PUBLISHED
CVSS 7.800000190734863 HIGH
Record from OSV · Published May 8, 2023
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.
