{"id":"CVE-2026-90150","summary":"pnfs/blocklayout: Fix device leaks on parse failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npnfs/blocklayout: Fix device leaks on parse failure\n\nbl_parse_concat() and bl_parse_stripe() allocate a child device array and\nthen parse each child in turn.  If parsing a child fails, the failed child is\nnot counted in nr_children and the parent may be left with a children array\nthat bl_free_device() will not release when nr_children is zero.\n\nRelease the failed child and the already parsed children before returning the\nerror.  Also make bl_free_device() release the child array whenever the\nchildren pointer is set, so that partially initialised concat or stripe\ndevices are cleaned up correctly.\n\nbl_parse_scsi() can also fail after assigning d-\u003ebdev_file and dropping the\nfile reference.  Clear the pointer after fput() so that an outer cleanup path\ndoes not put it again.","modified":"2026-09-19T03:47:28.717259320Z","published":"2026-09-17T16:06:44.320Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90150.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1e1c36b206c659cf94c6755a1d821ed1babd32bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/23e4162405c456ce12c772d5882d306135e828ae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a2494964edac2a13e82441c2bf887548dc3be0b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c056f817e4200fb18079d5052c273a22f191ff0a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90150.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90150"},{"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":"5c83746a0cf2831d4b59f5cf99ef5fbf138564e4"},{"fixed":"8a2494964edac2a13e82441c2bf887548dc3be0b"},{"fixed":"1e1c36b206c659cf94c6755a1d821ed1babd32bc"},{"fixed":"23e4162405c456ce12c772d5882d306135e828ae"},{"fixed":"c056f817e4200fb18079d5052c273a22f191ff0a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90150.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.18.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90150.json"}}],"schema_version":"1.9.0"}
