CVE-2024-1086 Root Cause & Exploitation Target kernels: Linux 6.8 netfilter nftables Novel angle: Logic confusion in nftverdictinit causes refcount double-free, exploitable via heap spray to arbitrary memory write. Table of Contents 1. Background — netfilter / nftables overview 2. Root Cause...

ROS-20250130-02

Vulnerability of the nftverdictinit function in the net/netfilter/nftablesapi.c module of the operating system kernel Linux is related to the reuse of previously freed memory. Exploitation of the vulnerability could allow an attacker to affect the confidentiality, integrity, and availability of...

A use-after-free vulnerability exists in the Linux kernel's netfilter: nf_tables component

The Linux kernel is vulnerable to memory corruption due to improper error handling within the netfilter functionality. A local attacker could exploit this vulnerability in order to elevate their privileges. A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be...

kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function

A flaw was found in the Netfilter subsystem in the Linux kernel. This issue occurs in the nftverdictinit function, allowing positive values as a drop error within the hook verdict, therefore, the nfhookslow function can cause a double-free vulnerability when NFDROP is issued with a drop error tha...

kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function

A flaw was found in the Netfilter subsystem in the Linux kernel. This issue occurs in the nftverdictinit function, allowing positive values as a drop error within the hook verdict, therefore, the nfhookslow function can cause a double-free vulnerability when NFDROP is issued with a drop error tha...

Linux netfilter nft_verdict_init Heap Buffer Overflow

The vulnerability of the nftverdictinit function in the net/netfilter/nftablesapi.c module of the Linux operating system is related to the repeated use of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility...

CVE-2024-1086 Use-after-free in Linux kernel's netfilter: nf_tables component

A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation. The nftverdictinit function allows positive values as drop error within the hook verdict, and hence the nfhookslow function can cause a double free...

CVE-2024-1086: Use After Free

A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation. The nftverdictinit function allows positive values as drop error within the hook verdict, and hence the nfhookslow function can cause a double free...
