The next list_for_each_entry_continue() from\nthe hitch finds the same resource again, causing an infinite loop.\n\nFix by deferring del_bulk_move to the success path only.\n\nOn the success path, TTM_TT_FLAG_SWAPPED has just been set by\nttm_tt_swapout() but the resource is still tracked in the bulk_move range,\nso ttm_resource_del_bulk_move()'s !ttm_resource_unevictable() guard would\nincorrectly skip the removal. Introduce\nttm_resource_del_bulk_move_unevictable() which bypasses that guard.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-835"],"references":["https://git.kernel.org/stable/c/0124a09e3e5f5f6080efe9663b27af27933f8382","https://git.kernel.org/stable/c/060f8f3020516d71bc4d6159d4d0beef85606a74","https://git.kernel.org/stable/c/b2ed01e7ad3de80333e9b962a44024b094bc0b2b"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-52965","score":0.00172,"percentile":0.06545,"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).
