kernel: Bluetooth: RFCOMM: Fix not validating setsockopt user input

This is a vulnerability in the Linux kernel's Bluetooth RFCOMM protocol. It occurs because the rfcommsocksetsockoptold function fails to properly validate the length of user-supplied data, leading to out-of-bounds memory reads. This flaw could result in system instability or crashes...

The vulnerability of the `rfcomm_sock_alloc()` function in the `net/bluetooth/rfcomm/sock.c` module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the rfcommsockalloc function in the net/bluetooth/rfcomm/sock.c module of the Linux operating system is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibili...

The vulnerability of the Linux operating system’s Bluetooth kernel component, which allows a hacker to trigger a service failure

The vulnerability of the Linux operating system’s Bluetooth kernel component is related to incorrect blocking of resources in the function rfcommsockioctl. Exploiting this vulnerability can allow an attacker to cause a service failure...
