netfilter: nft_set_pipapo: clamp maximum map bucket size to INT_MAX
Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 0ab3de047808f375a36cd345225572eb3366f3c6, 1fe27f97944017a9d3c5af4d6d95282bff0f1147, 4abccfb61f422300be014b8e734c63344306f009; cbl2 kernel 5.15.202.1-1 on CBL-Mariner 2.0 Release Notes.
Low priority for now. Upgrade to Linux Linux 0ab3de047808f375a36cd345225572eb3366f3c6, 1fe27f97944017a9d3c5af4d6d95282bff0f1147, 4abccfb61f422300be014b8e734c63344306f009; cbl2 kernel 5.15.202.1-1 on CBL-Mariner 2.0 Release Notes or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_set_pipapo: clamp maximum map bucket size to INT_MAX Otherwise, it is possible to hit WARN_ON_ONCE in __kvmalloc_node_noprof() when resizing hashtable because __GFP_NOWARN is unset. Similar to: b541ba7d1f5a ("netfilter: conntrack: clamp maximum hashtable size to INT_MAX")
