  - A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root     (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD     CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)

  - In binder_inc_ref_for_node of binder.c, there is a possible way to corrupt memory due to a use after free.
    This could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-239630375References: Upstream kernel (CVE-2022-20421)

  - A flaw was found in vDPA with VDUSE backend. There are currently no checks in VDUSE kernel driver to     ensure the size of the device config space is in line with the features advertised by the VDUSE userspace     application. In case of a mismatch, Virtio drivers config read helpers do not initialize the memory     indirectly passed to vduse_vdpa_get_config() returning uninitialized memory from the stack. This could     cause undefined behavior or data leaks in Virtio drivers. (CVE-2022-2308)

  - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

  - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the     bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to     gain unauthorized access to data. (CVE-2022-2905)

  - A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function     security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use     this flaw to crash the system or potentially escalate their privileges on the system. (CVE-2022-2978)

  - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

  - Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver     through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by     zero error. (CVE-2022-3061)

  - A flaw was found in the Linux kernel. A denial of service flaw may occur if there is a consecutive request     of the NVME_IOCTL_RESET and the NVME_IOCTL_SUBSYS_RESET through the device file of the driver, resulting     in a PCIe link disconnect. (CVE-2022-3169)

  - There exists a use-after-free in io_uring in the Linux kernel. Signalfd_poll() and binder_poll() use a     waitqueue whose lifetime is the current task.

A remote attacker could execute code leaking kernel memory via Bluetooth if within     proximity of the victim. We recommend upgrading past commit https://www.google.com/url     https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4     https://www.google.com/url (CVE-2022-42896)

  - drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-     space client to corrupt the monitor's internal memory. (CVE-2022-43750)

  - The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer     overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send     buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer     to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC     message with garbage data is still correctly formed according to the specification and is passed forward     to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the     allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (CVE-2022-43945)

  - A flaw was found in hw. Mis-trained branch predictions for return instructions may allow arbitrary     speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-23816)     (CVE-2022-2602)

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3450-1 advisory.

  - The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to     simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI     error injection through EINJ when securelevel is set. (CVE-2016-3695)

  - A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl()     printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had     been freed by gprinter_free(). (CVE-2020-27784)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size     increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS     filesystem otherwise not accessible to them. (CVE-2021-4155)

  - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and     SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a     user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)

  - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the     small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of     service problem. (CVE-2022-1012)

  - In various methods of kernel base drivers, there is a possible out of bounds write due to a heap buffer     overflow. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:

  - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

  - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

  - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the     bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to     gain unauthorized access to data. (CVE-2022-2905)

  - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

  - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where     virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-     free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)

  - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously.

(CVE-2022-3028)

  - net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free. (CVE-2022-32250)

  - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

  - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

  - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to     restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently     allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass     verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and     unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for     peripherals that do not verify firmware updates. We recommend upgrading past commit     4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)
