As a\nresult if devlink reload is used to reinit the device and then the driver\nis removed, a call trace can occur.\n\nBUG: unable to handle page fault for address: ffffffffc0fd4b5d\nCall Trace:\n string+0x48/0xe0\n vsnprintf+0x1f9/0x650\n sprintf+0x62/0x80\n name_show+0x1f/0x30\n dev_attr_show+0x19/0x60\n\nThe call trace repeats approximately every 10 minutes when system\nmonitoring tools (e.g., sadc) attempt to read the orphaned hwmon sysfs\nattributes that reference freed module memory.\n\nThe sequence is:\n1. Driver load, ice_hwmon_init() gets called from ice_init_feature()\n2. Devlink reload down, flow does not call ice_remove()\n3. Devlink reload up, ice_hwmon_init() gets called from\n   ice_init_feature() resulting in a second instance\n4. Driver unload, ice_hwmon_exit() called from ice_remove() leaving the\n   first hwmon instance orphaned with dangling pointer\n\nFix this by moving ice_hwmon_exit() from ice_remove() to\nice_deinit_features() to ensure proper cleanup symmetry with\nice_hwmon_init().","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":[],"references":["https://git.kernel.org/stable/c/87c1dacca197cc64e06fedeb269e3dd6699bae60","https://git.kernel.org/stable/c/8ac7dd0f813fb65ff2fd9543900c3009f8e84110","https://git.kernel.org/stable/c/d3f867e7a04678640ebcbfb81893c59f4af48586"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-23104","score":0.00135,"percentile":0.02935,"date":"2026-10-31"},"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).
