Summary
In the Linux kernel, the following vulnerability has been resolved: nilfs2: propagate directory read errors from nilfs_find_entry() Syzbot reported that a task hang occurs in vcs_open() during a fuzzing test for nilfs2. The root cause of this problem is that in nilfs_find_entry(), which searches for directory entries, ignores errors when loading a directory page/folio via nilfs_get_folio() fails. If the filesystem images is corrupted, and the i_size of the directory inode is large, and the directory page/folio is successfully read but fails the sanity check, for example when it is zero-filled, nilfs_check_folio() may continue to spit out error messages in bursts. Fix this issue by propagating the error to the callers when loading a page/folio fails in nilfs_find_entry(). The current interface of nilfs_find_entry() and its callers is outdated and cannot propagate error codes such as -EIO and -ENOMEM returned via nilfs_find_entry(), so fix it together.

La causa raíz de este problema es que en nilfs_find_entry(), que busca entradas de directorio, ignora los errores cuando falla la carga de una página/folio de directorio a través de nilfs_get_folio(). Si las imágenes del sistema de archivos están dañadas, y el i_size del inodo del directorio es grande, y la página/folio del directorio se lee correctamente pero falla la comprobación de cordura, por ejemplo, cuando está llena de ceros, nilfs_check_folio() puede seguir arrojando mensajes de error en ráfagas. Solucione este problema propagando el error a los llamadores cuando falla la carga de una página/folio en nilfs_find_entry(). La interfaz actual de nilfs_find_entry() y sus llamadores está desactualizada y no puede propagar códigos de error como -EIO y -ENOMEM devueltos a través de nilfs_find_entry(), así que arréglenlo juntos.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-755\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"2.6.30\",\"versionEndExcluding\":\"4.19.323\",\"matchCriteriaId\":\"68A7ECD8-BE83-4540-8A15-A841E57A82E8\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.20\",\"versionEndExcluding\":\"5.4.285\",\"matchCriteriaId\":\"B5A89369-320F-47FC-8695-56F61F87E4C0\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.5\",\"versionEndExcluding\":\"5.10.228\",\"matchCriteriaId\":\"9062315F-AB89-4ABE-8C13-B75927689F66\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.11\",\"versionEndExcluding\":\"5.15.169\",\"matchCriteriaId\":\"18BEDAD6-86F8-457C-952F-C35698B3D07F\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"6.1.114\",\"matchCriteriaId\":\"10FD2B3E-C7D9-4A9C-BD64-41877EDF88EB\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.2\",\"versionEndExcluding\":\"6.6.58\",\"matchCriteriaId\":\"6B9489BC-825E-4EEE-8D93-F93C801988C8\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.7\",\"versionEndExcluding\":\"6.11.5\",\"matchCriteriaId\":\"6E62D61A-F704-44DB-A311-17B7534DA7BC\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc1:*:*:*:*:*:*\",\"matchCriteriaId\":\"7F361E1D-580F-4A2D-A509-7615F73167A1\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc2:*:*:*:*:*:*\",\"matchCriteriaId\":\"925478D0-3E3D-4E6F-ACD5-09F28D5DF82C\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.12:rc3:*:*:*:*:*:*\",\"matchCriteriaId\":\"3C95E234-D335-4B6C-96BF-E2CEBD8654ED\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/08cfa12adf888db98879dbd735bc741360a34168\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/270a6f9df35fa2aea01ec23770dc9b3fc9a12989\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/9698088ac7704e260f492d9c254e29ed7dd8729a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/b4b3dc9e7e604be98a222e9f941f5e93798ca475\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/bb857ae1efd3138c653239ed1e7aef14e1242c81\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/c1d0476885d708a932980b0f28cd90d9bd71db39\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/edf8146057264191d5bfe5b91773f13d936dadd3\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/efa810b15a25531cbc2f527330947b9fe16916e7\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}",
