{"id":"CVE-2024-47723","summary":"jfs: fix out-of-bounds in dbNextAG() and diAlloc()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\njfs: fix out-of-bounds in dbNextAG() and diAlloc()\n\nIn dbNextAG() , there is no check for the case where bmp-\u003edb_numag is\ngreater or same than MAXAG due to a polluted image, which causes an\nout-of-bounds. Therefore, a bounds check should be added in dbMount().\n\nAnd in dbNextAG(), a check for the case where agpref is greater than\nbmp-\u003edb_numag should be added, so an out-of-bounds exception should be\nprevented.\n\nAdditionally, a check for the case where agno is greater or same than\nMAXAG should be added in diAlloc() to prevent out-of-bounds.","modified":"2026-04-16T04:36:02.593174736Z","published":"2024-10-21T12:13:57.614Z","related":["SUSE-SU-2024:3984-1","SUSE-SU-2024:3986-1","SUSE-SU-2024:4315-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4364-1","SUSE-SU-2024:4376-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/47xxx/CVE-2024-47723.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0338e66cba272351ca9d7d03f3628e390e70963b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/128d5cfdcf844cb690c9295a3a1c1114c21fc15a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ad6284c8d433f8a213111c5c44ead4d9705b622"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6ce8b6ab44a8b5918c0ee373d4ad19d19017931b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/96855f40e152989c9e7c20c4691ace5581098acc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c1ba4b8ca799ff1d99d01f37d7ccb7d5ba5533d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d1017d2a0f3f16dc1db5120e7ddbe7c6680425b0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e63866a475562810500ea7f784099bfe341e761a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ead82533278502428883085a787d5a00f15e5eb9"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/47xxx/CVE-2024-47723.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-47723"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2"},{"fixed":"d1017d2a0f3f16dc1db5120e7ddbe7c6680425b0"},{"fixed":"5ad6284c8d433f8a213111c5c44ead4d9705b622"},{"fixed":"0338e66cba272351ca9d7d03f3628e390e70963b"},{"fixed":"ead82533278502428883085a787d5a00f15e5eb9"},{"fixed":"6ce8b6ab44a8b5918c0ee373d4ad19d19017931b"},{"fixed":"c1ba4b8ca799ff1d99d01f37d7ccb7d5ba5533d2"},{"fixed":"128d5cfdcf844cb690c9295a3a1c1114c21fc15a"},{"fixed":"96855f40e152989c9e7c20c4691ace5581098acc"},{"fixed":"e63866a475562810500ea7f784099bfe341e761a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-47723.json"}}],"schema_version":"1.7.5"}
