| Out-of-bounds read in Capability Access Management Service (camsvc) allows an unauthorized attacker to disclose information locally. |
| Use after free in Windows Clipboard Server allows an unauthorized attacker to elevate privileges locally. |
| Generation of error message containing sensitive information in Windows Kernel allows an authorized attacker to disclose information locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Graphics Kernel allows an authorized attacker to elevate privileges locally. |
| Time-of-check time-of-use (toctou) race condition in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Protection mechanism failure in Windows Remote Assistance allows an unauthorized attacker to bypass a security feature locally. |
| Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an authorized attacker to disclose information locally. |
| Windows Secure Boot stores Microsoft certificates in the UEFI KEK and DB. These original certificates are approaching expiration, and devices containing affected certificate versions must update them to maintain Secure Boot functionality and avoid compromising security by losing security fixes related to Windows boot manager or Secure Boot.
The operating system’s certificate update protection mechanism relies on firmware components that might contain defects, which can cause certificate trust updates to fail or behave unpredictably. This leads to potential disruption of the Secure Boot trust chain and requires careful validation and deployment to restore intended security guarantees.

| Use of uninitialized resource in Dynamic Root of Trust for Measurement (DRTM) allows an authorized attacker to disclose information locally. |
| Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an unauthorized attacker to perform spoofing over a network. |
| In IGEL OS before 11, Secure Boot can be bypassed because the igel-flash-driver module improperly verifies a cryptographic signature. Ultimately, a crafted root filesystem can be mounted from an unverified SquashFS image. |
| Use after free in Microsoft Brokering File System allows an unauthorized attacker to elevate privileges locally. |
| Use after free in Windows Device Association Broker service allows an authorized attacker to elevate privileges locally. |
| Microsoft is aware of vulnerabilities in the third party Agere Modem driver that ships natively with supported Windows operating systems. This is an announcement of the upcoming removal of ltmdm64.sys driver. The driver has been removed in the October cumulative update.
Fax modem hardware dependent on this specific driver will no longer work on Windows.
Microsoft recommends removing any existing dependencies on this hardware. |
