PoC released for Critical Privilege Escalation Vulnerability in Linux Kernel
Date: June 5, 2024
CVE: CVE-2023-3390
Vulnerability Type: Use-After-Free
CWE: [[CWE-416]]
Sources: SSD-disclosure NVD, Debian Security Tracker, SnykSynopsis
A PoC Exploit has been released for Linux Kernel use-after-free vulnerability, identified as CVE-2023-3390, has been discovered in the Linux kernel's netfilter subsystem. This flaw, present in the
nf_tables_api.cfile, can allow a local attacker with the ability to execute low-privileged code on the target system to escalate privileges due to mishandled error handling. The vulnerability has been patched.Issue Summary
CVE-2023-3390 is a critical vulnerability found in the Linux kernel's netfilter subsystem. The issue arises from a use-after-free error in the
NFT_MSG_NEWRULEhandling, potentially allowing attackers to exploit a dangling pointer within the same transaction. This flaw enables local attackers to gain elevated privileges on affected systems.Technical Key Findings
The root cause of CVE-2023-3390, a critical privilege escalation vulnerability in the Linux kernel, lies in the improper management of integer values within the
nft_parse_register_storefunction of the Netfilter subsystem. Specifically, this vulnerability is due to an integer overflow issue within thenft_validate_register_storefunction, which fails to correctly handle certain large values for register indices.The CVE-2023-3390 vulnerability arises from an integer overflow in the validation logic of the Netfilter subsystem, which fails to properly handle large register values, allowing an attacker to perform out-of-bounds writes to kernel memory. This leads to potential privilege escalation, compromising the affected system. It is crucial to apply patches that correct this validation flaw to mitigate the risk.
For details, see the detailed root cause analysis at SSD Secure Disclosure
Vulnerable Products
The vulnerability affects Debian 11 (Linux Kernel 5.10)
Impact Assessment
Exploiting this vulnerability allows a local attacker to gain root access, which can lead to severe consequences such as system compromise, data breaches, and service disruptions.
Patches or Workaround
Patches for CVE-2023-3390 have been released. Administrators are advised to update their Linux kernel to versions that include the commit
1240eb93f0616b21c675416516ff3d74798fdc97. an updated kernel in July 2023: https://tracker.debian.org/news/1449040/accepted-linux-510179-3-source-into-oldstable-securityTags
