{"apiVersion":"1.0","identifier":"CVE-2026-80610","description":"In the Linux kernel, the following vulnerability has been resolved: net: enetc: fix potential divide-by-zero when num_vsi is zero For i.MX94 series, all the standalone ENETCs do not support SR-IOV, so pf->caps.num_vsi is zero. This leads to a divide-by-zero in enetc4_default_rings_allocation() when distributing rings among PF and VFs. Division by zero is undefined behavior in C. On ARM64, the UDIV/SDIV instructions silently return zero rather than raising an exception, so the issue does not cause a visible crash. However, relying on this behavior is incorrect and poses a cross-platform compatibility risk. Add an explicit check for num_vsi == 0 and return early after the PF-s rings have been configured.","publishedAt":"2026-08-28T08:16:44","lastModifiedAt":"2026-08-28T08:16:44","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-80610","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00155,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-80610","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-80610","en":"https://www.redsauce.net/en/cves/CVE-2026-80610","fr":"https://www.redsauce.net/fr/cves/CVE-2026-80610","pt":"https://www.redsauce.net/pt/cves/CVE-2026-80610","de":"https://www.redsauce.net/de/cves/CVE-2026-80610","sk":"https://www.redsauce.net/sk/cves/CVE-2026-80610","el":"https://www.redsauce.net/el/cves/CVE-2026-80610"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-80610"}}
