the Linux kernel, the following vulnerability has been resolved:\n\next4: fix infinite loop when replaying fast_commit\n\nWhen doing fast_commit replay an infinite loop may occur due to an\nuninitialized extent_status struct.  ext4_ext_determine_insert_hole() does\nnot detect the replay and calls ext4_es_find_extent_range(), which will\nreturn immediately without initializing the 'es' variable.\n\nBecause 'es' contains garbage, an integer overflow may happen causing an\ninfinite loop in this function, easily reproducible using fstest generic/039.\n\nThis commit fixes this issue by unconditionally initializing the structure\nin function ext4_es_find_extent_range().\n\nThanks to Zhang Yi, for figuring out the real problem!"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/ext4/extents_status.c"],"versions":[{"version":"8016e29f4362e285f0f7e38fadc61a5b7bdfdfa2","lessThan":"5ed0496e383cb6de120e56991385dce70bbb87c1","status":"affected","versionType":"git"},{"version":"8016e29f4362e285f0f7e38fadc61a5b7bdfdfa2","lessThan":"0619f7750f2b178a1309808832ab20d85e0ad121","status":"affected","versionType":"git"},{"version":"8016e29f4362e285f0f7e38fadc61a5b7bdfdfa2","lessThan":"181e63cd595c688194e07332f9944b3a63193de2","status":"affected","versionType":"git"},{"version":"8016e29f4362e285f0f7e38fadc61a5b7bdfdfa2","lessThan":"c6e67df64783e99a657ef2b8c834ba2bf54c539c","status":"affected","versionType":"git"},{"version":"8016e29f4362e285f0f7e38fadc61a5b7bdfdfa2","lessThan":"81f819c537d29932e4b9267f02411cbc8b355178","status":"affected","versionType":"git"},{"version":"8016e29f4362e285f0f7e38fadc61a5b7bdfdfa2","lessThan":"907c3fe532253a6ef4eb9c4d67efb71fab58c706","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/extents_status.c"],"versions":[{"version":"5.10","status":"affected"},{"version":"0","lessThan":"5.10","status":"unaffected","versionType":"semver"},{"version":"5.10.224","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.165","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.103","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.44","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.3","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":"5.10","versionEndExcluding":"5.10.224"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"5.15.165"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.1.103"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.6.44"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.10.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/5ed0496e383cb6de120e56991385dce70bbb87c1"},{"url":"https://git.kernel.org/stable/c/0619f7750f2b178a1309808832ab20d85e0ad121"},{"url":"https://git.kernel.org/stable/c/181e63cd595c688194e07332f9944b3a63193de2"},{"url":"https://git.kernel.org/stable/c/c6e67df64783e99a657ef2b8c834ba2bf54c539c"},{"url":"https://git.kernel.org/stable/c/81f819c537d29932e4b9267f02411cbc8b355178"},{"url":"https://git.kernel.org/stable/c/907c3fe532253a6ef4eb9c4d67efb71fab58c706"}],"title":"ext4:
