In the Linux kernel, the following vulnerability has been resolved: net: validate lwtstate->data before returning from skb_tunnel_info() skb_tunnel_info() returns pointer of lwtstate->data as ip_tunnel_info type without validation. lwtstate->data can have various types such as mpls_iptunnel_encap, etc and these are not compatible. So skb_tunnel_info() should validate before returning that pointer.

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: synproxy: Fix out of bounds     when parsing TCP options The TCP option parser in synproxy (synproxy_parse_options) could read one byte     out of bounds. When the length is 1, the execution flow gets into the loop, reads one byte of the opcode,     and if the opcode is neither TCPOPT_EOL nor TCPOPT_NOP, it reads one more byte, which exceeds the length     of 1. This fix is inspired by commit 9609dad263f8 (ipv4: tcp_input: fix stack out of bounds when parsing     TCP options.). v2 changes: Added an early return when length < 0 to avoid calling skb_header_pointer with     negative length. (CVE-2021-47245)

  - In the Linux kernel, the following vulnerability has been resolved: drm: Fix use-after-free read in     drm_getunique() There is a time-of-check-to-time-of-use error in drm_getunique() due to retrieving     file_priv->master prior to locking the device's master mutex. An example can be seen in the crash report     of the use-after-free error found by Syzbot:
    https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803 In the report, the master     pointer was used after being freed. This is because another process had acquired the device's master mutex     in drm_setmaster_ioctl(), then overwrote fpriv->master in drm_new_set_master(). The old value of     fpriv->master was subsequently freed before the mutex was unlocked. To fix this, we lock the device's     master mutex before retrieving the pointer from from fpriv->master. This patch passes the Syzbot     reproducer test. (CVE-2021-47280)

  - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)

  - In the Linux kernel, the following vulnerability has been resolved: media: ngene: Fix out-of-bounds bug in     ngene_command_config_free_buf() Fix an 11-year old bug in ngene_command_config_free_buf() while addressing     the following warnings caught with -Warray-bounds: arch/alpha/include/asm/string.h:22:16: warning:
    '__builtin_memcpy' offset [12, 16] from the object at 'com' is out of the bounds of referenced subobject     'config' with type 'unsigned char' at offset 10 [-Warray-bounds] arch/x86/include/asm/string_32.h:182:25:
    warning: '__builtin_memcpy' offset [12, 16] from the object at 'com' is out of the bounds of referenced     subobject 'config' with type 'unsigned char' at offset 10 [-Warray-bounds] The problem is that the     original code is trying to copy 6 bytes of data into a one-byte size member _config_ of the wrong structue     FW_CONFIGURE_BUFFERS, in a single call to memcpy(). This causes a legitimate compiler warning because     memcpy() overruns the length of &com.cmd.ConfigureBuffers.config. It seems that the right structure is     FW_CONFIGURE_FREE_BUFFERS, instead, because it contains 6 more members apart from the header _hdr_. Also,     the name of the function ngene_command_config_free_buf() suggests that the actual intention is to     ConfigureFreeBuffers, instead of ConfigureBuffers (which takes place in the function     ngene_command_config_buf(), above). Fix this by enclosing those 6 members of struct     FW_CONFIGURE_FREE_BUFFERS into new struct config, and use &com.cmd.ConfigureFreeBuffers.config as the     destination address, instead of &com.cmd.ConfigureBuffers.config, when calling memcpy(). This also helps     with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the     FORTIFY_SOURCE routines on memcpy(). (CVE-2021-47288)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-988891 advisory.

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

    net: validate lwtstate->data before returning from skb_tunnel_info()

    skb_tunnel_info() returns pointer of lwtstate->data as ip_tunnel_info     type without validation. lwtstate->data can have various types such as     mpls_iptunnel_encap, etc and these are not compatible.
    So skb_tunnel_info() should validate before returning that pointer.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 5.10.59-52.142. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-004 advisory.

    A flaw was found in the Linux kernel, where a BPF program can obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel attack. This issue occurs when the protection mechanism     neglects the possibility of uninitialized memory locations on the BPF stack. The highest threat from this     vulnerability is to confidentiality. (CVE-2021-34556)

    A flaw in the Linux kernel allows a privileged BPF program to obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel in the eBPF subsystem (CVE-2021-35477)

    A vulnerability was found in the Linux kernel. Missing size validations on inbound SCTP packets may allow     the kernel to read uninitialized memory. (CVE-2021-3655)

    A lack of CPU resources in the Linux kernel tracing module functionality was found in the way users use     the trace ring buffer in specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could     use this flaw to starve the resources causing denial of service. (CVE-2021-3679)

    A flaw use-after-free in the Linux kernel USB High Speed Mobile Devices functionality was found in the way     user detaches USB device. A local user could use this flaw to crash the system or escalate their     privileges on the system. (CVE-2021-37159)

    ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

    A flaw was found in the hanging of mounts in the Linux kernel's NFS4 subsystem where remote servers are     unreachable for the client during migration of data from one server to another (during trunking     detection). This flaw allows a remote NFS4 server (if the client is connected) to starve the resources,     causing a denial of service. The highest threat from this vulnerability is to system availability.

The version of kernel installed on the remote host is prior to 5.4.141-67.229. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-006 advisory.

    A flaw was found in the Linux kernel. This flaw allows attackers to cause a denial of service (soft     lockup) by triggering the destruction of a large SEV VM, which requires unregistering many encrypted     regions. The highest threat from this vulnerability is to system availability. (CVE-2020-36311)

    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 in the Linux kernel allows a privileged BPF program to obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel in the eBPF subsystem (CVE-2021-35477)

    A vulnerability was found in the Linux kernel. Missing size validations on inbound SCTP packets may allow     the kernel to read uninitialized memory. (CVE-2021-3655)

    A lack of CPU resources in the Linux kernel tracing module functionality was found in the way users use     the trace ring buffer in specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could     use this flaw to starve the resources causing denial of service. (CVE-2021-3679)

    ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

    A flaw was found in the Linux kernel, where it incorrectly computes the access permissions of a shadow     page. This issue leads to a missing guest protection page fault. (CVE-2021-38198)

    A flaw was found in the hanging of mounts in the Linux kernel's NFS4 subsystem where remote servers are     unreachable for the client during migration of data from one server to another (during trunking     detection). This flaw allows a remote NFS4 server (if the client is connected) to starve the resources,     causing a denial of service. The highest threat from this vulnerability is to system availability.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 4.14.248-129.473. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2021-1539 advisory.

    A flaw was found in the Linux kernel. When reusing a socket with an attached dccps_hc_tx_ccid as a     listener, the socket will be used after being released leading to denial of service (DoS) or a potential     code execution. The highest threat from this vulnerability is to data confidentiality and integrity as     well as system availability. (CVE-2020-16119)

    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)

    A flaw in the Linux kernel allows a privileged BPF program to obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel in the eBPF subsystem (CVE-2021-35477)

    A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse     a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. (CVE-2021-3609)

    A vulnerability was found in the Linux kernel. Missing size validations on inbound SCTP packets may allow     the kernel to read uninitialized memory. (CVE-2021-3655)

    A lack of CPU resources in the Linux kernel tracing module functionality was found in the way users use     the trace ring buffer in specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could     use this flaw to starve the resources causing denial of service. (CVE-2021-3679)

    A flaw was found in the Linux kernel's OverlayFS subsystem in the way the user mounts the TmpFS filesystem     with OverlayFS. This flaw allows a local user to gain access to hidden files that should not be     accessible. (CVE-2021-3732)

    A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may     cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl     (KDSETMDE). The highest threat from this vulnerability is to data confidentiality. (CVE-2021-3753)

    A flaw was found on the Linux kernel. On the PowerPC platform, the KVM guest allows the OS users to cause     host OS memory corruption via rtas_args.nargs. The highest threat from this vulnerability is to data     confidentiality and integrity as well as system availability. (CVE-2021-37576)

    ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:

    A flaw was found in the Linux kernel. A denial of service attack (use-after-free and panic) can be caused     by a physically proximate attack by removing a MAX-3421 USB device in certain situations. The highest     threat from this vulnerability is to data confidentiality and integrity as well as system availability.
    (CVE-2021-38204)

    A flaw was found in the Linux kernel that allows attackers to defeat an ASLR protection mechanism because     it prints a kernel pointer (i.e., the real IOMEM pointer). The highest threat from this vulnerability is     to confidentiality. (CVE-2021-38205)

    A flaw was found in the Linux kernel. A race condition was discovered in the ext4 subsystem. The highest     threat from this vulnerability is to data confidentiality and integrity as well as system availability.
    (CVE-2021-40490)

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

    net: validate lwtstate->data before returning from skb_tunnel_info() (CVE-2021-47309)

    In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead     to local escalation of privilege when opening and closing inet sockets with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)
