Virtualization vulnerabilitiesAnd the versions its exploited flaws hit.
Virtualization is made by Red Hat. We track 128 published vulnerabilities listed under that exact name, across 11 versions. 5 of them are on the list of flaws known to be exploited, the newest added on 21 November 2023. Red Hat lists newer releases under their own names, such as Virtualization Host, so check those pages too.
The most recent Virtualization flaw added to the known-exploited list is CVE-2023-4911, on 21 November 2023. We keep watching the known-exploited list.
Is Virtualization listed under other names? Yes.
Red Hat also lists Virtualization under more specific names, such as Virtualization Host and Virtualization Manager. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.

Which versions of Virtualization do the exploited flaws hit?
Each exploited flaw lists the versions it affects, as published by the vendor. Find your version, then patch.
Which Virtualization vulnerabilities are being exploited?
5 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.
- 7.8GNU 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.
- 7.5OpenSSL Information Disclosure Vulnerability
The TLS and DTLS implementations in OpenSSL do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information.
- 9.8GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute code.
- 9.8GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute code.
Which Virtualization 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.

- 71%CVE-2018-5390High
Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service.
- 68%CVE-2022-0435High
A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
- 64%
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable.
- 64%CVE-2019-14287High
In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID.
- 61%CVE-2018-3639Medium
