    - CVE-2022-0322: Fixed a denial of service in SCTP sctp_addto_chunk (bsc#1194985).
    - CVE-2021-44733: Fixed a use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux     kernel that occured because of a race condition in tee_shm_get_from_id during an attempt to free a shared     memory object (bnc#1193767).
    - CVE-2021-4197: Fixed a cgroup issue where lower privileged processes could write to fds of lower     privileged ones that could lead to privilege escalation (bsc#1194302).
    - CVE-2021-4135: Fixed an information leak in the nsim_bpf_map_alloc function (bsc#1193927).
    - CVE-2021-4202: Fixed a race condition during NFC device remove which could lead to a use-after-free     memory corruption (bsc#1194529)
    - CVE-2021-4083: A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix     domain socket file handlers in the way users call close() and fget() simultaneously and can potentially     trigger a race condition. This flaw allowed a local user to crash the system or escalate their privileges     on the system. (bnc#1193727).
    - CVE-2021-4149: Fixed a locking condition in btrfs which could lead to system deadlocks (bsc#1194001).
    - CVE-2021-45485: The IPv6 implementation in net/ipv6/output_core.c had an information leak because of     certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can     typically choose among many IPv6 source addresses (bnc#1194094).
    - CVE-2021-45486: The IPv4 implementation in net/ipv4/route.c had an information leak because the hash     table is very small (bnc#1194087).
    - CVE-2021-4001: A race condition was found in the Linux kernel's ebpf verifier between     bpf_map_update_elem and bpf_map_freeze due to a missing lock in kernel/bpf/syscall.c. In this flaw, a     local user with a special privilege (cap_sys_admin or cap_bpf) can modify the frozen mapped address space.
    (bnc#1192990).
    - CVE-2021-28715: Guest can force Linux netback driver to hog large amounts of kernel memory. 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 was 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: Guest can force Linux netback driver to hog large amounts of kernel memory.

    - CVE-2021-28713: Rogue backends can cause DoS of guests via high frequency events. 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. (bsc#1193440)

    - CVE-2020-27825: A use-after-free flaw was found in kernel/trace/ring_buffer.c. There was a race problem     in trace_open and resize of cpu buffer running parallely on different cpus, may cause a denial of service     problem (DOS). This flaw could even allow a local attacker with special user privilege to a kernel     information leak threat (bnc#1179960).
    - CVE-2021-43975: hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c     allowed an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted     length value (bnc#1192845).
    - CVE-2021-33098: Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version     3.17.3 may have allowed an authenticated user to potentially enable denial of service via local access     (bnc#1192877).
    - CVE-2021-43976: mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allowed an attacker (who     can connect a crafted USB device) to cause a denial of service (skb_over_panic) (bnc#1192847).
    - CVE-2021-4002: Incorrect TLBs flushing after huge_pmd_unshare could lead to exposing hugepages to other     users (bsc#1192946).
    - CVE-2020-27820: 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)     (bnc#1179599).

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 5.4.95-42.163. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-020 advisory.

    A use-after-free flaw was found in kernel/trace/ring_buffer.c in Linux kernel. There was a race problem in     trace_open and resize of cpu buffer running parallely on different cpus, may cause a denial of service     problem (DOS). This flaw could even allow a local attacker with special user  privilege to a kernel     information leak threat. (CVE-2020-27825)

    A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an     attacker with a local account to leak information about kernel internal addresses. The highest threat from     this vulnerability is to confidentiality. (CVE-2021-20239)

    A flaw leak of the file handle for parent directory in the Linux kernel's NFS3 functionality was found in     the way user calls READDIRPLUS. A local user could use this flaw to traverse to other parts of the file-     system than mounted sub-folder. (CVE-2021-3178)

    A flaw was found in the Linux kernel. A use-after-free memory flaw in the Fast Userspace Mutexes     functionality allowing a local user to crash the system or escalate their privileges on the system. The     highest threat from this vulnerability is to data confidentiality and integrity as well as system     availability. (CVE-2021-3347)

    A use after free flaw in the Linux kernel network block device (NBD) subsystem was found in the way user     calls an ioctl NBD_SET_SOCK at a certain point during device setup. (CVE-2021-3348)

    A remote denial of service vulnerability was found in the Linux kernel's TIPC kernel module. The while     loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue.
    Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system     to instantly spike to 100%, causing a denial of service condition. (CVE-2023-1390)

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

  - A use-after-free flaw was found in kernel/trace/ring_buffer.c in Linux kernel (before 5.10-rc1). There was     a race problem in trace_open and resize of cpu buffer running parallely on different cpus, may cause a     denial of service problem (DOS). This flaw could even allow a local attacker with special user privilege     to a kernel information leak threat. (CVE-2020-27825)

Note that Nessus relies on the presence of the package as reported by the vendor.
