Advisory Updated Date: 2023-06-06 18:36 Pacific
Severity:
Important
Issue Overview:
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. (CVE-2023-32233)
Affected Packages:
kernel
Issue Correction:
Run yum update kernel to update your system.
