{"apiVersion":"1.0","identifier":"CVE-2026-68474","description":"In the Linux kernel, the following vulnerability has been resolved: powerpc/spufs: fix out-of-bounds access in spufs_mem_mmap_access() spufs_mem_mmap_access() computes the local store offset as address - vma->vm_start, but bounds-checks it against vma->vm_end instead of the local store size. On 64-bit, offset is always well below vma->vm_end, so the clamp never fires and len stays unbounded against the LS_SIZE buffer returned by ctx->ops->get_ls(). Reject offsets at or beyond LS_SIZE and clamp len to the remaining space, mirroring the guard already used by spufs_mem_mmap_fault() and spufs_ps_fault().","publishedAt":"2026-08-15T06:20:34","lastModifiedAt":"2026-08-17T06:17:56","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-68474","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00164,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-68474","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-68474","en":"https://www.redsauce.net/en/cves/CVE-2026-68474","fr":"https://www.redsauce.net/fr/cves/CVE-2026-68474","pt":"https://www.redsauce.net/pt/cves/CVE-2026-68474","de":"https://www.redsauce.net/de/cves/CVE-2026-68474","sk":"https://www.redsauce.net/sk/cves/CVE-2026-68474","el":"https://www.redsauce.net/el/cves/CVE-2026-68474"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-68474"}}
