The version of kernel-generic installed on the remote host is prior to 5.15.27 / 5.15.27_smp. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2022-067-01 advisory.

  • 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 vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

  • 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)

  • An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive information from kernel memory. (CVE-2022-25375)

  • 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)

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