In the Linux kernel, the following vulnerability has been resolved: net/tls: Fix use-after-free after the TLS device goes down and up When a netdev with active TLS offload goes down, tls_device_down is called to stop the offload and tear down the TLS context. However, the socket stays alive, and it still points to the TLS context, which is now deallocated. 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. On the TX side tls_sw_fallback is used to encrypt all packets. The RX side already has all the necessary fallbacks, because receiving non-decrypted packets is supported. The thing needed on the RX side is to block resync requests, which are normally produced after receiving non-decrypted packets. The necessary synchronization is implemented for a graceful teardown: first the fallbacks are deployed, then the driver resources are released (it used to be possible to have a tls_dev_resync after tls_dev_del). A new flag called TLS_RX_DEV_DEGRADED is added to indicate the fallback mode. It's used to skip the RX resync logic completely, as it becomes useless, and some objects may be released (for example, resync_async, which is allocated and freed by the driver).

    Use explicit argument to prevent continuation with empty cve2bugzilla file.

Therefore use the timestamp of the whole packed-ref file (better     false positive detection of update than breakage or false negative). Add unified approach to read packed-     refs regardless of KSOURCE_GIT worktree or not.
    - mass-cve: Make BRANCH mandatory
    - mass-cve: Use dedicated worktree for reference updates So that any checkout in KSOURCE_GIT is not     changed.

    - scripts/check-kernel-fix: avoid rechecking child branches when parents are OK Topological sorted     dependency tree allows to optimize check-kernel-fixe in cases where parent already has the fix. There is     not reason to check branches which merge from that branch as they will get the fix eventually.
    - scripts/check-kernel-fix: print a message when no action is needed. Script exits without printing     anything about the actions necessary in non-verbose mode. This can be confusing to a beginner user.
    - scripts/common-functions: for_each_build_branch traverse branches in dependency topo sorted list

    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)

    Frames used for authentication and key management between the AP and connected clients.  Some clients may     take these redirected frames masquerading as control mechanisms from the AP. (CVE-2020-26139)

    A vulnerability was found in Linux kernel's WiFi implementation.  An attacker within wireless range can     inject a control packet fragment where the kernel does not verify the Message Integrity Check     (authenticity) of fragmented TKIP frames. (CVE-2020-26141)

    A flaw was found in ath10k_htt_rx_proc_rx_frag_ind_hl in drivers/net/wireless/ath/ath10k/htt_rx.c in the     Linux kernel WiFi implementations, where it accepts a second (or subsequent) broadcast fragments even when     sent in plaintext and then process them as full unfragmented frames. The highest threat from this     vulnerability is to integrity. (CVE-2020-26145)

    A flaw was found in ieee80211_rx_h_defragment in net/mac80211/rx.c in the Linux Kernel's WiFi     implementation. This vulnerability can be abused to inject packets or exfiltrate selected fragments when     another device sends fragmented frames, and the WEP, CCMP, or GCMP data-confidentiality protocol is used.
    The highest threat from this vulnerability is to integrity. (CVE-2020-26147)

    A flaw was found in the Linux kernel in certs/blacklist.c, When signature entries for EFI_CERT_X509_GUID     are contained in the Secure Boot Forbidden Signature Database, the entries are skipped. This can cause a     security threat and breach system integrity, confidentiality and even lead to a denial of service problem.
    (CVE-2020-26541)

    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)

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

    thermal/drivers/cpufreq_cooling: Fix slab OOB issue (CVE-2020-36776)

    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 flaw was found in the Linux kernel's KVM implementation, where improper handing of the VM_IO|VM_PFNMAP     VMAs in KVM bypasses RO checks and leads to pages being freed while still accessible by the VMM and guest.
    This flaw allows users who can start and control a VM to read/write random pages of memory, resulting in     local privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity,     and system availability. (CVE-2021-22543)

    Guest triggered use-after-free in Linux xen-netback A malicious or buggy network PV frontend can force     Linux netback to disable the interface and terminate the receive kernel thread associated with queue 0 in     response to the frontend sending a malformed packet. Such kernel thread termination will lead to a use-     after-free in Linux netback when the backend is destroyed, as the kernel thread associated with queue 0     will have already exited and thus the call to kthread_stop will be performed against a stale pointer.
    (CVE-2021-28691)

    An out-of-bounds access flaw was found in the Linux kernel's implementation of the eBPF code verifier,     where an incorrect register bounds calculation while checking unsigned 32-bit instructions in an eBPF     program occurs.. By default accessing the eBPF verifier is only accessible to privileged users with     CAP_SYS_ADMIN. The issue results from the lack of proper validation of user-supplied eBPF programs prior     to executing them. A local user could use this flaw to crash the system or possibly escalate their     privileges on the system. (CVE-2021-31440)

    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)

    The canbus filesystem in the Linux kernel contains an information leak of kernel memory to devices on the     CAN bus network link layer.  An attacker with the ability to dump messages on the CAN bus is able to learn     of uninitialized stack values by dumbing messages on the can bus. (CVE-2021-34693)

    The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size     was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel     and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee (bpf, ringbuf: Deny     reserve of buffers larger than ringbuf) (v5.13-rc4) and backported to the stable kernels in v5.12.4,     v5.11.21, and v5.10.37. It was introduced via 457f44363a88 (bpf: Implement BPF ring buffer and verifier     support for it) (v5.8-rc1). (CVE-2021-3489)

    The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly     update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and     therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e (bpf: Fix alu32 const     subreg bound tracking on bitwise operations) (v5.13-rc4) and backported to the stable kernels in v5.12.4,     v5.11.21, and v5.10.37. The AND/OR issues were introduced by commit 3f50f132d840 (bpf: Verifier, do     explicit ALU32 bounds tracking) (5.7-rc1) and the XOR variant was introduced by 2921c90d4718 (bpf:Fix a     verifier failure with xor) ( 5.10-rc1). (CVE-2021-3490)

    A flaw was found in the Linux kernel.  The io_uring PROVIDE_BUFFERS operation allowed the MAX_RW_COUNT     limit to be bypassed, which led to negative values being used in mem_rw when reading /proc/<PID>/mem. The     highest threat from this vulnerability is to data confidentiality and integrity as well as system     availability. (CVE-2021-3491)

    An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux     kernel. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a     system crash or a leak of internal kernel information. The highest threat from this vulnerability is to     system availability. (CVE-2021-3506)

    A flaw null pointer dereference in the Nitro Enclaves kernel driver was found in the way that Enclaves VMs     forces closures on the enclave file descriptor. A local user of a host machine could use this flaw to     crash the system or escalate their privileges on the system. (CVE-2021-3543)

    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)

    A flaw was found in the Linux kernels NFC implementation, A NULL pointer dereference and BUG leading to a     denial of service can be triggered by a local unprivileged user causing a kernel panic. (CVE-2021-38208)

    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:

    x86/kvm: Disable kvmclock on all CPUs on shutdown (CVE-2021-47110)

    In the Linux kernel, the following vulnerability has been resolved: net/tls: Fix use-after-free after the     TLS device goes down and up When a netdev with active TLS offload goes down, tls_device_down is called to     stop the offload and tear down the TLS context. However, the socket stays alive, and it still points to     the TLS context, which is now deallocated. 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.
