2) Improper handling of exceptional conditions
EUVDB-ID: #VU79450
Risk: Low
CVSSv4.0: 3.3 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H/E:U/U:Clear]
CVE-ID: CVE-2022-33748
CWE-ID:
CWE-755 - Improper Handling of Exceptional Conditions
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to lock order inversion in transitive grant copy handling As part of XSA-226 a missing cleanup call was inserted on an error handling path. A local user can send specially crafted input and perform a denial of service (DoS) attack.
MitigationUpdate the affected package xen to the latest version.
