  - kernel: local privileges escalation in kernel/bpf/verifier.c (CVE-2022-23222)

  - Kernel: use-after-free in btf_dump_name_dups in tools/lib/bpf/btf_dump.c (CVE-2022-3534)

  - An issue was discovered in the Linux kernel through 5.2.13. nbd_genl_status in drivers/block/nbd.c does     not check the nla_nest_start_noflag return value. (CVE-2019-16089)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3642-1 advisory.

  - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because     the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads     to writing an arbitrary value. (CVE-2021-33033)

  - This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel     5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in     order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The     issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a     type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute     arbitrary code in the context of the kernel. Was ZDI-CAN-14689. (CVE-2021-34866)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on     inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - A flaw was found in the Linux kernel. A use-after-free vulnerability in the NFC stack can lead to a threat     to confidentiality, integrity, and system availability. (CVE-2021-3760)

  - 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)

  - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows     unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds     write. (CVE-2021-41864)

  - The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab     out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
    (CVE-2021-42008)

  - An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux     kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite     memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a     certain comparison uses values that are not memory sizes. (CVE-2021-42252)

  - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user     calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or     escalate privileges on the system. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-42739)

  - An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to     crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S     implementation bug in the handling of the SRR1 register values. (CVE-2021-43056)

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

  - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows     unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds     write. (CVE-2021-41864)

  - The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab     out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
    (CVE-2021-42008)

  - An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux     kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite     memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a     certain comparison uses values that are not memory sizes. (CVE-2021-42252)

  - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user     calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or     escalate privileges on the system. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-42739)

  - An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to     crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S     implementation bug in the handling of the SRR1 register values. (CVE-2021-43056)

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-2021:3641-1 advisory.

  - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because     the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads     to writing an arbitrary value. (CVE-2021-33033)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2021-42739. Reason: This candidate is a     reservation duplicate of CVE-2021-42739. Notes: All CVE users should reference CVE-2021-42739 instead of     this candidate. All references and descriptions in this candidate have been removed to prevent accidental     usage. (CVE-2021-3542)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on     inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - kernel: use-after-free in route4_change() in net/sched/cls_route.c (CVE-2021-3715)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2021-43389. Reason: This candidate is a     reservation duplicate of CVE-2021-43389. Notes: All CVE users should reference CVE-2021-43389 instead of     this candidate. All references and descriptions in this candidate have been removed to prevent accidental     usage. (CVE-2021-3896)

  - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel through 5.14.9 allows     unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds     write. (CVE-2021-41864)

  - The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab     out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
