**Name of the Vulnerable Software and Affected Versions** Safari versions prior to 16.6 watchOS versions prior to 9.6 iOS versions prior to 15.7.8 and prior to 16.6 iPadOS versions prior to 15.7.8 and prior to 16.6 tvOS versions prior to 16.6 macOS Ventura versions prior to 13.5 **Description** A logic issue was addressed with improved state management, which may allow a website to track sensitive user information. This issue is related to the WebKitGTK and WPE WebKit modules, and its exploitation can lead to the disclosure of protected information. **Recommendations** For Safari versions prior to 16.6, update to Safari 16.6 or later. For watchOS versions prior to 9.6, update to watchOS 9.6 or later. For iOS versions prior to 15.7.8, update to iOS 15.7.8 or later. For iOS versions prior to 16.6, update to iOS 16.6 or later. For iPadOS versions prior to 15.7.8, update to iPadOS 15.7.8 or later. For iPadOS versions prior to 16.6, update to iPadOS 16.6 or later. For tvOS versions prior to 16.6, update to tvOS 16.6 or later. For macOS Ventura versions prior to 13.5, update to macOS Ventura 13.5 or later.

**Name of the Vulnerable Software and Affected Versions** Intel(R) Processors (affected versions not specified) **Description** The issue is related to cleanup errors in some Intel(R) processors, which may allow an authenticated user to potentially enable information disclosure via local access. This is connected to a leak in the store buffer of results from reading vector registers, which are modified during the execution of vector instructions. An attacker could exploit this to disclose protected information. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Intel(R) Processors (affected versions not specified) **Description** The issue is related to cleanup errors in some data cache evictions for some Intel(R) Processors, which may allow an authenticated user to potentially enable information disclosure via local access. This is caused by a data leak from the L1D cache. The vulnerability can be exploited to disclose protected information. Researchers have found a new speculative execution vulnerability in Intel CPUs that could let attackers leak targeted sensitive data from the OS kernel, co-resident virtual machines, and even from Intel's secured SGX enclave. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Intel microprocessors (affected versions not specified) vCenter Server (affected versions not specified) ESXi (affected versions not specified) Workstation (affected versions not specified) Fusion (affected versions not specified) **Description** The issue is related to Microarchitectural Data Sampling Uncacheable Memory (MDSUM) on some microprocessors that utilize speculative execution. This may allow an authenticated user with local access to potentially enable information disclosure via a side channel. An attacker with local access to a targeted system may exploit this issue to obtain data on the targeted system, causing some information leakage. **Recommendations** For Intel microprocessors, apply the microcode updates as guided by Intel. For vCenter Server, update to a version that includes Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For ESXi, update to a version that includes Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For Workstation, update to a version that includes Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For Fusion, update to a version that includes Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities.

**Name of the Vulnerable Software and Affected Versions** Intel microprocessors (affected versions not specified) vCenter Server (affected versions not specified) ESXi (affected versions not specified) Workstation (affected versions not specified) Fusion (affected versions not specified) Huawei VRP (affected versions not specified) **Description** The issue is related to Microarchitectural Load Port Data Sampling (MLPDS), which may allow an authenticated user to potentially enable information disclosure via a side channel with local access. This is due to the incorrect implementation of saving outdated operation results in the load port table. The exploitation of this issue can allow an attacker to access confidential information. **Recommendations** For Intel microprocessors, at the moment, there is no information about a newer version that contains a fix for this vulnerability. For vCenter Server, apply Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For ESXi, apply Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For Workstation, apply Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For Fusion, apply Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For Huawei VRP, at the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Intel Microprocessors (affected versions not specified) vCenter Server (affected versions not specified) ESXi (affected versions not specified) Workstation (affected versions not specified) Fusion (affected versions not specified) **Description** The issue is related to Microarchitectural Fill Buffer Data Sampling (MFBDS), which may allow an authenticated user to potentially enable information disclosure via a side channel with local access. This is due to the speculative execution utilized by some microprocessors. **Recommendations** For Intel Microprocessors, consider applying the microcode updates as guided by Intel to mitigate the risk. For vCenter Server, update to a version that includes Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For ESXi, update to a version that includes Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For Workstation, update to a version that includes Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities. For Fusion, update to a version that includes Hypervisor-Specific Mitigations for MDS speculative execution vulnerabilities.
