In this scenario pin was registered twice,\nso resources are not yet expected to be release until each registered\npin/pin pair is unregistered.\n\nCurrently, the following crash/call trace is produced when ice driver is\nremoved on the system with installed E810T NIC which includes dpll device:\n\nWARNING: CPU: 51 PID: 9155 at drivers/dpll/dpll_core.c:809 dpll_pin_ops+0x20/0x30\nRIP: 0010:dpll_pin_ops+0x20/0x30\nCall Trace:\n ? __warn+0x7f/0x130\n ? dpll_pin_ops+0x20/0x30\n dpll_msg_add_pin_freq+0x37/0x1d0\n dpll_cmd_pin_get_one+0x1c0/0x400\n ? __nlmsg_put+0x63/0x80\n dpll_pin_event_send+0x93/0x140\n dpll_pin_on_pin_unregister+0x3f/0x100\n ice_dpll_deinit_pins+0xa1/0x230 [ice]\n ice_remove+0xf1/0x210 [ice]\n\nFix by adding a parent pointer as a cookie when creating a registration,\nalso when searching for it. For the regular pins pass NULL, this allows to\ncreate separated registration for each parent the pin is registered with.","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/38d7b94e81d068b8d8c8392f421cfd2c3bbfd1a6","https://git.kernel.org/stable/c/f3e1cf62d18220a3aa97e084e7a3552debece9fc","https://git.kernel.org/stable/c/38d7b94e81d068b8d8c8392f421cfd2c3bbfd1a6","https://git.kernel.org/stable/c/f3e1cf62d18220a3aa97e084e7a3552debece9fc"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:50:30.954589733+00:00"},"epss":{"cve":"CVE-2024-36002","score":0.00183,"percentile":0.07875,"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).
