kernel: KVM: arm64: Tear down vGIC on failed vCPU creation

A use-after-free flaw was found in KVM for arm64 in the Linux Kernel, if the kvmarchvcpucreate fails to share the vCPU page with the hypervisor. This vulnerability could even lead to a kernel information leak problem...

A week in security (March 23 – March 29)

Last week on Malwarebytes Labs: Criminals are renting virtual phones to bypass bank security Bogus Avast website fakes virus scan, installs Venom Stealer instead Infiniti Stealer: a new macOS infostealer using ClickFix and Python/Nuitka GlassWorm attack installs fake browser extension for...

Study of Post Quantum Status of Widely Used Protocols

The advent of quantum computing poses significant threats to classical public-key cryptographic primitives such as RSA and elliptic-curve cryptography. As many critical network and security protocols depend on these primitives for key exchange and authentication, there is an urgent need to...

GHSA-Q9VP-3WCG-8P4X Incus vulnerable to local privilege escalation through VM screenshot path

Summary Incus provides an API to retrieve VM screenshots, that API relies on the use of a temporary file for QEMU to write the screenshot to which is then picked up and sent to the user prior to deletion. As Incus uses predictable paths under /tmp for this, an attacker with local access to the...

CVE-2021-27007

NetApp Virtual Desktop Service VDS when used with an HTML5 gateway is susceptible to a vulnerability which when successfully exploited could allow an unauthenticated attacker to takeover a Remote Desktop Session...

Criminals are renting virtual phones to bypass bank security

Researchers at Group-IB warn about criminals using virtual Android devices to bypass modern security solutions. Cloud phones are virtual Android devices that can fully mimic real device fingerprints model, hardware, IP, timezone, sensor data, behavior. This allows them to undermine banks’...

CVE-2026-27857

The CVE-2026-27857 issue affects the Dovecot IMAP server where sending a NOOP with 4000+ parentheses causes about 1 MB of memory to be allocated for each connection. Attackers could spawn many connections (potentially from a single IP) to exhaust VSZ and disrupt the service or other proxied conne...

Linux Distros Unpatched Vulnerability : CVE-2025-2509

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Out-of-Bounds Read in Virglrenderer in ChromeOS 16093.57.0 allows a malicious guest VM to achieve arbitrary address access within the crosvm sandboxed process,...

DEBIAN-CVE-2026-33711

Incus is a system container and virtual machine manager. Incus provides an API to retrieve VM screenshots. That API relies on the use of a temporary file for QEMU to write the screenshot to which is then picked up and sent to the user prior to deletion. As versions prior to 6.23.0 use predictable...

CVE-2026-33711

CVE-2026-33711 affects Incus: the VM VGA screenshot path uses a predictable /tmp file (incus_screenshot_). If an attacker has local access and kernel protected_symlinks is disabled, they can pre-place symlinks to point to host files, cause truncation and ownership changes via the QEMU screenshot ...
