Upgrade github.com/siderolabs/talos to 1.2.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/siderolabs/talos

How to Check if You Are Affected

To determine whether your application is affected by GHSA-jr8j-2jhp-m67v, inspect your project dependencies for Github.com/siderolabs/talos:

inspect dependencies for github.com/siderolabs/talos

Analyze the terminal output to locate any version of Github.com/siderolabs/talos in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.0), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Github.com/siderolabs/talos, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel. A denial of service can occur upon binding to an already bound chain. Affected by this vulnerability is the function nft_verdict_init of the file net/netfilter/nf_tables_api.c. The manipulation with an unknown input leads to a denial of service vulnerability. The program does not release or incorrectly releases a resource before it is made available for re-use. ### Patches The fix has been backported to [5.15.64](https://www.linuxkernelcves.com/cves/CVE-2022-39190) version of the upstream Linux kernel (5.15 is the upstream Kernel long term version Talos ships with). Talos >= v1.2.0 is shipped with Linux Kernel 5.15.64 fixing the above issue. ### Workarounds It's recommended to upgrade ### References - https://www.sesin.at/2022/09/02/cve-2022-39190-linux-kernel-up-to-5-19-5-nf_tables_api-c-nft_verdict_init-denial-of-service/ - https://nvd.nist.gov/vuln/detail/CVE-2022-39190 ### For more information - Email us at [security@siderolabs.com](mailto:security@siderolabs.com)
