XSAs released on 2026-05-12
https://www.qubes-os.org/news/2026/05/13/xsas-released-on-2026-05-12/

The Xen Project (https://xenproject.org/) has released one or more Xen security advisories (XSAs) (https://xenbits.xen.org/xsa/).
The security of Qubes OS is affected.

XSAs that DO affect the security of Qubes OS

The following XSAs do affect the security of Qubes OS:


XSA-490 (https://xenbits.xen.org/xsa/advisory-490.html)

See QSB-113 (https://www.qubes-os.org/news/2026/05/13/qsb-113/)




XSAs that DO NOT affect the security of Qubes OS

The following XSAs do not affect the security of Qubes OS, and no user action is necessary:

About this announcement

Qubes OS uses the Xen hypervisor (https://wiki.xenproject.org/wiki/Xen_Project_Software_Overview) as part of its architecture (https://doc.qubes-os.org/en/latest/developer/system/architecture.html). When the Xen Project (https://xenproject.org/) publicly discloses a vulnerability in the Xen hypervisor, they issue a notice called a Xen security advisory (XSA) (https://xenproject.org/developers/security-policy/). Vulnerabilities in the Xen hypervisor sometimes have security implications for Qubes OS. When they do, we issue a notice called a Qubes security bulletin (QSB) (https://www.qubes-os.org/security/qsb/). (QSBs are also issued for non-Xen vulnerabilities.) However, QSBs can provide only positive confirmation that certain XSAs do affect the security of Qubes OS. QSBs cannot provide negative confirmation that other XSAs do not affect the security of Qubes OS. Therefore, we also maintain an XSA tracker (https://www.qubes-os.org/security/xsa/), which is a comprehensive list of all XSAs publicly disclosed to date, including whether each one affects the security of Qubes OS. When new XSAs are published, we add them to the XSA tracker and publish a notice like this one in order to inform Qubes users that a new batch of XSAs has been released and whether each one affects the security of Qubes OS.
QSB-113: AMD CPU Opcode Cache corruption (XSA-490)
https://www.qubes-os.org/news/2026/05/13/qsb-113/

We have published Qubes Security Bulletin (QSB) 113: AMD CPU Opcode Cache corruption (XSA-490) (https://github.com/QubesOS/qubes-secpack/blob/50c915e8e7423508f973543d038876b43261d315/QSBs/qsb-113-2026.txt). The text of this QSB and its accompanying cryptographic signatures are reproduced below, followed by a general explanation of this announcement and authentication instructions.

Qubes Security Bulletin 113


---===[ Qubes Security Bulletin 113 ]===---

2026-05-12

AMD CPU Opcode Cache corruption (XSA-490)

User action
------------

Continue to update normally [1] in order to receive the security updates
described in the "Patching" section below. No other user action is
required in response to this QSB.

Summary
--------

On 2026-05-12, the Xen Project published XSA-490, "x86: CPU Opcode Cache
corruption" (CVE-2025-54518) [3]:
| AMD have disclosed a potential vulnerability in certain CPUs which can
| cause instructions to execute at a higher privilege.

For more information, see AMD's "CPU OP Cache Corruption" advisory. [4]

Impact
-------

On affected systems, an attacker can attempt to exploit this
vulnerability in order to:
- escalate privileges from userspace to the kernel inside of a given
qube in order to escape sandboxes inside that qube
- compromise Qubes OS itself

Affected systems
-----------------

Only AMD Zen 2 systems are affected. Systems with other AMD
microarchitectures and systems with Intel processors are not affected.

Patching
---------

The following packages contain security updates that address the
vulnerabilities described in this bulletin:

For Qubes 4.2, in dom0:
- Xen packages, version 4.17.6-5
For Qubes 4.3, in dom0:
- Xen packages, version 4.19.4-8

These packages will migrate from the security-testing repository to the
current (stable) repository over the next two weeks after being tested
by the community. [2] Once available, the packages should be installed
via the Qubes Update tool or its command-line equivalents. [1]

Dom0 must be restarted afterward in order for the updates to take
effect.

If you use Anti Evil Maid, you will need to reseal your secret
passphrase to new PCR values, as PCR18+19 will change due to the new Xen
binaries.
