kernel: Bluetooth: L2CAP: Fix possible crash on l2cap_ecred_conn_rsp

A flaw was found in the Bluetooth L2CAP Logical Link Control and Adaptation Protocol component of the Linux kernel. When a device receives a connection response with an already-assigned destination Channel Identifier CID, the system may crash. This occurs because the kernel's procedure for...

kernel: Bluetooth: RFCOMM: hold listener socket in rfcomm_connect_ind()

A flaw was found in the Linux kernel's Bluetooth RFCOMM Radio Frequency Communication subsystem. A race condition in the rfcommconnectind function, specifically during the handling of listener sockets, can lead to a use-after-free vulnerability. A local attacker could exploit this to cause a deni...

kernel: Bluetooth: ISO: fix UAF in iso_recv_frame

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. This vulnerability, known as a Use-After-Free, occurs because the system attempts to use a memory area after it has been released, which can lead to unpredictable behavior. A malicious actor could potentially explo...

kernel: Bluetooth: serialize accept_q access

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition exists in the handling of the acceptq within the btsockpoll function due to a lack of synchronization. This could allow a local attacker to cause a denial of service by manipulating socket operations during child teardow...
