{"apiVersion":"1.0","identifier":"CVE-2026-74277","description":"In the Linux kernel, the following vulnerability has been resolved: iommu/dma-iommu: Fix wrong scatterlist length assignment in P2PDMA path In iommu_dma_map_sg(), when handling PCI P2PDMA cases, the DMA length of the current scatterlist segment `s` is incorrectly assigned from the head entry `sg->length` instead of the current entry `s->length`. This typo causes all P2PDMA segments in the scatterlist to inherit the length of the first segment, leading to corrupted DMA lengths for multi- segment scatterlists. Fix this by using `s->length` instead of `sg->length`.","publishedAt":"2026-08-15T06:22:27","lastModifiedAt":"2026-08-17T06:19:21","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74277","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00154,"riskScore":0.89,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74277","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74277","en":"https://www.redsauce.net/en/cves/CVE-2026-74277","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74277","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74277","de":"https://www.redsauce.net/de/cves/CVE-2026-74277","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74277","el":"https://www.redsauce.net/el/cves/CVE-2026-74277"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74277"}}
