kernel: use-after-free in l2cap_sock_release in net/bluetooth/l2cap_sock.c

A flaw was found in l2capsockrelease in net/bluetooth/l2capsock.c in the Bluetooth subsystem in the Linux Kernel. This issue may allow a user to cause a use-after-free problem due to sk's children being mishandled...

kernel: eBPF: insufficient stack type checks in dynptr

An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAPBPF privileges to escalate privileges and...

kernel: UAF during login when accessing the shost ipaddress

A use-after-free flaw was found in iscsiswtcpsessioncreate in drivers/scsi/iscsitcp.c in the SCSI sub-component in the Linux Kernel. This issue could allow an attacker to leak kernel internal information...
