CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 0CVE-2023-3269 – Distros-[dirtyvma] privilege escalation via non-rcu-protected vma traversal
https://notcve.org/view.php?id=CVE-2023-3269
A vulnerability exists in the memory management subsystem of the Linux kernel. The lock handling for accessing and updating virtual memory areas (VMAs) is incorrect, leading to use-after-free problems. This issue can be successfully exploited to execute arbitrary kernel code, escalate containers, and gain root privileges. • http://seclists.org/fulldisclosure/2023/Jul/43 http://www.openwall.com/lists/oss-security/2023/07/28/1 http://www.openwall.com/lists/oss-security/2023/08/25/1 http://www.openwall.com/lists/oss-security/2023/08/25/4 https://access.redhat.com/security/cve/CVE-2023-3269 https://bugzilla.redhat.com/show_bug.cgi?id=2215268 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U6AAA64CUPSMBW6XDTXPQJ3KQWYQ4K7L https://security.netapp.com/advisory • CWE-416: Use After Free •
