CVE-2024-46680 is fixed in 26 products on 1 platform, first by DEBIAN-CVE-2024-46680, released September 13, 2024. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2024-46680 - Priority: Routine - CVSS: 5.5 (medium) - EPSS: 0.0025 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Sep 13, 2024 ## Description In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btnxpuart: Fix random crash seen while removing driver This fixes the random kernel crash seen while removing the driver, when running the load/unload test over multiple iterations. 1) modprobe btnxpuart 2) hciconfig hci0 reset 3) hciconfig (check hci0 interface up with valid BD address) 4) modprobe -r btnxpuart Repeat steps 1 to 4 The ps_wakeup() call in btnxpuart_close() schedules the psdata->work(), which gets scheduled after module is removed, causing a kernel crash. This hidden issue got highlighted after enabling Power Save by default in 4183a7be7700 (Bluetooth: btnxpuart: Enable Power Save feature on startup) The new ps_cleanup() deasserts UART break immediately while closing serdev device, cancels any scheduled ps_work and destroys the ps_lock mutex.
