A critical vulnerability (CVSS 10.0) in Canonical’s LXD and MicroCloud allows attackers to impersonate trusted clients without possessing the client’s private key, provided they can access the HTTPS API over the internet ^[1].
A recently patched Android vulnerability, CVE-2026-58882 and dubbed “SMS of Death,” can be exploited to remotely crash unpatched devices by sending a specially crafted SMS message. A proof-of-concept exploit has been released ^[7].
