Description

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 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 [email protected]
