In this scenario, the next\ncall to ext4_write_begin() will not prepare the inline data xattr for\nwriting, but ext4_journalled_write_end() will incorrectly attempt to write\nto it, triggering a BUG_ON(pos + len > EXT4_I(inode)->i_inline_size) in\next4_write_inline_data() since i_inline_size was not expanded.\n\nFix this by ensuring that ext4_journalled_write_end() only calls\next4_write_inline_data_end() if the EXT4_STATE_MAY_INLINE_DATA flag is\nset, mirroring the behavior of ext4_write_end() and ext4_da_write_end()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/ext4/inode.c"],"versions":[{"version":"3fdcfb668fd78ec92d9bc2daddf1d41e2a8a30bb","lessThan":"260830a9a706f5d335398236fc788ce32f220de1","status":"affected","versionType":"git"},{"version":"3fdcfb668fd78ec92d9bc2daddf1d41e2a8a30bb","lessThan":"9808ae9fae996afa942bd963a39c9b1cdeebd0bd","status":"affected","versionType":"git"},{"version":"3fdcfb668fd78ec92d9bc2daddf1d41e2a8a30bb","lessThan":"f00f5c0dd55319bc33b76f72c853bda0e0a32eda","status":"affected","versionType":"git"},{"version":"3fdcfb668fd78ec92d9bc2daddf1d41e2a8a30bb","lessThan":"0ae42b51607240990614e0843f0d3529aaff62cc","status":"affected","versionType":"git"},{"version":"3fdcfb668fd78ec92d9bc2daddf1d41e2a8a30bb","lessThan":"ad09aa45965d3fafaf9963bc78109b73c0f9ac8d","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/ext4/inode.c"],"versions":[{"version":"3.8","status":"affected"},{"version":"0","lessThan":"3.8","status":"unaffected","versionType":"semver"},{"version":"6.6.145","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.97","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.40","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"3.8","versionEndExcluding":"6.6.145"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8","versionEndExcluding":"6.12.97"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.8","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/260830a9a706f5d335398236fc788ce32f220de1"},{"url":"https://git.kernel.org/stable/c/9808ae9fae996afa942bd963a39c9b1cdeebd0bd"},{"url":"https://git.kernel.org/stable/c/f00f5c0dd55319bc33b76f72c853bda0e0a32eda"},{"url":"https://git.kernel.org/stable/c/0ae42b51607240990614e0843f0d3529aaff62cc"},{"url":"https://git.kernel.org/stable/c/ad09aa45965d3fafaf9963bc78109b73c0f9ac8d"}],"title":"ext4: fix kernel BUG in ext4_write_inline_data_end","x_generator":{"engine":"bippy-1.2.0"}}}}
