Description
A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. A call to btsdio_remove with an unfinished job may cause a race problem which leads to a UAF on hdev devices.

Remediation

Vendor Workaround

This flaw can be mitigated by preventing the affected Generic Bluetooth SDIO driver kernel module from loading during the boot time. Ensure the module is added into the blacklist file. ~~~ Refer: How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278 ~~~
