2) Resource management error
EUVDB-ID: #VU80121
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-3777
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper handling of table rules flush in certain circumstances within the netfilter subsystem in net/netfilter/nf_tables_api.c. A local user can perform a denial of service (DoS) attack or execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 27 for SLE 15 SP3) to the latest version.
