In the Linux kernel, the following vulnerability has been resolved: tracing: Restructure trace_clock_global() to never block It was reported that a fix to the ring buffer recursion detection would cause a hung machine when performing suspend / resume testing. The following backtrace was extracted from debugging that case: Call Trace: trace_clock_global+0x91/0xa0 __rb_reserve_next+0x237/0x460 ring_buffer_lock_reserve+0x12a/0x3f0 trace_buffer_lock_reserve+0x10/0x50 __trace_graph_return+0x1f/0x80 trace_graph_return+0xb7/0xf0 ? trace_clock_global+0x91/0xa0 ftrace_return_to_handler+0x8b/0xf0 ? pv_hash+0xa0/0xa0 return_to_handler+0x15/0x30 ? ftrace_graph_caller+0xa0/0xa0 ? trace_clock_global+0x91/0xa0 ? __rb_reserve_next+0x237/0x460 ? ring_buffer_lock_reserve+0x12a/0x3f0 ? trace_event_buffer_lock_reserve+0x3c/0x120 ? trace_event_buffer_reserve+0x6b/0xc0 ? trace_event_raw_event_device_pm_callback_start+0x125/0x2d0 ? dpm_run_callback+0x3b/0xc0 ? pm_ops_is_empty+0x50/0x50 ? platform_get_irq_byname_optional+0x90/0x90 ? trace_device_pm_callback_start+0x82/0xd0 ? dpm_run_callback+0x49/0xc0 With the following RIP: RIP: 0010:native_queued_spin_lock_slowpath+0x69/0x200 Since the fix to the recursion detection would allow a single recursion to happen while tracing, this lead to the trace_clock_global() taking a spin lock and then trying to take it again: ring_buffer_lock_reserve() { trace_clock_global() { arch_spin_lock() { queued_spin_lock_slowpath() { /* lock taken */ (something else gets traced by function graph tracer) ring_buffer_lock_reserve() { trace_clock_global() { arch_spin_lock() { queued_spin_lock_slowpath() { /* DEAD LOCK! */ Tracing should *never* block, as it can lead to strange lockups like the above. Restructure the trace_clock_global() code to instead of simply taking a lock to update the recorded "prev_time" simply use it, as two events happening on two different CPUs that calls this at the same time, really doesn't matter which one goes first. Use a trylock to grab the lock for updating the prev_time, and if it fails, simply try again the next time. If it failed to be taken, that means something else is already updating it.

  - In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix double free of the     ha->vp_map pointer Coverity scan reported potential risk of double free of the pointer ha->vp_map.
    ha->vp_map was freed in qla2x00_mem_alloc(), and again freed in function qla2x00_mem_free(ha). Assign NULL     to vp_map and kfree take care of NULL. (CVE-2024-26930)

  - In the Linux kernel, the following vulnerability has been resolved: netlabel: fix out-of-bounds memory     accesses There are two array out-of-bounds memory accesses, one in cipso_v4_map_lvl_valid(), the other in     netlbl_bitmap_walk(). Both errors are embarassingly simple, and the fixes are straightforward. As a FYI     for anyone backporting this patch to kernels prior to v4.8, you'll want to apply the netlbl_bitmap_walk()     patch to cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn't exist before Linux v4.8. (CVE-2019-25160)

    A flaw was found in the Linux kernels implementation of wifi fragmentation handling. An attacker with the     ability to transmit within the wireless transmission range of an access point can abuse a flaw where     previous contents of wifi fragments can be unintentionally transmitted to another device. (CVE-2020-24586)

    A flaw was found in the Linux kernel's WiFi implementation. An attacker within the wireless range can     abuse a logic flaw in the WiFi implementation by reassembling packets from multiple fragments under     different keys, treating them as valid. This flaw allows an attacker to send a fragment under an incorrect     key, treating them as a valid fragment under the new key. The highest threat from this vulnerability is to     confidentiality. (CVE-2020-24587)

    A flaw was found in the Linux kernels wifi implementation. An attacker within wireless broadcast range can     inject custom data into the wireless communication circumventing checks on the data.  This can cause the     frame to pass checks and be considered a valid frame of a different type. (CVE-2020-24588)

If a netdev goes up, while the connection is still active, and     the data flow resumes after a number of TCP retransmissions, it will lead to a use-after-free of the TLS     context. This commit addresses this bug by keeping the context alive until its normal destruction, and     implements the necessary fallbacks, so that the connection can resume in software (non-offloaded) kTLS     mode.

    2024-03-13: CVE-2021-46906 was added to this advisory.

    A vulnerability was found in the bluez, where Passkey Entry protocol used in Secure Simple Pairing (SSP),     Secure Connections (SC) and LE Secure Connections (LESC) of the Bluetooth Core Specification is vulnerable     to an impersonation attack where an active attacker can impersonate the initiating device without any     previous knowledge. (CVE-2020-26558)

    A flaw was found in the Linux kernel. Improper access control in BlueZ may allow an authenticated user to     potentially enable information disclosure via adjacent access. The highest threat from this vulnerability     is to data confidentiality and integrity. (CVE-2021-0129)

    A denial-of-service (DoS) flaw was identified  in the Linux kernel due to an incorrect memory barrier in     xt_replace_table in net/netfilter/x_tables.c in the netfilter subsystem. (CVE-2021-29650)

    A flaw was found in the Linux kernel's handling of the removal of Bluetooth HCI controllers. This flaw     allows an attacker with a local account to exploit a race condition, leading to corrupted memory and     possible privilege escalation. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-32399)

    A use-after-free flaw was found in hci_send_acl in the bluetooth host controller interface (HCI) in Linux     kernel, where a local attacker with an access rights could cause a denial of service problem on the system     The issue results from the object hchan, freed in hci_disconn_loglink_complete_evt, yet still used in     other places. The highest threat from this vulnerability is to data integrity, confidentiality and system     availability. (CVE-2021-33034)

    In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because     of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a     side-channel attack, aka CID-9183671af6db. (CVE-2021-33624)

    A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in     the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the     system. (CVE-2021-3564)

    A flaw use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in     the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call     hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(),     hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system     or escalate their privileges on the system. (CVE-2021-3573)

    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'ttake into account that report->size     can be zero. When running thesyzkaller reproducer, a report of size 0 causes hid_submit_ctrl) tocalculate     transfer_buffer_length as 16384. When this urb is passed tothe usb core layer, KMSAN reports an info leak     of 16384 bytes.

    To fix this, first modify hid_report_len() to account for the zeroreport size case by using DIV_ROUND_UP     for the division. Then, call itfrom hid_submit_ctrl(). (CVE-2021-46906)

    In the Linux kernel, the following vulnerability has been resolved:

    dm rq: fix double free of blk_mq_tag_set in dev remove after table load fails (CVE-2021-46938)

    In the Linux kernel, the following vulnerability has been resolved:

    tracing: Restructure trace_clock_global() to never block (CVE-2021-46939)

    In the Linux kernel, the following vulnerability has been resolved:

    md/raid1: properly indicate failure when ending a failed write request

    This patch addresses a data corruption bug in raid1 arrays using bitmaps.Without this fix, the bitmap bits     for the failed I/O end up being cleared.

    Since we are in the failure leg of raid1_end_write_request, the requesteither needs to be retried     (R1BIO_WriteError) or failed (R1BIO_Degraded). (CVE-2021-46950)

    In the Linux kernel, the following vulnerability has been resolved:

    ACPI: GTDT: Don't corrupt interrupt mappings on watchdow probe failure (CVE-2021-46953)

    In the Linux kernel, the following vulnerability has been resolved:

    openvswitch: fix stack OOB read while fragmenting IPv4 packets (CVE-2021-46955)
