Tenable has extracted the preceding description block directly from the Oracle Linux 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 SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2615-1 advisory.

  - Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result     in data leakage. (CVE-2021-26341)

  - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an     authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)

  - An out-of-bounds (OOB) memory access flaw was found in the Linux kernel's eBPF due to an Improper Input     Validation. This flaw allows a local attacker with a special privilege to crash the system or leak     internal information. (CVE-2021-4204)

  - 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)

  - The check_alu_op() function in kernel/bpf/verifier.c in the Linux kernel through v5.16-rc5 did not     properly update bounds while handling the mov32 instruction, which allows local users to obtain     potentially sensitive address information, aka a pointer leak. (CVE-2021-45402)

  - A vulnerability was found in the Linux kernel's eBPF verifier when handling internal data structures.
    Internal memory locations could be returned to userspace. A local attacker with the permissions to insert     eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit     mitigations in place for the kernel. This flaws affects kernel versions < v5.16-rc6 (CVE-2022-0264)

(CVE-2022-29901)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

  - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data     Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further     processing to nevertheless be freed. (CVE-2022-33743)

  - drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of     a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.
    (CVE-2022-33981)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init     (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different     vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an     unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data     in net/netfilter/nf_tables_api.c. (CVE-2022-34918)
