Both privilege escalation vulnerabilities stem from bugs in the kernel’s handling of page caches stored in memory, allowing untrusted users to modify them. They target caches in networking and memory-fragment handling components. Specifically, CVE-2026-43284 attacks the esp4 and esp6 () processes, and CVE-2026-43500 zeroes in on rxrpc. Last week’s CopyFail exploited faulty page caching in… Read More »
Publicly released exploit code for an effectively unpatched vulnerability that gives root access to virtually all releases of Linux is setting off alarm bells as defenders scramble to ward off severe compromises inside data centers and on personal devices. The vulnerability and exploit code that exploits it were released Wednesday evening by researchers from security… Read More »
Coruna is also notable for its use by three distinct hacking groups. Google first detected its use in February of last year in an operation conducted by a “customer of a surveillance vendor.” The vulnerability exploited, tracked as CVE-2025-23222, had been patched 13 months earlier. In July 2025, a “suspected Russian espionage group” exploited CVE-2023-43000… Read More »
