{"apiVersion":"1.0","identifier":"CVE-2026-74741","description":"In the Linux kernel, the following vulnerability has been resolved: net: ngbe: fix NULL pointer dereference in non-MSI-X interrupt enabling In non-MSI-X mode (such as legacy INTx or single MSI), wx->msix_entry is not allocated or initialized. Calling NGBE_INTR_MISC(wx) dereferences wx->msix_entry->entry, leading to a NULL pointer dereference crash. This issue was introduced by fixing the IRQ vector when the number of VFs is 7. Fix the issue by explicitly checking `pdev->msix_enabled` to determine the correct vector index. Additionally, as a side fix, set the interrupt mask to BIT(0) for the non-MSI-X fallback. In MSI/INTx mode, the MISC and queue interrupts share vector 0, and the WX_PX_MISC_IVAR register is only valid in the MSI-X case. Thus, BIT(0) is the correct mask for the miscellaneous cause when MSI-X is disabled.","publishedAt":"2026-08-26T15:16:52","lastModifiedAt":"2026-08-27T06:17:23","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74741","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00451,"riskScore":0.78,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74741","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74741","en":"https://www.redsauce.net/en/cves/CVE-2026-74741","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74741","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74741","de":"https://www.redsauce.net/de/cves/CVE-2026-74741","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74741","el":"https://www.redsauce.net/el/cves/CVE-2026-74741"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74741"}}
