{"apiVersion":"1.0","identifier":"CVE-2026-72278","description":"In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Re-translate VNCR before injecting abort KVM faults in the VNCR page with FOLL_WRITE whenever the guest aborts for a write, similar to how a regular stage-2 mapping is handled. It is entirely possible that the guest reads from the VNCR before writing to it, in which case the PFN could only be read-only. Invalidate the VNCR TLB and re-fetch the translation upon taking a VNCR abort, allowing the host mapping to be faulted in for write the second time around. Interestingly enough, this also satisfies the ordering requirements of FEAT_ETS2/3 between descriptor updates and MMU faults.","publishedAt":"2026-08-15T06:21:57","lastModifiedAt":"2026-08-17T06:18:30","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72278","cvssScore":9.3,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00191,"riskScore":0.95,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72278","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72278","en":"https://www.redsauce.net/en/cves/CVE-2026-72278","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72278","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72278","de":"https://www.redsauce.net/de/cves/CVE-2026-72278","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72278","el":"https://www.redsauce.net/el/cves/CVE-2026-72278"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72278"}}
