Fill_meta_index() is called to allocate (via empty_meta_index())\n and fill a metadata index. It however suffers a data read error\n and aborts, invalidating the newly returned empty metadata index.\n It does this by setting the inode number of the index to zero,\n which means unused (zero is not a valid inode number).\n\n2. When fill_meta_index() is subsequently called again on another\n read operation, locate_meta_index() returns the previous index\n because it matches the inode number of 0. Because this index\n has been returned it is expected to have been filled, and because\n it hasn't been, an out of bounds access is performed.\n\nThis patch adds a sanity check which checks that the inode number\nis not zero when the inode is created and returns -EINVAL if it is.\n\n[phillip@squashfs.org.uk: whitespace fix]","state":0,"publishedAt":"2024-05-01T05:27:11.032+00:00","modifiedAt":"2026-10-15T00:39:42.202+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"fs/squashfs/inode.c\"\n ],\n \"versions\": [\n {\n \"version\": \"6545b246a2c815a8fcd07d58240effb6ec3481b1\",\n \"lessThan\": \"32c114a58236fe67141634774559f21f1dc96fd7\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6545b246a2c815a8fcd07d58240effb6ec3481b1\",\n \"lessThan\": \"4a1b6f89825e267e156ccaeba3d235edcac77f94\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6545b246a2c815a8fcd07d58240effb6ec3481b1\",\n \"lessThan\": \"cf46f88b92cfc0e32bd8a21ba1273cff13b8745f\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6545b246a2c815a8fcd07d58240effb6ec3481b1\",\n \"lessThan\": \"5b99dea79650b50909c50aba24fbae00f203f013\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6545b246a2c815a8fcd07d58240effb6ec3481b1\",\n \"lessThan\": \"be383effaee3d89034f0828038f95065b518772e\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6545b246a2c815a8fcd07d58240effb6ec3481b1\",\n \"lessThan\": \"7def00ebc9f2d6a581ddf46ce4541f84a10680e5\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6545b246a2c815a8fcd07d58240effb6ec3481b1\",\n \"lessThan\": \"9253c54e01b6505d348afbc02abaa4d9f8a01395\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"fs/squashfs/inode.c\"\n ],\n \"versions\": [\n {\n \"version\": \"2.6.29\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"2.6.29\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.4.291\",\n \"lessThanOrEqual\": \"5.4.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.235\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.179\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.130\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.30\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.8.8\",\n \"lessThanOrEqual\": \"6.8.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.9\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/32c114a58236fe67141634774559f21f1dc96fd7","https://git.kernel.org/stable/c/4a1b6f89825e267e156ccaeba3d235edcac77f94","https://git.kernel.org/stable/c/cf46f88b92cfc0e32bd8a21ba1273cff13b8745f","https://git.kernel.org/stable/c/5b99dea79650b50909c50aba24fbae00f203f013","https://git.kernel.org/stable/c/be383effaee3d89034f0828038f95065b518772e","https://git.kernel.org/stable/c/7def00ebc9f2d6a581ddf46ce4541f84a10680e5","https://git.kernel.org/stable/c/9253c54e01b6505d348afbc02abaa4d9f8a01395"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-26982","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-26982","identifiers":["CVE-2024-26982"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
