Description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper input validation in the netfilter nft_set_rbtree component when handling interval overlap in set elements. A local user can send a specially crafted request to cause a denial of service.
Exploitation requires the ability to insert or delete interval elements in nftables sets. The issue specifically affects open intervals at the end of a set, where missing end-element validation can lead to inconsistent state and rejection of valid operations.
Remediation
Install security update from vendor's repository.
