In the Linux kernel, the following vulnerability has been resolved: mptcp: clear 'kern' flag from fallback sockets The mptcp ULP extension relies on sk->sk_sock_kern being set correctly: It prevents setsockopt(fd, IPPROTO_TCP, TCP_ULP, "mptcp", 6); from working for plain tcp sockets (any userspace-exposed socket). But in case of fallback, accept() can return a plain tcp sk. In such case, sk is still tagged as 'kernel' and setsockopt will work. This will crash the kernel, The subflow extension has a NULL ctx->conn mptcp socket: BUG: KASAN: null-ptr-deref in subflow_data_ready+0x181/0x2b0 Call Trace: tcp_data_ready+0xf8/0x370 [..]

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

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 5.10.93-87.444. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-009 advisory.

    A denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was     found in the way users call some interrupts with high frequency from one of the guests.A local user could     use this flaw to starve the resources resulting in a denial of service. (CVE-2021-28711)

(CVE-2021-28713)

    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: 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)

    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)

    A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

    A flaw memory leak in the Linux kernel's eBPF for the Simulated networking device driver in the way user     uses BPF for the device such that function nsim_map_alloc_elem being called. A local user could use this     flaw to get unauthorized access to some data. (CVE-2021-4135)

    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)

    An out-of-bounds write flaw was found in the Linux kernel's Aquantia AQtion Ethernet card Atlantic driver     in the way the ethernet card provides malicious input to the driver. This flaw allows a local user to     emulate the networking device and crash the system. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2021-43975)

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

    sctp: use call_rcu to free endpoint (CVE-2021-46929)

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

    net/mlx5e: Wrap the tx reporter dump callback to extract the sq (CVE-2021-46931)

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

    i2c: validate user data in compat ioctl

    Wrong user data may cause warning in i2c_transfer(), ex: zero msgs.Userspace should not be able to trigger     warnings, so this patch addsvalidation checks for user data in compact ioctl to prevent reportedwarnings     (CVE-2021-46934)

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

    net: fix use-after-free in tw_timer_handler (CVE-2021-46936)

    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-2022-0185)
