Oracle Linux: CVE-2023-32233: ELSA-2023-3723: kernel security and bug fix update (IMPORTANT) (Multiple Advisories)
Description
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled. A use-after-free vulnerability was found in the Netfilter subsystem of the Linux kernel when processing batch requests to update nf_tables configuration. This vulnerability can be abused to perform arbitrary reads and writes in kernel memory. A local user (with CAP_NET_ADMIN capability) could use this flaw to crash the system or potentially escalate their privileges on the system.
