CVE-2024-26581 is a vulnerability in the Linux kernel related to the netfilter component and its rbtree implementation. Specifically, the issue involves the nft_set_rbtree function and its lazy garbage collection process potentially collecting an end interval element prematurely. With an SVRS of 73, this vulnerability is considered high risk. While the CVSS score is 7.8 indicating a medium severity, the SVRS highlights an elevated urgency because active exploits exist. This could lead to unexpected behavior or system instability. The fact that exploits are actively available and it is tagged "In The Wild", this makes patching CVE-2024-26581 a priority to mitigate potential security risks and maintain system stability. Immediate patching is recommended to protect systems from potential exploitation.
