Kernel: double free in hci_conn_cleanup of the bluetooth subsystem

A double-free vulnerability was found in the hciconncleanup in net/bluetooth/hciconn.c in the Linux Kernel. This issue may cause a denial of service or privilege escalation...

kernel: xfrm: out-of-bounds read in __xfrm_state_filter_match()

A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local privileged CAPNETADMIN attacker to trigger an out-of-bounds read, potentially leadi...

kernel: bluetooth: bt_sock_ioctl race condition leads to use-after-free in bt_sock_recvmsg

A flaw was found in the Bluetooth subsystem of the Linux kernel. A race condition between the btsockrecvmsg and btsockioctl functions could lead to a use-after-free on a socket buffer "skb". This flaw allows a local user to cause a denial of service condition or potential code execution...
