{"id":"CVE-2026-72033","summary":"orangefs: keep the readdir entry size 64-bit in fill_from_part()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\norangefs: keep the readdir entry size 64-bit in fill_from_part()\n\nfill_from_part() computes the size of a directory entry in size_t but\nstores it in a __u32. An entry length near U32_MAX wraps it to a small\nvalue, bypasses the bounds check, and is then used to index the entry,\nreading far past the directory part -- an out-of-bounds read that oopses\nthe kernel.\n\nCompute the size as a u64 so it cannot truncate; the bounds check then\nrejects the entry. The trailer is supplied by the userspace client.","modified":"2026-08-18T03:56:36.216053362Z","published":"2026-08-15T05:51:55.102Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72033.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/07c05601a9a8e5d4481b2a4a16dc0e3c5bc63ad9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1679780f482feeb82acb5995587d4fb1d1fe82fd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/18227a6bc98bd0ba96ed3ce9d5b28776a5a28dfc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/36723b28e3293047f087f4501f1ef4ead418dd84"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82fc886e244c76fadf05ef1958aaf8815478ccde"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a72bbb43689591c9d36e3bb45c2d4e688cf92682"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e3d325c0bdb7bc5d1b4cc8d8441d79794cd03729"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fdf06a1b66ff39664b01c6bb6a2aa98d81e8ebe1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72033.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72033"},{"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":"480e3e532e31666a18520a7964bb4095d7a16b9a"},{"fixed":"1679780f482feeb82acb5995587d4fb1d1fe82fd"},{"fixed":"a72bbb43689591c9d36e3bb45c2d4e688cf92682"},{"fixed":"36723b28e3293047f087f4501f1ef4ead418dd84"},{"fixed":"07c05601a9a8e5d4481b2a4a16dc0e3c5bc63ad9"},{"fixed":"fdf06a1b66ff39664b01c6bb6a2aa98d81e8ebe1"},{"fixed":"82fc886e244c76fadf05ef1958aaf8815478ccde"},{"fixed":"e3d325c0bdb7bc5d1b4cc8d8441d79794cd03729"},{"fixed":"18227a6bc98bd0ba96ed3ce9d5b28776a5a28dfc"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72033.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72033.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
