  - In the Linux kernel before 6.1.3, fs/ntfs3/inode.c does not validate the attribute name offset. An     unhandled page fault may occur. (CVE-2022-48424)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176.

  - A use-after-free flaw caused by a race among the superblock operations in the gadgetfs Linux driver was     found. It could be triggered by yanking out a device that is running the gadgetfs side. (CVE-2022-4382)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit     a664ec9158eeddd75121d39c9a0758016097fa96 (CVE-2023-0045)

  - A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel.
    SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result     in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit     56b88b50565cd8b946a2d00b0c83927b7ebb055e (CVE-2023-0266)

  - A use-after-free flaw was found in io_uring/filetable.c in io_install_fixed_file in the io_uring     subcomponent in the Linux Kernel during call cleanup. This flaw may lead to a denial of service.
    (CVE-2023-0469)

  - A use-after-free flaw was found in reconn_set_ipaddr_from_hostname in fs/cifs/connect.c in the Linux     kernel. The issue occurs when it forgets to set the free pointer server->hostname to NULL, leading to an     invalid pointer request. (CVE-2023-1195)

  - In rndis_query_oid in drivers/net/wireless/rndis_wlan.c in the Linux kernel through 6.1.5, there is an     integer overflow in an addition. (CVE-2023-23559)

  - A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks.
    L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after     running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can     execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past     commit 2e7eab81425a (CVE-2022-2196)

  - When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the     sibling thread after an SMT mode switch potentially resulting in information disclosure. (CVE-2022-27672)

  - A use-after-free flaw caused by a race among the superblock operations in the gadgetfs Linux driver was     found. It could be triggered by yanking out a device that is running the gadgetfs side. (CVE-2022-4382)

  - A flaw NULL Pointer Dereference in the Linux kernel NTFS3 driver function attr_punch_hole() was found. A     local user could use this flaw to crash the system. (CVE-2022-4842)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

  - A memory leak flaw was found in the Linux kernel's Stream Control Transmission Protocol. This issue may     occur when a user starts a malicious networking service and someone connects to this service. This could     allow a local user to starve resources, causing a denial of service. (CVE-2023-1074)

  - A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness,     potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field     that overlaps with rec->tx_ready. (CVE-2023-1075)

  - A flaw was found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The     rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user     can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info`     actually points to something else that is potentially controlled by local user. It is known how to trigger     this, which causes an out of bounds access, and a lock corruption. (CVE-2023-1078)

  - Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this     vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS). (CVE-2022-36280)

  - Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC     interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It     appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol     headers are all contained within the linear section of the SKB and some NICs behave badly if this is not     the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x)     though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with     split headers, netback will forward those violating above mentioned assumption to the networking core,     resulting in said misbehavior. (CVE-2022-3643)

  - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused     by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)
