An ext4_emergency_state() check is also added to avoid attempting\nto abort the journal in an emergency state.\n\nAdditionally, ext4_put_io_end_defer() is refactored to call\next4_io_end_defer_completion() directly instead of being open-coded.\nThis also prevents starting an unnecessary worker when EXT4_IO_END_FAILED\nis set but data_err=abort is not enabled.\n\nThis ensures that the check in ext4_put_io_end_defer() is consistent with\nthe check in ext4_end_bio(). Otherwise, we might add an io_end to the\ni_rsv_conversion_list and then call ext4_finish_bio(), after which the\ninode could be freed before ext4_end_io_rsv_work() is called, triggering\na use-after-free issue."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/ext4/page-io.c"],"versions":[{"version":"ce51afb8cc5e1867ea0dfdf5e92ddbe31a1fad5d","lessThan":"ac999862b98a0f49e858e509f776be51406f1e77","status":"affected","versionType":"git"},{"version":"ce51afb8cc5e1867ea0dfdf5e92ddbe31a1fad5d","lessThan":"469c44e66e2110054949609dde095788320139d0","status":"affected","versionType":"git"},{"version":"ce51afb8cc5e1867ea0dfdf5e92ddbe31a1fad5d","lessThan":"c678bdc998754589cea2e6afab9401d7d8312ac4","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/page-io.c"],"versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"6.15.10","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16.1","lessThanOrEqual":"6.16.*","status":"unaffected","versionType":"semver"},{"version":"6.17","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":"6.15","versionEndExcluding":"6.15.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"6.16.1"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"6.17"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ac999862b98a0f49e858e509f776be51406f1e77"},{"url":"https://git.kernel.org/stable/c/469c44e66e2110054949609dde095788320139d0"},{"url":"https://git.kernel.org/stable/c/c678bdc998754589cea2e6afab9401d7d8312ac4"}],"title":"ext4: fix inode use after free in ext4_end_io_rsv_work()","x_generator":{"engine":"bippy-1.2.0"}}}}
