"The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2022:1037-1 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)

  - In ufshcd_eh_device_reset_handler of ufshcd.c, there is a possible out of bounds read due to a missing
    bounds check. This could lead to local information disclosure with System execution privileges needed.
    User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-194696049References: Upstream kernel (CVE-2021-39657)

  - 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)

  - 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 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)

  - drivers/usb/gadget/legacy/inode.c in the Linux kernel through 5.16.8 mishandles dev->buf release.
    (CVE-2022-24958)

  - 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)

  - An issue was discovered in drivers/usb/gadget/composite.c in the Linux kernel before 5.16.10. The USB
    Gadget subsystem lacks certain validation of interface OS descriptor requests (ones with a large array
    index and ones associated with NULL function pointer retrieval). Memory corruption might occur.
    (CVE-2022-25258)

  - net/netfilter/nf_dup_netdev.c in the Linux kernel 5.4 through 5.6.10 allows local users to gain privileges
    because of a heap out-of-bounds write. This is related to nf_tables_offload. (CVE-2022-25636)

  - st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has
    EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)

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