released the update, Microsoft said the update would not be delivered to devices where dual booting is detected.
However, after acknowledging the issue this week, it also confirmed that "the dual-boot detection did not detect some customized methods of dual-booting and appli
