The reason\nis that while all other threads will exit, the mounting thread (or process)\nwill keep the device fd open, which will prevent an abort from happening.\n\nThis is a regression from the async mount case, where the mount was done\nfirst, and the FUSE_INIT processing afterwards, in which case there's no\nsuch recursive syscall keeping the fd open."}],"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","fs/fuse/fuse_i.h","fs/fuse/inode.c"],"versions":[{"version":"dfb84c33079497bf27058b15780e1c7bba4c371b","lessThan":"0c7fca880a40a209a9c92be14143996d14b93ff6","status":"affected","versionType":"git"},{"version":"dfb84c33079497bf27058b15780e1c7bba4c371b","lessThan":"300e812b882a174dca675d8028684001ad5826bc","status":"affected","versionType":"git"},{"version":"dfb84c33079497bf27058b15780e1c7bba4c371b","lessThan":"204aa22a686bfee48daca7db620c1e017615f2ff","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","fs/fuse/fuse_i.h","fs/fuse/inode.c"],"versions":[{"version":"6.18","status":"affected"},{"version":"0","lessThan":"6.18","status":"unaffected","versionType":"semver"},{"version":"6.18.25","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.2","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1-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":"6.18","versionEndExcluding":"6.18.25"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.0.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.1-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0c7fca880a40a209a9c92be14143996d14b93ff6"},{"url":"https://git.kernel.org/stable/c/300e812b882a174dca675d8028684001ad5826bc"},{"url":"https://git.kernel.org/stable/c/204aa22a686bfee48daca7db620c1e017615f2ff"}],"title":"fuse: abort on fatal signal during sync init","x_generator":{"engine":"bippy-1.2.0"}}}}
