{"apiVersion":"1.0","identifier":"CVE-2026-72312","description":"In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: fix VF bringup affecting PF promiscuous state Mbox handling of nix_set_rx_mode for a VF with promiscuous and all_multi flags set to false causes deletion of the PF-s promiscuous and allmulti MCAM rules. This occurs because the APIs that enable/disable these rules operate only on the PF, even when the mbox request is made via a VF interface. Guard both rvu_npc_enable_allmulti_entry() and rvu_npc_enable_promisc_entry() disable paths with an is_vf() check so that a VF bringing up or tearing down its interface cannot inadvertently clear the PF-s MCAM rules.","publishedAt":"2026-08-15T06:22:04","lastModifiedAt":"2026-08-17T06:18:34","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72312","cvssScore":7.9,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:H","epssProbability":0.00154,"riskScore":0.8,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72312","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72312","en":"https://www.redsauce.net/en/cves/CVE-2026-72312","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72312","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72312","de":"https://www.redsauce.net/de/cves/CVE-2026-72312","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72312","el":"https://www.redsauce.net/el/cves/CVE-2026-72312"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72312"}}
