CWE ID 416
Summary
CVE-2024-1086 is a use-after-free vulnerability impacting the Linux kernel's netfilter: nf_tables component. It allows for local privilege escalation, enabling attackers to exploit the nft_verdict_init() function, which accepts positive values as drop errors within hook verdicts. Consequently, the nf_hook_slow() function can lead to a double free vulnerability when NF_DROP is issued with a drop error resembling NF_ACCEPT. To mitigate this risk, it's recommended to upgrade past commit f342de4e2f33e0e39165d8639387aa6c19dff660.
