The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0198-1 advisory.

  - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

  - A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device     driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called. A     local user could use this flaw to get unauthorized access to some data. (CVE-2021-4135)

  - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an     improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of     service (DOS) due to a deadlock problem. (CVE-2021-4149)

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

  - A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in     the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem     while the device is getting removed, leading to a privilege escalation problem. (CVE-2021-4202)

  - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information     leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based     attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)

  - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak     because the hash table is very small. (CVE-2021-45486)

  - nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to     cause a denial of service (NULL pointer dereference and general protection fault) because of the missing     initialization for nft_set_elem_expr_alloc. A local user can set a netfilter table expression in their own     namespace. (CVE-2021-46283)

  - A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem     Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in     case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local     user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to     legacy handling) could use this flaw to escalate their privileges on the system. (CVE-2022-0185)

  - A flaw was found in the sctp_make_strreset_req function in net/sctp/sm_make_chunk.c in the SCTP network     protocol in the Linux kernel with a local user privilege access. In this flaw, an attempt to use more     buffer than is allocated triggers a BUG_ON issue, leading to a denial of service (DOS). (CVE-2022-0322)

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