The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2022:0029 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2022-0330:
    A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the     way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or     escalate their privileges on the system.

    CVE-2022-22942:
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.

    CVE-2021-4197:
    An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system.

    CVE-2022-0185:
    A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem     Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in     case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local     user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to     legacy handling) could use this flaw to escalate their privileges on the system.

    CVE-2022-0492:
    A vulnerability was found in the Linux kernels cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0367-1 advisory.

  - The BPF subsystem in the Linux kernel before 4.17 mishandles situations with a long jump over an     instruction sequence where inner instructions require substantial expansions into multiple BPF     instructions, leading to an overflow. This affects kernel/bpf/core.c and net/core/filter.c.
    (CVE-2018-25020)

  - An issue was discovered on Broadcom Wi-Fi client devices. Specifically timed and handcrafted traffic can     cause internal errors (related to state transitions) in a WLAN device that lead to improper layer 2 Wi-Fi     encryption with a consequent possibility of information disclosure over the air for a discrete set of     traffic, a different vulnerability than CVE-2019-9500, CVE-2019-9501, CVE-2019-9502, and CVE-2019-9503.
    (CVE-2019-15126)

  - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver). (CVE-2020-27820)

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. 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: A-196926917References:
    Upstream kernel (CVE-2021-0920)

  - In ip6_xmit of ip6_output.c, there is a possible out of bounds write due to a use after free. 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: A-168607263References:

  - Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the     ability to run PV backends in regular unprivileged guests, typically referred to as driver domains.
    Running PV backends in driver domains has one primary security advantage: if a driver domain gets     compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain     could try to attack other guests via sending events at a high frequency leading to a Denial of Service in     the guest due to trying to service interrupts for elongated amounts of time. There are three affected     backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch     3, CVE-2021-28713 (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713)

  - Guest can force Linux netback driver to hog large amounts of kernel memory T[his CNA information record     relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]     Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715) The timeout could even never trigger if the guest manages to have only one free slot in     its RX queue ring page and the next package would require more than one free slot, which may be the case     when using GSO, XDP, or software hashing. (CVE-2021-28714) (CVE-2021-28714, CVE-2021-28715)

This flaw could allow a local attacker with user privileges to cause a data race problem     while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)

  - In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in     drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a     crafted device) to trigger an out-of-bounds write via a crafted length value. (CVE-2021-43975)

  - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows     an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).
    (CVE-2021-43976)

  - A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.

CVE-2022-1729     Norbert Slusarek discovered a race condition in the perf subsystem which could result in local privilege     escalation to root. The default settings in Debian prevent exploitation unless more permissive settings     have been applied in the kernel.perf_event_paranoid sysctl. CVE-2022-1734 Duoming Zhou discovered race     conditions in the nfcmrvl NFC driver that could lead to a use-after-free, double-free or null pointer     dereference. A local user might be able to exploit these for denial of service (crash or memory     corruption) or possibly for privilege escalation. This driver is not enabled in Debian's official kernel     configurations. CVE-2022-1974, CVE-2022-1975 Duoming Zhou discovered that the NFC netlink interface was     suspectible to denial of service. CVE-2022-2153 kangel reported a flaw in the KVM implementation for x86     processors which could lead to a null pointer dereference. A local user permitted to access /dev/kvm could     exploit this to cause a denial of service (crash). CVE-2022-21123, CVE-2022-21125, CVE-2022-21166 Various     researchers discovered flaws in Intel x86 processors, collectively referred to as MMIO Stale Data     vulnerabilities. These are similar to the previously published Microarchitectural Data Sampling (MDS)     issues and could be exploited by local users to leak sensitive information. For some CPUs, the mitigations     for these issues require updated microcode. An updated intel-microcode package may be provided at a later     date. The updated CPU microcode may also be available as part of a system firmware (BIOS) update.
    Further information on the mitigation can be found at https://www.kernel.org/doc/html/latest/admin-     guide/hw-vuln/processor_mmio_stale_data.html or in the linux-doc-4.19 package. CVE-2022-23960 Researchers     at VUSec discovered that the Branch History Buffer in Arm processors can be exploited to create     information side channels with speculative execution. This issue is similar to Spectre variant 2, but     requires additional mitigations on some processors. This was previously mitigated for 32-bit Arm (armel     and armhf) architectures and is now also mitigated for 64-bit Arm (arm64). This can be exploited to obtain     sensitive information from a different security context, such as from user-space to the kernel, or from a     KVM guest to the kernel. CVE-2022-26490 Buffer overflows in the STMicroelectronics ST21NFCA core driver     can result in denial of service or privilege escalation. This driver is not enabled in Debian's official     kernel configurations. CVE-2022-27666 valis reported a possible buffer overflow in the IPsec ESP     transformation code. A local user can take advantage of this flaw to cause a denial of service or for     privilege escalation. CVE-2022-28356 Beraphin discovered that the ANSI/IEEE 802.2 LLC type 2 driver did     not properly perform reference counting on some error paths. A local attacker can take advantage of this     flaw to cause a denial of service. CVE-2022-28388 A double free vulnerability was discovered in the 8     devices USB2CAN interface driver. CVE-2022-28389 A double free vulnerability was discovered in the     Microchip CAN BUS Analyzer interface driver. CVE-2022-28390 A double free vulnerability was discovered in     the EMS CPC-USB/ARM7 CAN/USB interface driver. CVE-2022-29581 Kyle Zeng discovered a reference-counting     bug in the cls_u32 network classifier which can lead to a use-after-free. A local user can exploit this to     cause a denial of service (crash or memory corruption) or possibly for privilege escalation.
    CVE-2022-30594 Jann Horn discovered a flaw in the interaction between ptrace and seccomp subsystems. A     process sandboxed using seccomp() but still permitted to use ptrace() could exploit this to remove the     seccomp restrictions. CVE-2022-32250 Aaron Adams discovered a use-after-free in Netfilter which may result     in local privilege escalation to root. CVE-2022-33981 Yuan Ming from Tsinghua University reported a race     condition in the floppy driver involving use of the FDRAWCMD ioctl, which could lead to a use-after-free.
    A local user with access to a floppy drive device could exploit this to cause a denial of service (crash     or memory corruption) or possibly for privilege escalation. This ioctl is now disabled by default. For the     oldstable distribution (buster), these problems have been fixed in version 4.19.249-2. Due to an issue in     the signing service (Cf. Debian bug #1012741), the vport-vxlan module cannot be loaded for the signed     kernel for amd64 in this update. This update also corrects a regression in the network scheduler subsystem     (bug #1013299). For the 32-bit Arm (armel and armhf) architectures, this update enables optimised     implementations of several cryptographic and CRC algorithms. For at least AES, this should remove a timing     sidechannel that could lead to a leak of sensitive information. This update includes many more bug fixes     from stable updates 4.19.236-4.19.249 inclusive, including for bug #1006346. The random driver has been     backported from Linux 5.19, fixing numerous performance and correctness issues. Some changes will be     visible: The entropy pool size is now 256 bits instead of 4096. You may need to adjust the configuration     of system monitoring or user-space entropy gathering services to allow for this. On systems without a     hardware RNG, the kernel may log more uses of /dev/urandom before it is fully initialised. These uses were     previously under-counted and this is not a regression. We recommend that you upgrade your linux packages.
