CVE-2023-5197

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free.

We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
