Title
ext4: add EXT4_IGET_BAD flag to prevent unexpected bad inode
Summary
In the Linux kernel, the following vulnerability has been resolved: ext4: add EXT4_IGET_BAD flag to prevent unexpected bad inode There are many places that will get unhappy (and crash) when ext4_iget() returns a bad inode. However, if iget the boot loader inode, allows a bad inode to be returned, because the inode may not be initialized. This mechanism can be used to bypass some checks and cause panic. To solve this problem, we add a special iget flag EXT4_IGET_BAD. Only with this flag we'd be returning bad inode from ext4_iget(), otherwise we always return the error code if the inode is bad inode.(suggested by Jan Kara)

To solve this\\nproblem, we add a special iget flag EXT4_IGET_BAD. Only with this flag\\nwe\u0027d be returning bad inode from ext4_iget(), otherwise we always return\\nthe error code if the inode is bad inode.(suggested by Jan Kara)\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"fs/ext4/ext4.h\",\"fs/ext4/inode.c\",\"fs/ext4/ioctl.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"393d1d1d76933886d5e1ce603214c9987589c6d5\",\"lessThan\":\"2142dfa1de61e25b83198af0308ec7689cca25d3\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"393d1d1d76933886d5e1ce603214c9987589c6d5\",\"lessThan\":\"c0a738875c2e9c8c3366d792f8bf7fe508d5e5a5\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"393d1d1d76933886d5e1ce603214c9987589c6d5\",\"lessThan\":\"f7e6b5548f915d7aa435d0764d41eacfb49c6e09\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"393d1d1d76933886d5e1ce603214c9987589c6d5\",\"lessThan\":\"f725b290ed79ad61e4f721fee95a287892d8b1ad\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"393d1d1d76933886d5e1ce603214c9987589c6d5\",\"lessThan\":\"488a5c2bf7543c3cd3f07a025f2e62be91599430\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"393d1d1d76933886d5e1ce603214c9987589c6d5\",\"lessThan\":\"63b1e9bccb71fe7d7e3ddc9877dbdc85e5d2d023\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"fs/ext4/ext4.h\",\"fs/ext4/inode.c\",\"fs/ext4/ioctl.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"3.10\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"3.10\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.4.229\",\"lessThanOrEqual\":\"5.4.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.10.163\",\"lessThanOrEqual\":\"5.10.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.15.87\",\"lessThanOrEqual\":\"5.15.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.0.18\",\"lessThanOrEqual\":\"6.0.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.1.4\",\"lessThanOrEqual\":\"6.1.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.2\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"NVD-CWE-noinfo\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"3.10\",\"versionEndExcluding\":\"5.4.229\",\"matchCriteriaId\":\"D7CA85C8-20BC-4F07-8FD9-16F788191F2C\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.5\",\"versionEndExcluding\":\"5.10.163\",\"matchCriteriaId\":\"D05D31FC-BD74-4F9E-B1D8-9CED62BE6F65\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.11\",\"versionEndExcluding\":\"5.15.87\",\"matchCriteriaId\":\"7B9E5B1C-CD46-4790-9500-615863850401\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"6.0.18\",\"matchCriteriaId\":\"08D38C5F-9644-4549-BBA6-F0860F024D14\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.1\",\"versionEndExcluding\":\"6.1.4\",\"matchCriteriaId\":\"BC4189D9-5478-4E88-A78D-9C1DE29B217C\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/2142dfa1de61e25b83198af0308ec7689cca25d3\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/488a5c2bf7543c3cd3f07a025f2e62be91599430\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/63b1e9bccb71fe7d7e3ddc9877dbdc85e5d2d023\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/c0a738875c2e9c8c3366d792f8bf7fe508d5e5a5\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/f725b290ed79ad61e4f721fee95a287892d8b1ad\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"t
