But if CONFIG_INIT_ON_FREE_DEFAULT_ON\nis set to yes, kernel panic will happen:\nCall trace:\n destroy_workqueue+0x1c/0x258\n ath10k_sdio_remove+0x84/0x94\n sdio_bus_remove+0x50/0x16c\n device_release_driver_internal+0x188/0x25c\n device_driver_detach+0x20/0x2c\n\nThis is because during 'rmmod ath10k', ath10k_sdio_remove() will call\nath10k_core_destroy() before destroy_workqueue(). wiphy_dev_release()\nwill finally be called in ath10k_core_destroy(). This function will free\nstruct cfg80211_registered_device *rdev and all its members, including\nwiphy, dev and the pointer of sdio workqueue. Then the pointer of sdio\nworkqueue will be set to NULL due to CONFIG_INIT_ON_FREE_DEFAULT_ON.\n\nAfter device release, destroy_workqueue() will use NULL pointer then the\nkernel panic happen.\n\nCall trace:\nath10k_sdio_remove\n ->ath10k_core_unregister\n ……\n ->ath10k_core_stop\n ->ath10k_hif_stop\n ->ath10k_sdio_irq_disable\n ->ath10k_hif_power_down\n ->del_timer_sync(&ar_sdio->sleep_timer)\n ->ath10k_core_destroy\n ->ath10k_mac_destroy\n ->ieee80211_free_hw\n ->wiphy_free\n ……\n ->wiphy_dev_release\n ->destroy_workqueue\n\nNeed to call destroy_workqueue() before ath10k_core_destroy(), free\nthe work queue buffer first and then free pointer of work queue by\nath10k_core_destroy(). This order matches the error path order in\nath10k_sdio_probe().\n\nNo work will be queued on sdio workqueue between it is destroyed and\nath10k_core_destroy() is called. Based on the call_stack above, the\nreason is:\nOnly ath10k_sdio_sleep_timer_handler(), ath10k_sdio_hif_tx_sg() and\nath10k_sdio_irq_disable() will queue work on sdio workqueue.\nSleep timer will be deleted before ath10k_core_destroy() in\nath10k_hif_power_down().\nath10k_sdio_irq_disable() only be called in ath10k_hif_stop().\nath10k_core_unregister() will call ath10k_hif_power_down() to stop hif\nbus, so ath10k_sdio_hif_tx_sg() won't be called anymore.\n\nTested-on: QCA6174 hw3.2 SDIO WLAN.RMH.4.4.1-00189" } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/ath/ath10k/sdio.c" ], "versions": [ { "version": "5e3dd157d7e70f0e3cea3f2573ed69fb156a19d5", "lessThan": "27d5d217ae7ffb99dd623375a17a7d3418d9c755", "status": "affected", "versionType": "git" }, { "version": "5e3dd157d7e70f0e3cea3f2573ed69fb156a19d5", "lessThan": "27fda36eedad9e4ec795dc481f307901d1885112", "status": "affected", "versionType": "git" }, { "version": "5e3dd157d7e70f0e3cea3f2573ed69fb156a19d5", "lessThan": "6e5dbd1c04abf2c19b2282915e6fa48b6ccc6921", "status": "affected", "versionType": "git" }, { "version": "5e3dd157d7e70f0e3cea3f2573ed69fb156a19d5", "lessThan": "b35de9e01fc79c7baac666fb2dcb4ba7698a1d97", "status": "affected", "versionType": "git" }, { "version": "5e3dd157d7e70f0e3cea3f2573ed69fb156a19d5", "lessThan": "543c0924d446b21f35701ca084d7feca09511220", "status": "affected", "versionType": "git" }, { "version": "5e3dd157d7e70f0e3cea3f2573ed69fb156a19d5", "lessThan": "95c38953cb1ecf40399a676a1f85dfe2b5780a9a", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/ath/ath10k/sdio.c" ], "versions": [ { "version": "3.11", "status": "affected" }, { "version": "0", "lessThan": "3.11", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.237", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.181", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.127", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.70", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.5", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.13", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "5.10.237" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "5.15.181" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.1.127" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.6.70" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.12.5" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.13" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/27d5d217ae7ffb99dd623375a17a7d3418d9c755" }, { "url": "https://git.kernel.org/stable/c/27fda36eedad9e4ec795dc481f307901d1885112" }, { "url": "https://git.kernel.org/stable/c/6e5dbd1c04abf2c19b2282915e6fa48b6ccc6921" }, { "url": "https://git.kernel.org/stable/c/b35de9e01fc79c7baac666fb2dcb4ba7698a1d97" }, { "url": "https://git.kernel.org/stable/c/543c0924d446b21f35701ca084d7feca09511220" }, { "url": "https://git.kernel.org/stable/c/95c38953cb1ecf40399a676a1f85dfe2b5780a9a" } ], "title": "wifi: ath10k: avoid NULL pointer error during sdio remove", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html" }, { "url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T20:50:35.314Z" } } ] } }
