Large input\nvalues can cause these calculations to wrap around before the resulting\ncoordinates are passed to SetOverlayViewPort().\n\nSetOverlayViewPort() packs the viewport coordinates into 16-bit\nregister fields. The X coordinates are additionally adjusted by +2\nand +1 before being written. Validate the coordinate calculations\nfor 32-bit wraparound and ensure that the adjusted coordinates fit\nwithin their 16-bit register fields before calling\nSetOverlayViewPort().\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/video/fbdev/kyro/fbdev.c"],"versions":[{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"d8c1a9579cbd8f4ac5cbd5a10f1afb5ee64adf30","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"2ac6e30a552e6f9932c21c865a5c69f40c8aef64","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"413d763439ba68e5d547538e6b6c7de97d5818a5","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"e8d4e4cf388daeb49704f3de10b203034f28eb90","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"a6decd4e72fc5846d3b268bd085a2089213fd5ee","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"33e54e3e0b2ca959304e62c3d84f0ad49bbe1afe","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"7bf36dc23bcf3496dec274a46ae0aaff4961ea03","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"7b5c7bc55e13e7f5ac7b1eaf5c6d690389ea5ee3","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/video/fbdev/kyro/fbdev.c"],"versions":[{"version":"2.6.12","status":"affected"},{"version":"0","lessThan":"2.6.12","status":"unaffected","versionType":"semver"},{"version":"5.10.270","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.221","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.188","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"5.10.270"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"5.15.221"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d8c1a9579cbd8f4ac5cbd5a10f1afb5ee64adf30"},{"url":"https://git.kernel.org/stable/c/2ac6e30a552e6f9932c21c865a5c69f40c8aef64"},{"url":"https://git.kernel.org/stable/c/413d763439ba68e5d547538e6b6c7de97d5818a5"},{"url":"https://git.kernel.org/stable/c/e8d4e4cf388daeb49704f3de10b203034f28eb90"},{"url":"https://git.kernel.org/stable/c/a6decd4e72fc5846d3b268bd085a2089213fd5ee"},{"url":"https://git.kernel.org/stable/c/33e54e3e0b2ca959304e62c3d84f0ad49bbe1afe"},{"url":"https://git.kernel.org/stable/c/7bf36dc23bcf3496dec274a46ae0aaff4961ea03"},{"url":"https://git.kernel.org/stable/c/7b5c7bc55e13e7f5ac7b1eaf5c6d690389ea5ee3"}],"title":"fbdev: kyro: Validate overlay viewport coordinates","x_generator":{"engine":"bippy-1.2.0"}}}}
