Answer in brief
CVE-2024-1086 records a High severity vulnerability in Use-after-free in Linux kernel's netfilter: nf_tables component. The current sources mark it as known exploited. The current feed maps Linux/Kernel (generic), linux/linux_kernel (generic). Check affected ranges and fixed versions before updating.

A CVSS score is not reported in the current record. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.

Evidence: source:kev:kev:kev:recordA 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.
