Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a crash when replugging CSR fake controllers in the Linux kernel's Bluetooth component. It seems that fake CSR 5.0 clones can cause the suspend notifier to be registered twice, leading to a kernel panic. The vulnerability is also related to incorrect locking in the io tctx exit cb() function in io uring/io uring.c, which can allow an attacker to cause a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
