Notas
This vulnerability affects a common open-source component, third-party library, or a protocol used by different products. Please check with specific vendors for information on patching status. For more information, please see: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f342de4e2f33e0e39165d8639387aa6c19dff660; https://nvd.nist.gov/vuln/detail/CVE-2024-1086
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.
