Which Virtualization Host vulnerabilities are being exploited?
4 flaws are on the government list of vulnerabilities known to be exploited. These are the ones criminals are using now, so they go first, whatever their severity score says.
- 7.8Linux Kernel Improper Authentication Vulnerability
Linux Kernel contains an improper authentication vulnerability which could allow for privilege escalation via the cgroups v1 release_agent feature.
- 7.8GNU C Library Buffer Overflow Vulnerability
GNU C Library's dynamic loader ld.so contains a buffer overflow vulnerability when processing the GLIBC_TUNABLES environment variable, allowing a local attacker to execute code with elevated privileges.
- 7.8Red Hat Polkit Incorrect Authorization Vulnerability
Red Hat Polkit contains an incorrect authorization vulnerability through the bypassing of credential checks for D-Bus requests, allowing for privilege escalation.
- 7.8Linux Kernel Privilege Escalation Vulnerability
Linux kernel contains an improper initialization vulnerability where an unprivileged local user could escalate their privileges on the system.
Which Virtualization Host flaws are most likely to be used?
Ranked by the latest exploit-likelihood forecast: the chance each flaw is used in an attack in the next 30 days. A high severity score on its own doesn't tell you that. Flaws shared by many other makers' products are left out.
