Uncontrolled resource consumption in the Linux kernel drivers for Intel(R) SGX may allow an authenticated user to potentially enable denial of service via local access.

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

  - Uncontrolled resource consumption in the Linux kernel drivers for Intel(R) SGX may allow an authenticated     user to potentially enable denial of service via local access. (CVE-2021-33135)

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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3288-1 advisory.

  - The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to     simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI     error injection through EINJ when securelevel is set. (CVE-2016-3695)

  - 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)

  - Uncontrolled resource consumption in the Linux kernel drivers for Intel(R) SGX may allow an authenticated     user to potentially enable denial of service via local access. (CVE-2021-33135)

  - A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that     allows local users to create files for the XFS file-system with an unintended group ownership and with     group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a member of this group. This can lead to excessive     permissions granted in case when they should not. This vulnerability is similar to the previous     CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)

  - 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)

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

  - In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input     validation. 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-223375145References: Upstream kernel (CVE-2022-20369)

  - kernel: posix cpu timer use-after-free may lead to local privilege escalation (CVE-2022-2585)

  - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation     (CVE-2022-2588)

  - 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)

  - 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)

  - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

  - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)

  - A flaw was found in hw. Mis-trained branch predictions for return instructions may allow arbitrary     speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-23816)     (CVE-2022-28693)

  - An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller     driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input     data. This flaw allows a local user to crash the system. (CVE-2022-2873)

  - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the     bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to     gain unauthorized access to data. (CVE-2022-2905)

  - 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)

  - A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring().
    The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper     locking when performing operations on an object. This flaw allows a local user to crash the system or     escalate their privileges on the system. (CVE-2022-2959)

  - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where     virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-     free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)

  - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

  - An issue was discovered in the Linux kernel through 5.16-rc6. There is a lack of check after calling     vzalloc() and lack of free after allocation in drivers/media/test-drivers/vidtv/vidtv_s302m.c.
    (CVE-2022-3078)

  - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

  - 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)

  - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

  - An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of     service can occur upon binding to an already bound chain. (CVE-2022-39190)

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