Synopsis
The remote OracleVM host is missing one or more security updates.Description
The remote OracleVM system is missing necessary patches to address security updates:- A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)
- A NULL pointer dereference vulnerability was found in netlink_dump. This issue can occur when the Netlink socket receives the message(sendmsg) for the XFRM_MSG_GETSA, XFRM_MSG_GETPOLICY type message, and the DUMP flag is set and can cause a denial of service or possibly another unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely. (CVE-2023-3106)
- A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This flaw allows an attacker with local user access to cause a system crash or leak internal kernel information. (CVE-2023-3567)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the affected kernel-uek / kernel-uek-firmware packages.See Also
