2) Resource management error
EUVDB-ID: #VU22704
Risk: Low
CVSSv4.0: 4.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2019-11135
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the TSX Asynchronous Abort (TAA) in Intel CPUs. The TAA condition, on some microprocessors utilizing speculative execution, may allow an authenticated user to potentially enable information disclosure via a side channel.
