the attacker directly issues the sysfs read that invokes the vulnerable measurement path.\nS:U - Impact is confined to kernel driver behavior on the local system; there is no crossing of security boundaries such as VM escape, sandbox escape, or IOMMU bypass.\nC:H - The bug is an out-of-bounds read of kernel memory (up to 12 bytes past a static array in .rodata) when the integration-time index is 5, 6, or 7; per kernel scoring guidance, out-of-bounds reads are rated High unless strictly bounded, and the leaked value is not returned to userspace.\nI:N - The flaw is a read-only out-of-bounds array access; the out-of-bounds value is consumed only by msleep() and does not modify memory or enable arbitrary writes or code execution.\nA:H - An out-of-bounds integration-time value fed into msleep() can produce a very long uninterruptible sleep while the driver mutex is held, blocking all concurrent sensor reads and causing a denial of service on embedded/IoT systems that depend on the UV sensor."}]}],"providerMetadata":{"shortName":"Linux","orgId":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","dateUpdated":"2026-08-17T04:50:38.188Z"},"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.8","versionEndExcluding":"6.12.95"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.8","versionEndExcluding":"6.18.37"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.8","versionEndExcluding":"7.0.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.8","versionEndExcluding":"7.1.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.8","versionEndExcluding":"7.2"}]}]}],"x_generator":{"engine":"bippy-1.2.0"}}}}}
