Description

This security bulletin contains information about 2 vulnerabilities.


1) Information exposure through microarchitectural state after transient execution (CVE-ID: CVE-2024-36349)

CWE-ID: CWE-1342 - Information Exposure through Microarchitectural State after Transient Execution

CVSSv4: CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to information leak. A local user process can infer TSC_AUX even when such a read is disabled, potentially resulting in information leakage.


2) Information exposure through microarchitectural state after transient execution (CVE-ID: CVE-2024-36348)

CWE-ID: CWE-1342 - Information Exposure through Microarchitectural State after Transient Execution

CVSSv4: CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to information leak. A local user process can infer the control registers speculatively even if UMIP[3] feature is enabled, potentially resulting in information leakage.
