A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write. This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols functionality in the way a user terminates their session using a simulated Ethernet card and continued usage of this connection. This flaw allows a local user to crash the system. mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel through 5.17.1 has a double free. A double-free flaw was found in the Linux kernel in the ems_usb_start_xmit function. This flaw allows an attacker to create a memory leak and corrupt the underlying data structure by calling free more than once
