Firstly, the ocfs2 super uses\n\"replay_map\" to trace online/offline slots, in order to recover offline\nslots during recovery and mount. But when ocfs2_truncate_log_init()\nreturns an error in ocfs2_mount_volume(), the memory of \"replay_map\" will\nnot be freed in error handling path. Secondly, the memory of \"replay_map\"\nwill not be freed if d_make_root() returns an error in ocfs2_fill_super().\nBut the memory of \"replay_map\" will be freed normally when completing\nrecovery and mount in ocfs2_complete_mount_recovery().\n\nFix the first problem by adding error handling path to free \"replay_map\"\nwhen ocfs2_truncate_log_init() fails. And fix the second problem by\ncalling ocfs2_free_replay_slots(osb) in the error handling path\n\"out_dismount\". In addition, since ocfs2_free_replay_slots() is static,\nit is necessary to remove its static attribute and declare it in header\nfile." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "fs/ocfs2/journal.c", "fs/ocfs2/journal.h", "fs/ocfs2/super.c" ], "versions": [ { "version": "9140db04ef185f934acf2b1b15b3dd5e6a6bfc22", "lessThan": "7ef516888c4d30ae41bfcd79e7077d86d92794c5", "status": "affected", "versionType": "git" }, { "version": "9140db04ef185f934acf2b1b15b3dd5e6a6bfc22", "lessThan": "2b7e59ed2e77136e9360274f8f0fc208a003e95c", "status": "affected", "versionType": "git" }, { "version": "9140db04ef185f934acf2b1b15b3dd5e6a6bfc22", "lessThan": "8059e200259e9c483d715fc2df6340c227c3e196", "status": "affected", "versionType": "git" }, { "version": "9140db04ef185f934acf2b1b15b3dd5e6a6bfc22", "lessThan": "4efe1d2db731bad19891e2fb9b338724b1f598cc", "status": "affected", "versionType": "git" }, { "version": "9140db04ef185f934acf2b1b15b3dd5e6a6bfc22", "lessThan": "50ab0ca3aff4da26037113d69f5a756d8c1a92cd", "status": "affected", "versionType": "git" }, { "version": "9140db04ef185f934acf2b1b15b3dd5e6a6bfc22", "lessThan": "ce2fcf1516d674a174d9b34d1e1024d64de9fba3", "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/ocfs2/journal.c", "fs/ocfs2/journal.h", "fs/ocfs2/super.c" ], "versions": [ { "version": "2.6.30", "status": "affected" }, { "version": "0", "lessThan": "2.6.30", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.229", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.163", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.107", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.0.16", "lessThanOrEqual": "6.0.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.2", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.2", "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": "2.6.30", "versionEndExcluding": "5.4.229" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.30", "versionEndExcluding": "5.10.163" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.30", "versionEndExcluding": "5.15.107" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.30", "versionEndExcluding": "6.0.16" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.30", "versionEndExcluding": "6.1.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.30", "versionEndExcluding": "6.2" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/7ef516888c4d30ae41bfcd79e7077d86d92794c5" }, { "url": "https://git.kernel.org/stable/c/2b7e59ed2e77136e9360274f8f0fc208a003e95c" }, { "url": "https://git.kernel.org/stable/c/8059e200259e9c483d715fc2df6340c227c3e196" }, { "url": "https://git.kernel.org/stable/c/4efe1d2db731bad19891e2fb9b338724b1f598cc" }, { "url": "https://git.kernel.org/stable/c/50ab0ca3aff4da26037113d69f5a756d8c1a92cd" }, { "url": "https://git.kernel.org/stable/c/ce2fcf1516d674a174d9b34d1e1024d64de9fba3" } ], "title": "ocfs2: fix memory leak in ocfs2_mount_volume()", "x_generator": { "engine": "bippy-1.2.0" } } } }
