    In the Linux kernel, the following vulnerability has been resolved: x86/kvm: Disable kvmclock on all CPUs
    on shutdown Currenly, we disable kvmclock from machine_shutdown() hook and this only happens for boot CPU.
    We need to disable it for all CPUs to guard against memory corruption e.g. on restore from hibernate.
    Note, writing '0' to kvmclock MSR doesn't clear memory location, it just prevents hypervisor from updating
    the location so for the short while after write and while CPU is still alive, the clock remains usable and
    correct so we don't need to switch to some other clocksource.(CVE-2021-47110)

    In the Linux kernel, the following vulnerability has been resolved: ceph: fix deadlock or deadcode of
    misusing dget() The lock order is incorrect between denty and its parent, we should always make sure that
    the parent get the lock first. But since this deadcode is never used and the parent dir will always be set
    from the callers, let's just remove it.(CVE-2023-52583)

    In the Linux kernel, the following vulnerability has been resolved: drm: Don't unref the same fb many
    times by mistake due to deadlock handling If we get a deadlock after the fb lookup in
    drm_mode_page_flip_ioctl() we proceed to unref the fb and then retry the whole thing from the top. But we
    forget to reset the fb pointer back to NULL, and so if we then get another error during the retry, before
    the fb lookup, we proceed the unref the same fb again without having gotten another reference. The end
    result is that the fb will (eventually) end up being freed while it's still in use. Reset fb to NULL once
    we've unreffed it to avoid doing it again until we've done another fb lookup. This turned out to be pretty
    easy to hit on a DG2 when doing async flips (and CONFIG_DEBUG_WW_MUTEX_SLOWPATH=y). The first symptom I
    saw that drm_closefb() simply got stuck in a busy loop while walking the framebuffer list. Fortunately I
    was able to convince it to oops instead, and from there it was easier to track down the
    culprit.(CVE-2023-52486)

    In the Linux kernel, the following vulnerability has been resolved: perf/x86/lbr: Filter vsyscall
    addresses We found that a panic can occur when a vsyscall is made while LBR sampling is active. If the
    vsyscall is interrupted (NMI) for perf sampling, this call sequence can occur (most recent at top):
    __insn_get_emulate_prefix() insn_get_emulate_prefix() insn_get_prefixes() insn_get_opcode()
    decode_branch_type() get_branch_type() intel_pmu_lbr_filter() intel_pmu_handle_irq()
    perf_event_nmi_handler() Within __insn_get_emulate_prefix() at frame 0, a macro is called:
    peek_nbyte_next(insn_byte_t, insn, i) Within this macro, this dereference occurs: (insn)-next_byte
    Inspecting registers at this point, the value of the next_byte field is the address of the vsyscall made,
    for example the location of the vsyscall version of gettimeofday() at 0xffffffffff600000. The access to an
    address in the vsyscall region will trigger an oops due to an unhandled page fault. To fix the bug,
    filtering for vsyscalls can be done when determining the branch type. This patch will return a 'none'
    branch if a kernel address if found to lie in the vsyscall region.(CVE-2023-52476)

    In the Linux kernel, the following vulnerability has been resolved: HID: logitech-hidpp: Fix kernel crash
    on receiver USB disconnect hidpp_connect_event() has *four* time-of-check vs time-of-use (TOCTOU) races
    when it races with itself. hidpp_connect_event() primarily runs from a workqueue but it also runs on
    probe() and if a 'device-connected' packet is received by the hw when the thread running
    hidpp_connect_event() from probe() is waiting on the hw, then a second thread running
    hidpp_connect_event() will be started from the workqueue. This opens the following races (note the below
    code is simplified): 1. Retrieving + printing the protocol (harmless race): if (!hidpp-protocol_major)
    { hidpp_root_get_protocol_version() hidpp-protocol_major = response.rap.params[0]; } We can actually
    see this race hit in the dmesg in the abrt output attached to rhbz#2227968: [ 3064.624215] logitech-hidpp-
    device 0003:046D:4071.0049: HID++ 4.5 device connected. [ 3064.658184] logitech-hidpp-device
    0003:046D:4071.0049: HID++ 4.5 device connected. Testing with extra logging added has shown that after
    this the 2 threads take turn grabbing the hw access mutex (send_mutex) so they ping-pong through all the
    other TOCTOU cases managing to hit all of them: 2. Updating the name to the HIDPP name (harmless race): if
    (hidpp-name == hdev-name) { ... hidpp-name = new_name; } 3. Initializing the power_supply class
    for the battery (problematic!): hidpp_initialize_battery() { if (hidpp-battery.ps) return 0;
    probe_battery(); /* Blocks, threads take turns executing this */ hidpp-battery.desc.properties =
    devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL); hidpp-battery.ps =
    devm_power_supply_register(hidpp-hid_dev-dev, hidpp-battery.desc, cfg); } 4. Creating
    delayed input_device (potentially problematic): if (hidpp-delayed_input) return; hidpp-delayed_input
    = hidpp_allocate_input(hdev); The really big problem here is 3. Hitting the race leads to the following
    sequence: hidpp-battery.desc.properties = devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL);
    hidpp-battery.ps = devm_power_supply_register(hidpp-hid_dev-dev, hidpp-battery.desc,
    cfg); ... hidpp-battery.desc.properties = devm_kmemdup(dev, hidpp_battery_props, cnt, GFP_KERNEL);
    hidpp-battery.ps = devm_power_supply_register(hidpp-hid_dev-dev, hidpp-battery.desc,
    cfg); So now we have registered 2 power supplies for the same battery, which looks a bit weird from
    userspace's pov but this is not even the really big problem. Notice how: 1. This is all devm-maganaged 2.
    The hidpp-battery.desc struct is shared between the 2 power supplies 3. hidpp-
    battery.desc.properties points to the result from the second devm_kmemdup() This causes a use after
    free scenario on USB disconnect of the receiver: 1. The last registered power supply class device gets
    unregistered 2. The memory from the last devm_kmemdup() call gets freed, hidpp-battery.desc.properties
    now points to freed memory 3. The first registered power supply class device gets unregistered, this
    involves sending a remove uevent to userspace which invokes power_supply_uevent() to fill the uevent data
    4. power_supply_uevent() uses hidpp-battery.desc.properties which now points to freed memory leading to
    backtraces like this one: Sep 22 20:01:35 eric kernel: BUG: unable to handle page fault for address:

    In the Linux kernel, the following vulnerability has been resolved: i2c: Fix a potential use after free
    Free the adap structure only after we are done using it. This patch just moves the put_device() down a bit
    to avoid the use after free. (CVE-2019-25162)

    In the Linux kernel, the following vulnerability has been resolved:vt: fix memory overlapping when
    deleting chars in the buffer.A memory overlapping copy occurs when deleting a long line. This memory
    overlapping copy can cause data corruption when scr_memcpyw is optimized to memcpy because memcpy does not
    ensure its behavior if the destination buffer overlaps with the source buffer. The line buffer is not
    always broken, because the memcpy utilizes the hardware acceleration, whose result is not
    deterministic.Fix this problem by using replacing the scr_memcpyw with scr_memmovew.(CVE-2022-48627)

    In the Linux kernel, the following vulnerability has been resolved:wifi: mac80211: fix potential key use-
    after-free.When ieee80211_key_link() is called by ieee80211_gtk_rekey_add() but returns 0 due to KRACK
    protection (identical key reinstall),ieee80211_gtk_rekey_add() will still return a pointer into the key,
    in a potential use-after-free. This normally doesn't happen since it's only called by iwlwifi in case of
    WoWLAN rekey offload which has its own KRACK protection, but still better to fix, do that by returning an
    error code and converting that to success on the cfg80211 boundary only, leaving the error for bad callers
    of ieee80211_gtk_rekey_add().(CVE-2023-52530)

    as an argument to rtw_get_channel_group() and set the group for channel 14 to 4 if rate = DESC_RATE11M.
    This patch fixes commit fa6dfe6bff24 ('rtw88: resolve order of tx power setting routines')(CVE-2021-47065)

    In the Linux kernel, the following vulnerability has been resolved: Input: powermate - fix use-after-free
    in powermate_config_complete syzbot has found a use-after-free bug [1] in the powermate driver. This
    happens when the device is disconnected, which leads to a memory free from the powermate_device struct.
    When an asynchronous control message completes after the kfree and its callback is invoked, the lock does
    not exist anymore and hence the bug. Use usb_kill_urb() on pm-config to cancel any in-progress requests
    upon device disconnection.(CVE-2023-52475)

    In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Clear all QP fields if

    In the Linux kernel, the following vulnerability has been resolved: net: fix possible store tearing in
    neigh_periodic_work() While looking at a related syzbot report involving neigh_periodic_work(), I found
    that I forgot to add an annotation when deleting an RCU protected item from a list. Readers use
    rcu_deference(*np), we need to use either rcu_assign_pointer() or WRITE_ONCE() on writer side to prevent
    store tearing. I use rcu_assign_pointer() to have lockdep support, this was the choice made in
    neigh_flush_dev().(CVE-2023-52522)

    In the Linux kernel, the following vulnerability has been resolved: uio_hv_generic: Fix a memory leak in

    defined with cpu_feature_enabled(). KASAN gets confused when apply_alternatives() patches the
    KASAN_SHADOW_START users. A test patch that makes KASAN_SHADOW_START static, by replacing
    __VIRTUAL_MASK_SHIFT with 56, works around the issue. Fix it for real by disabling KASAN while the kernel
    is patching alternatives.(CVE-2023-52504)

    In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix RX consumer index logic

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to
    achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error
    within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when
    NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit
    f342de4e2f33e0e39165d8639387aa6c19dff660.(CVE-2024-1086)

    In the Linux kernel, the following vulnerability has been resolved: nvme-loop: fix memory leak in
    nvme_loop_create_ctrl() When creating loop ctrl in nvme_loop_create_ctrl(), if nvme_init_ctrl() fails, the
    loop ctrl should be freed before jumping to the 'out' label.(CVE-2021-47074)

    In the Linux kernel, the following vulnerability has been resolved: ARM: 9064/1: hw_breakpoint: Do not
    directly check the event's overflow_handler hook The commit 1879445dfa7b ('perf/core: Set event's default

    check event-overflow_handler with is_default_overflow_handler(), but one is missing. Currently, the bp-
    overflow_handler can not be NULL. As a result, enable_single_step() is always not invoked. Comments

    In the Linux kernel, the following vulnerability has been resolved: crypto: qat - ADF_STATUS_PF_RUNNING
    should be set after adf_dev_init ADF_STATUS_PF_RUNNING is (only) used and checked by adf_vf2pf_shutdown()
    before calling adf_iov_putmsg()-mutex_lock(vf2pf_lock), however the vf2pf_lock is initialized in
    adf_dev_init(), which can fail and when it fail, the vf2pf_lock is either not initialized or destroyed, a
    subsequent use of vf2pf_lock will cause issue. To fix this issue, only set this flag if adf_dev_init()
    returns 0. [ 7.178404] BUG: KASAN: user-memory-access in __mutex_lock.isra.(CVE-2021-47056)

    In the Linux kernel, the following vulnerability has been resolved: drm: bridge/panel: Cleanup connector
    on bridge detach If we don't call drm_connector_cleanup() manually in panel_bridge_detach(), the connector
    will be cleaned up with the other DRM objects in the call to drm_mode_config_cleanup(). However, since our
    drm_connector is devm-allocated, by the time drm_mode_config_cleanup() will be called, our connector will
    be long gone. Therefore, the connector must be cleaned up when the bridge is detached to avoid use-after-
    free conditions.(CVE-2021-47063)

    In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fix info leak in
    hid_submit_ctrl In hid_submit_ctrl(), the way of calculating the report length doesn't take into account
    that report-size can be zero. When running the syzkaller reproducer, a report of size 0 causes
    hid_submit_ctrl) to calculate transfer_buffer_length as 16384. When this urb is passed to the usb core
    layer, KMSAN reports an info leak of 16384 bytes. To fix this, first modify hid_report_len() to account
    for the zero report size case by using DIV_ROUND_UP for the division. Then, call it from
    hid_submit_ctrl().(CVE-2021-46906)

    A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a
    recursive operation of code push recursively calls into the code block. The OVS module does not validate
    the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a
    crash or other related issues.(CVE-2024-1151)

    In the Linux kernel, the following vulnerability has been resolved: NFS: fs_context: validate UDP retrans
    to prevent shift out-of-bounds Fix shift out-of-bounds in xprt_calc_majortimeo(). This is caused by a
    garbage timeout (retrans) mount option being passed to nfs mount, in this case from syzkaller. If the
    protocol is XPRT_TRANSPORT_UDP, then 'retrans' is a shift value for a 64-bit long integer, so 'retrans'
    cannot be = 64. If it is = 64, fail the mount and return an error.(CVE-2021-46952)

    In the Linux kernel, the following vulnerability has been resolved: KVM: Destroy I/O bus devices on
    unregister failure _after_ sync'ing SRCU If allocating a new instance of an I/O bus fails when
    unregistering a device, wait to destroy the device until after all readers are guaranteed to see the new
    null bus. Destroying devices before the bus is nullified could lead to use-after-free since readers expect
    the devices on their reference of the bus to remain valid.(CVE-2021-47061)

    In the Linux kernel, the following vulnerability has been resolved: usb: hub: Guard against accesses to

    fields inside udev-bos without checking if it was allocated and initialized. If
    usb_get_bos_descriptor() fails for whatever reason, udev-bos will be NULL and those accesses will
    result in a crash: BUG: kernel NULL pointer dereference, address: 0000000000000018 PGD 0 P4D 0 Oops: 0000

    for IPv4 packets, ovs_fragment() uses a temporary struct dst_entry. Then, in the following call graph:
    ip_do_fragment() ip_skb_dst_mtu() ip_dst_mtu_maybe_forward() ip_mtu_locked() the pointer to struct
    dst_entry is used as pointer to struct rtable: this turns the access to struct members like rt_mtu_locked
    into an OOB read in the stack. Fix this changing the temporary variable used for IPv4 packets in
    ovs_fragment(), similarly to what is done for IPv6 few lines below.(CVE-2021-46955)

    In the Linux kernel, the following vulnerability has been resolved: media: pvrusb2: fix use after free on
    context disconnection Upon module load, a kthread is created targeting the pvr2_context_thread_func
    function, which may call pvr2_context_destroy and thus call kfree() on the context object. However, that
    might happen before the usb hub_event handler is able to notify the driver. This patch adds a sanity check
    before the invalid read reported by syzbot, within the context disconnection call stack.(CVE-2023-52445)

    In the Linux kernel, the following vulnerability has been resolved: net: hso: fix null-ptr-deref during
    tty device unregistration Multiple ttys try to claim the same the minor number causing a double
    unregistration of the same device. The first unregistration succeeds but the next one results in a null-
    ptr-deref. The get_free_serial_index() function returns an available minor number but doesn't assign it
    immediately. The assignment is done by the caller later. But before this assignment, calls to
    get_free_serial_index() would return the same minor number. Fix this by modifying get_free_serial_index to
    assign the minor number immediately after one is found to be and rename it to obtain_minor() to better
    reflect what it does. Similary, rename set_serial_by_index() to release_minor() and modify it to free up
    the minor number of the given hso_serial. Every obtain_minor() should have corresponding release_minor()
    call.(CVE-2021-46904)

    In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix stack
    corruption When tc filters are first added to a net device, the corresponding local port gets bound to an
    ACL group in the device. The group contains a list of ACLs. In turn, each ACL points to a different TCAM
    region where the filters are stored. During forwarding, the ACLs are sequentially evaluated until a match
    is found. One reason to place filters in different regions is when they are added with decreasing
    priorities and in an alternating order so that two consecutive filters can never fit in the same region
    because of their key usage. In Spectrum-2 and newer ASICs the firmware started to report that the maximum
    number of ACLs in a group is more than 16, but the layout of the register that configures ACL groups
    (PAGT) was not updated to account for that. It is therefore possible to hit stack corruption [1] in the
    rare case where more than 16 ACLs in a group are required. Fix by limiting the maximum ACL group size to
    the minimum between what the firmware reports and the maximum ACLs that fit in the PAGT register. Add a
    test case to make sure the machine does not crash when this condition is hit. [1] Kernel panic - not

    In the Linux kernel, the following vulnerability has been resolved: parisc: Clear stale IIR value on
    instruction access rights trap When a trap 7 (Instruction access rights) occurs, this means the CPU
    couldn't execute an instruction due to missing execute permissions on the memory region. In this case it
    seems the CPU didn't even fetched the instruction from memory and thus did not store it in the cr19 (IIR)
    register before calling the trap handler. So, the trap handler will find some random old stale value in
    cr19. This patch simply overwrites the stale IIR value with a constant magic 'bad food' value
    (0xbaadf00d), in the hope people don't start to try to understand the various random IIR values in trap 7
    dumps.(CVE-2021-46928)

    In the Linux kernel, the following vulnerability has been resolved: net: hso: fix NULL-deref on disconnect
    regression Commit 8a12f8836145 ('net: hso: fix null-ptr-deref during tty device unregistration') fixed the
    racy minor allocation reported by syzbot, but introduced an unconditional NULL-pointer dereference on
    every disconnect instead. Specifically, the serial device table must no longer be accessed after the minor
    has been released by hso_serial_tty_unregister().(CVE-2021-46905)

    In the Linux kernel, the following vulnerability has been resolved: block: add check that partition length
    needs to be aligned with block size Before calling add partition or resize partition, there is no check on
    whether the length is aligned with the logical block size. If the logical block size of the disk is larger
    than 512 bytes, then the partition size maybe not the multiple of the logical block size, and when the
    last sector is read, bio_truncate() will adjust the bio size, resulting in an IO error if the size of the
    read command is smaller than the logical block size.If integrity data is supported, this will also result
    in a null pointer dereference when calling bio_integrity_free.(CVE-2023-52458)

    In the Linux kernel, the following vulnerability has been resolved: tls: fix race between tx work
    scheduling and socket close Similarly to previous commit, the submitting thread (recvmsg/sendmsg) may exit
    as soon as the async crypto handler calls complete(). Reorder scheduling the work before calling
    complete(). This seems more logical in the first place, as it's the inverse order of what the submitting
    thread will do.(CVE-2024-26585)

    In the Linux kernel, the following vulnerability has been resolved: net: prevent mss overflow in
    skb_segment() Once again syzbot is able to crash the kernel in skb_segment() [1] GSO_BY_FRAGS is a
    forbidden value, but unfortunately the following computation in skb_segment() can reach it quite easily :
    mss = mss * partial_segs; 65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to a bad final
    result. Make sure to limit segmentation so that the new mss value is smaller than GSO_BY_FRAGS. [1]

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to
    achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error
    within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when
    NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit
    f342de4e2f33e0e39165d8639387aa6c19dff660.(CVE-2024-1086)

    Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows

    5.10.0-60.18.0 before 5.10.0-183.0.0.(CVE-2021-33631)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval()
    function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes
    are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every
    iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local
    user to cause a denial of service or potentially break NetFilter functionality.(CVE-2024-0607)

    A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in
    net/sctp/socket.c in the Linux kernels SCTP subsystem. This flaw allows guests with local user
    privileges to trigger a deadlock and potentially crash the system.(CVE-2024-0639)
