Looks like the\ncommit missed to remove the existing lock/unlock inside eeh_rmv_device()\nwhich is no longer necessary. This is causing the eehd to hang on the\nlock which it actually holds when that code path is taken.\n\n[<0>] 0xc00000011c78f870\n[<0>] __switch_to+0xfc/0x1a0\n[<0>] pci_lock_rescan_remove+0x30/0x44\n[<0>] eeh_rmv_device+0x290/0x2e0\n[<0>] eeh_pe_dev_traverse+0x80/0x130\n[<0>] eeh_reset_device+0xcc/0x23c\n[<0>] eeh_handle_normal_event+0x830/0xa80\n[<0>] eeh_event_handler+0xf8/0x190\n[<0>] kthread+0x194/0x1b0\n[<0>] start_kernel_thread+0x14/0x18\n\nThe issue is seen for cases where the errors are detected on the PHB\ndirectly AND|OR for devices where the driver error_detected() returns\nPCI_ERS_RESULT_NEED_RESET, and driver being not EEH sensitive(i.e no\nerror handlers like slot_reset(), resume() etc defined).","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/102e3dc5ab5ba052e294819e83384166b242c1ec","https://git.kernel.org/stable/c/24524fca27da674668941440e8e05cdfec0b0222","https://git.kernel.org/stable/c/2920af33d097ca335e492b346af70b72986ad6dc","https://git.kernel.org/stable/c/3833dfae0680b6b16e2469fbc90aa48376311cd8","https://git.kernel.org/stable/c/460fab22b65138531082910702f74b048b25237b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97948","score":0.00176,"percentile":0.0712,"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).
