dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer.

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 5.10.82-83.359. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2024-049 advisory.

    A vulnerability was found in Linux kernel, where 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). (CVE-2020-27820)

    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)

    A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

    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. (CVE-2021-4001)

    A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

    A flaw heap buffer overflow in the Linux kernel's AMD Radeon graphics card driver was found in the way     user writes some malicious data to the AMD GPU Display Driver Debug Filesystem (to the VGA sub-directory     of the /sys/kernel/debug/ directory). A local user could use this flaw to crash the system or escalate     their privileges on the system. (CVE-2021-42327)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5362-1 advisory.

Tenable has extracted the preceding description block directly from the Ubuntu 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 remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5265-1 advisory.

    Jeremy Cline discovered a use-after-free in the nouveau graphics driver of the Linux kernel during device     removal. A privileged or physically proximate attacker could use this to cause a denial of service (system     crash). (CVE-2020-27820)

    It was discovered that the Bluetooth subsystem in the Linux kernel contained a use-after-free     vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2021-3640)

    Likang Luo discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel,     leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2021-3752)

    It was discovered that the SCTP protocol implementation in the Linux kernel did not properly verify VTAGs     in some situations. A remote attacker could possibly use this to cause a denial of service (connection     disassociation). (CVE-2021-3772)

    It was discovered that the eBPF implementation in the Linux kernel contained a race condition around read-     only maps. A privileged attacker could use this to modify read-only maps. (CVE-2021-4001)

    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)

    Felix Wilhelm discovered that the KVM implementation in the Linux kernel did not properly handle exit     events from AMD Secure Encrypted Virtualization-Encrypted State (SEV-ES) guest VMs. An attacker in a guest     VM could use this to cause a denial of service (host kernel crash) or possibly execute arbitrary code in     the host kernel. (CVE-2021-4093)

    Lin Ma discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel contained a     race condition, leading to a use-after-free vulnerability. A local attacker could use this to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-4202)

    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)

    Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel did not properly perform bounds     checking in some situations. A local attacker could use this to cause a denial of service (system crash)     or possibly execute arbitrary code. (CVE-2021-42739)

    It was discovered that the NFC subsystem in the Linux kernel contained a use-after-free vulnerability in     its NFC Controller Interface (NCI) implementation. A local attacker could possibly use this to cause a     denial of service (system crash) or execute arbitrary code. (CVE-2021-3760)

    It was discovered that the SCTP protocol implementation in the Linux kernel did not properly verify VTAGs     in some situations. A remote attacker could possibly use this to cause a denial of service (connection     disassociation). (CVE-2021-3772)

    It was discovered that the KVM implementation for POWER8 processors in the Linux kernel did not properly     keep track if a wakeup event could be resolved by a guest. An attacker in a guest VM could possibly use     this to cause a denial of service (host OS crash). (CVE-2021-43056)

    It was discovered that the TIPC Protocol implementation in the Linux kernel did not properly validate     MSG_CRYPTO messages in some situations. An attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2021-43267)

    It was discovered that the ISDN CAPI implementation in the Linux kernel contained a race condition in     certain situations that could trigger an array out-of-bounds bug. A privileged local attacker could     possibly use this to cause a denial of service or execute arbitrary code. (CVE-2021-43389)
