Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU83162
Risk: Medium
CVSSv3.1: 4.4 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-46835
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote guest to gain access to sensitive information.
The vulnerability exists due to improperly imposed security restrictions caused by a mismatch in IOMMU quarantine page table levels. A device in quarantine mode can access data from previous quarantine page table usages, possibly leaking data used by previous domains that also had the device assigned.
Update the affected package xen to the latest version.

EUVDB-ID: #VU83163
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-46836
CWE-ID:
CWE-254 - Security Features
Exploit availability: No
DescriptionThe vulnerability allows a remote guest to bypass implemented security restrictions.
The vulnerability exists due to improper implementation of mitigations against BTC/SRSO. A malicious guest can bypass BTC/SRSO protections and launch a BTC/SRSO attack against Xen, which can result in memory access to other guests.
Update the affected package xen to the latest version.
