A crafted NTFS image with circular index node references causes\nunbounded recursion, overflowing the kernel stack and panicking the\nsystem.\n\nThis is reachable by mounting a malicious NTFS filesystem (e.g. from a\nUSB drive via desktop automount) and deleting a file whose index entry\ntriggers the rebalancing fallback path in indx_delete_entry().\n\nAdd a depth parameter and bail out with -EINVAL when it reaches the\nfnd->nodes array bound, matching the constraint already enforced by\nfnd_push() in indx_find().\n\nThe related function indx_find() was previously patched for a similar\ninfinite-loop issue (commit 1732053c8a6b), but indx_find_buffer() was\nmissed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":[],"references":["https://git.kernel.org/stable/c/1ebd684b8f627f75bc3e03f8b2ad8400fd1f02cd","https://git.kernel.org/stable/c/65357a81f64cb3fbe13b4b937586755e4b3a072f","https://git.kernel.org/stable/c/78612f478f9fadcec4f9b3b089970da67ffb47e9","https://git.kernel.org/stable/c/908c9243ba309997b73cbda3e4c563d0fb345ee9","https://git.kernel.org/stable/c/96fb64f9da86fd2dbd78fbe9d9e41ae27e12ce34"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72194","score":0.00798,"percentile":0.56235,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
