The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2022:0825 advisory.

  - 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)

  - A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's     cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting     the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.
    (CVE-2021-4154)

  - 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-2022-0330)

  - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends     a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have     access to the TIPC network. (CVE-2022-0435)

  - A vulnerability was found in the Linux kernel's 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.
    (CVE-2022-0492)

  - A vulnerability was found in kvm_s390_guest_sida_op in the arch/s390/kvm/kvm-s390.c function in KVM for     s390 in the Linux kernel. This flaw allows a local attacker with a normal user privilege to obtain     unauthorized memory write access. This flaw affects Linux kernel versions prior to 5.17-rc4.
    (CVE-2022-0516)

  - A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper     initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus     contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache     backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)

  - kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

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

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:0768-1 advisory.

  - In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered,     leading to a move_data_page NULL pointer dereference. (CVE-2021-44879)

  - Amazon Linux has been made aware of a potential Branch Target Injection (BTI) issue (sometimes referred to     as Spectre variant 2). This is a known cross-domain transient execution attack where a third party may     seek to cause a disclosure gadget to be speculatively executed after an indirect branch prediction.
    Generally, actors who attempt transient execution attacks do not have access to the data on the hosts they     attempt to access (e.g. where privilege-level isolation is in place). For such attacks to succeed, actors     need to be able to run code on the (virtual) machine hosting the data in which they are interested.
    (CVE-2022-0001, CVE-2022-0002, CVE-2022-0847)

  - A use-after-free vulnerability was found in rtsx_usb_ms_drv_remove in drivers/memstick/host/rtsx_usb_ms.c     in memstick in the Linux kernel. In this flaw, a local attacker with a user privilege may impact system     Confidentiality. This flaw affects kernel versions prior to 5.14 rc1. (CVE-2022-0487)

  - A vulnerability was found in the Linux kernel's 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.
    (CVE-2022-0492)

  - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

  - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the     O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a     regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file     descriptor. (CVE-2022-24448)

  - An issue was discovered in the Linux kernel before 5.16.5. There is a memory leak in yam_siocdevprivate in     drivers/net/hamradio/yam.c. (CVE-2022-24959)

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

    Jann Horn discovered a race condition in the Unix domain socket implementation in the Linux kernel that     could result in a read-after-free. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2021-4083)

    It was discovered that the NFS server implementation in the Linux kernel contained an out-of-bounds write     vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2021-4090)

    Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size     correctly when pre-allocating space in some situations. A local attacker could use this to expose     sensitive information. (CVE-2021-4155)

    It was discovered that the AMD Radeon GPU driver in the Linux kernel did not properly validate writes in     the debugfs file system. A privileged attacker could use this to cause a denial of service (system crash)     or possibly execute arbitrary code. (CVE-2021-42327)

    Sushma Venkatesh Reddy discovered that the Intel i915 graphics driver in the Linux kernel did not perform     a GPU TLB flush in some situations. A local attacker could use this to cause a denial of service or     possibly execute arbitrary code. (CVE-2022-0330)

    Samuel Page discovered that the Transparent Inter-Process Communication (TIPC) protocol implementation in     the Linux kernel contained a stack-based buffer overflow. A remote attacker could use this to cause a     denial of service (system crash) for systems that have a TIPC bearer configured. (CVE-2022-0435)

    It was discovered that the KVM implementation for s390 systems in the Linux kernel did not properly     prevent memory operations on PVM guests that were in non-protected mode. A local attacker could use this     to obtain unauthorized memory write access. (CVE-2022-0516)

    It was discovered that the ICMPv6 implementation in the Linux kernel did not properly deallocate memory in     certain situations. A remote attacker could possibly use this to cause a denial of service (memory     exhaustion). (CVE-2022-0742)

    It was discovered that the VMware Virtual GPU driver in the Linux kernel did not properly handle certain     failure conditions, leading to a stale entry in the file descriptor table.
