{"id":"DEBIAN-CVE-2023-53565","details":"In the Linux kernel, the following vulnerability has been resolved:  wifi: brcmfmac: Check for probe() id argument being NULL  The probe() id argument may be NULL in 2 scenarios:  1. brcmf_pcie_pm_leave_D3() calling brcmf_pcie_probe() to reprobe    the device.  2. If a user tries to manually bind the driver from sysfs then the sdio /    pcie / usb probe() function gets called with NULL as id argument.  1. Is being hit by users causing the following oops on resume and causing wifi to stop working:  BUG: kernel NULL pointer dereference, address: 0000000000000018 \u003csnip\u003e Hardware name: Dell Inc.

In the PCI and USB cases try a manual lookup of the id so that manually binding the driver through sysfs and more importantly brcmf_pcie_probe() on resume will work.  For the SDIO case there is no helper to do a manual sdio_device_id lookup, so just directly error out on a NULL id there.","modified":"2026-09-15T09:02:46.181333864Z","published":"2025-10-04T16:15:51.987Z","upstream":["CVE-2023-53565"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-53565"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.3.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-53565.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.3.7-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-53565.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
