Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU75807
Risk: Low
CVSSv3.1: 7.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2023-32233
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in Netfilter nf_tables when processing batch requests. A local user can trigger a use-after-free error and execute arbitrary code with root privileges.
Install update from vendor's website.
