The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:0873-1 advisory.

  - An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer     arithmetic operations, the pointer modification performed by the first operation is not correctly     accounted for when restricting subsequent operations. (CVE-2021-29155)

  - An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to     cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h     lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.
    (CVE-2021-29650)

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