Root access gives an attacker or administrator complete control of a Unix-like system, allowing changes to data, software, accounts, and security settings.

Background for this topic.
Root access is unrestricted administrative control of a Unix or Linux system. The root account, or an equivalent privilege obtained through mechanisms such as sudo, can read or change nearly any file, alter system configuration, install software, and control running processes. Related uses of “root” may describe equivalent administrator privileges in containers, cloud workloads, network appliances, or mobile devices.
Because root privileges can bypass ordinary access controls, stolen administrative credentials or a vulnerability that enables privilege escalation can let an attacker modify security settings, access protected data, establish persistence, or disrupt the host. Organizations generally reduce exposure by disabling direct root login where practical, using named administrator accounts with least privilege, protecting privileged authentication with strong controls, and recording and reviewing elevation events. Vulnerability management should prioritize flaws that can grant local or remote root-level execution; during an incident, investigators must assess whether root access was obtained and treat the host’s integrity as potentially compromised.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added a recently disclosed security flaw impacting various Linux distributions to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation in the wild
AI-Assisted Offensive Security Researcher Discovered Flaw After 1 Hour of ScanningPatch all Linux kernels issued from 2017 onwards to fix a serious vulnerability in the kernel’s cryptography API that can be easily exploited by a local, unprivileged user to gain root-level access. The major flaw is the latest to be found by an AI-assisted researcher.
An exploit has been published for a local privilege escalation vulnerability dubbed "Copy Fail" that impacts Linux kernels released since 2017, allowing an unprivileged local attacker to gain root permissions. [...]
