The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2022:7683 advisory.

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer     dereference and general protection fault. (CVE-2020-36558)

  - A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the     way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()     together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A     privileged local user could use this flaw to crash the system or escalate their privileges on the system.
    (CVE-2021-3640)

  - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
    (CVE-2021-30002)

  - A denial of service (DOS) issue was found in the Linux kernel's smb2_ioctl_query_info function in the     fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user     function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.
    (CVE-2022-0168)

  - 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)

  - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.
    This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)

  - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a     use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel     information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

  - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers     concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM     for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the     system. (CVE-2022-1048)

  - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain     privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past     commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)

  - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

  - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of     service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal     instruction in guest in the Intel CPU. (CVE-2022-1852)

  - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an     attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and     possibly to run code. (CVE-2022-2078)

  - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

  - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is     disabled by default, it could allow an attacker to crash the system or have other memory-corruption side     effects. (CVE-2022-2938)

  - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel     (CVE-2022-20368)

  - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.
    An attacker with access to a serial port could trigger the debugger so it is important that the debugger     respect the lockdown mode when/if it is triggered. (CVE-2022-21499)

  - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation,     aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to     influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive     information. (CVE-2022-23960)

  - 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)

  - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow     an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)

  - In drivers/hid/hid-elo.c in the Linux kernel before 5.16.11, a memory leak exists for a certain hid_parse     error condition. (CVE-2022-27950)

  - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.
    (CVE-2022-28390)

  - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets     are in the intended state. (CVE-2022-28893)

  - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

  - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote     attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte     nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)

  - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation     (CVE-2022-2586)

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

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

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2022:7444 advisory.

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer     dereference and general protection fault. (CVE-2020-36558)

  - A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the     way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()     together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A     privileged local user could use this flaw to crash the system or escalate their privileges on the system.
    (CVE-2021-3640)

  - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
    (CVE-2021-30002)

  - A denial of service (DOS) issue was found in the Linux kernel's smb2_ioctl_query_info function in the     fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user     function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.
    (CVE-2022-0168)

  - 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)

  - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.
    This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)

  - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a     use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel     information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

  - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers     concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM     for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the     system. (CVE-2022-1048)

  - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain     privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past     commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)

  - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

  - A NULL pointer dereference flaw was found in the Linux kernel's KVM module, which can lead to a denial of     service in the x86_emulate_insn in arch/x86/kvm/emulate.c. This flaw occurs while executing an illegal     instruction in guest in the Intel CPU. (CVE-2022-1852)

  - A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an     attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and     possibly to run code. (CVE-2022-2078)

  - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

  - A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is     disabled by default, it could allow an attacker to crash the system or have other memory-corruption side     effects. (CVE-2022-2938)

  - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel     (CVE-2022-20368)

  - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.
    An attacker with access to a serial port could trigger the debugger so it is important that the debugger     respect the lockdown mode when/if it is triggered. (CVE-2022-21499)

  - 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)

  - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow     an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)

  - In drivers/hid/hid-elo.c in the Linux kernel before 5.16.11, a memory leak exists for a certain hid_parse     error condition. (CVE-2022-27950)

  - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.
    (CVE-2022-28390)

  - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets     are in the intended state. (CVE-2022-28893)

  - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

  - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote     attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte     nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)

  - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation     (CVE-2022-2586)
