the Linux kernel, the following vulnerability has been resolved:\n\nfuse: Initialize beyond-EOF page contents before setting uptodate\n\nfuse_notify_store(), unlike fuse_do_readpage(), does not enable page\nzeroing (because it can be used to change partial page contents).\n\nSo fuse_notify_store() must be more careful to fully initialize page\ncontents (including parts of the page that are beyond end-of-file)\nbefore marking the page uptodate.\n\nThe current code can leave beyond-EOF page contents uninitialized, which\nmakes these uninitialized page contents visible to userspace via mmap().\n\nThis is an information leak, but only affects systems which do not\nenable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the\ncorresponding kernel command line parameter)."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/fuse/dev.c"],"versions":[{"version":"a1d75f258230b75d46aecdf28b2e732413028863","lessThan":"49934861514d36d0995be8e81bb3312a499d8d9a","status":"affected","versionType":"git"},{"version":"a1d75f258230b75d46aecdf28b2e732413028863","lessThan":"33168db352c7b56ae18aa55c2cae1a1c5905d30e","status":"affected","versionType":"git"},{"version":"a1d75f258230b75d46aecdf28b2e732413028863","lessThan":"4690e2171f651e2b415e3941ce17f2f7b813aff6","status":"affected","versionType":"git"},{"version":"a1d75f258230b75d46aecdf28b2e732413028863","lessThan":"8c78303eafbf85a728dd84d1750e89240c677dd9","status":"affected","versionType":"git"},{"version":"a1d75f258230b75d46aecdf28b2e732413028863","lessThan":"831433527773e665bdb635ab5783d0b95d1246f4","status":"affected","versionType":"git"},{"version":"a1d75f258230b75d46aecdf28b2e732413028863","lessThan":"ac42e0f0eb66af966015ee33fd355bc6f5d80cd6","status":"affected","versionType":"git"},{"version":"a1d75f258230b75d46aecdf28b2e732413028863","lessThan":"18a067240817bee8a9360539af5d79a4bf5398a5","status":"affected","versionType":"git"},{"version":"a1d75f258230b75d46aecdf28b2e732413028863","lessThan":"3c0da3d163eb32f1f91891efaade027fa9b245b9","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/fuse/dev.c"],"versions":[{"version":"2.6.36","status":"affected"},{"version":"0","lessThan":"2.6.36","status":"unaffected","versionType":"semver"},{"version":"4.19.321","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.283","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.225","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.166","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.107","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.48","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.7","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11","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":"2.6.36","versionEndExcluding":"4.19.321"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.4.283"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.10.225"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"5.15.166"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.1.107"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.6.48"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.10.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.36","versionEndExcluding":"6.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/49934861514d36d0995be8e81bb3312a499d8d9a"},{"url":"https://git.kernel.org/stable/c/33168db352c7b56ae18aa55c2cae1a1c5905d30e"},{"url":"https://git.kernel.org/stable/c/4690e2171f651e2b415e3941ce17f2f7b813aff6"},{"url":"https://git.kernel.org/stable/c/8c78303eafbf85a728dd84d1750e89240c677dd9"},{"url":"https://git.kernel.org/stable/c/831433527773e665bdb635ab5783d0b95d1246f4"},{"url":"https://git.kernel.org/stable/c/ac42e0f0eb66af966015ee33fd355bc6f5d80cd6"},{"url":"https://git.kernel.org/stable/c/18a067240817bee8a9360539af5d79a4bf5398a5"},{"url":"https://git.kernel.org/stable/c/3c0da3d163eb32f1f91891efaade027fa9b245b9"},{"url":"https://project-zero.issues.chromium.org/issues/42451729"}],"title":"fuse:
