CVE-2026-68474

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An out-of-bounds access issue exists in the spufs mem mmap access() function. The function calculates the local store offset as address - vma->vm start but incorrectly validates this offset against vma->vm end instead of the local store size. On 64-bit systems, the offset typically remains below vma->vm end, preventing the clamp mechanism from triggering and allowing the len variable to remain unbounded relative to the LS SIZE buffer provided by ctx->ops->get ls().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
