Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec allowing a user to bypass the "access_ok" check and pass a kernel pointer to copy_from_user(). This would allow an attacker to leak information. We recommend upgrading beyond commit 74e19ef0ff8061ef55957c3abd71614ef0f42f47

The Linux Kernel, the operating system core itself. Security Fix(es): A vulnerability was found in the HCI sockets implementation due to a missing capability check in net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of management commands, compromising the confidentiality, integrity, and availability of Bluetooth communication.(CVE-2023-2002) A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11(CVE-2023-0458) In emac_probe, &adpt->work_thread is bound with emac_work_thread. Then it will be started by timeout handler emac_tx_timeout or a IRQ handler emac_isr. If we remove the driver which will call emac_remove to make cleanup, there may be a unfinished work. This could lead to a use-after-free. Upstream fix: https://github.com/torvalds/linux/commit/6b6bc5b8bd2d(CVE-2023-2483) An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order for an attacker to exploit this, the system must have netrom routing configured or the attacker must have the CAP_NET_ADMIN capability.(CVE-2…
