HighCVSS 7.8Exploitation Probability (EPSS)
Elevated risk57th percentile - higher than 57% of all known CVEs
Summary
A use-after-free flaw was found in the Linux kernel's netfilter related to triggering the nft_pipapo_remove function without the NFT_SET_EXT_KEY_END element. This could lead to system crashes or privilege escalation by a local user.
Risk Assessment
This vulnerability poses a risk to system stability and security, allowing local users to potentially gain elevated privileges.
Recommendation
It is recommended to update the Linux kernel to the latest version to mitigate this vulnerability and to monitor the system for unauthorized activities.
Other vulnerabilities in Linux kernel netfilter
See all- CVE-2024-27065High
A vulnerability in the Linux kernel has been resolved in netfilter, which involved improper comparison of internal table flags during updates. This issue has been fixed by restoring the skipping of transactions if the table update does not modify flags.
- CVE-2026-45860High
A vulnerability in the Linux kernel's netfilter module has been resolved regarding the connection clean-up limit. Fixes have been implemented to increase the clean-up limit to 64 connections and optimize the process of collecting unused connections.
- CVE-2026-43116High
A vulnerability has been identified in the Linux kernel within the netfilter module regarding safe access to the master conntrack object. The issue arises because this object can disappear, leading to invalid access.
- CVE-2024-27397High
A vulnerability has been identified in the Linux kernel's netfilter module regarding the use of a timestamp to check for set element expiration. A timestamp field has been added at the beginning of the transaction to avoid an element expiring while the control plane transaction is still ongoing.
- CVE-2023-4147High
A use-after-free flaw was found in the Linux kernel’s Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
Original NVD description (English source)
A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.
