Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Type Confusion
EUVDB-ID: #VU65360
Risk: Low
CVSSv4.0: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear]
CVE-ID: CVE-2022-34918
CWE-ID:
CWE-843 - Type confusion
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists in the Linux kernel’s Netfilter subsystem in the way a user provides incorrect input of the NFT_DATA_VERDICT type. A local user can pass specially crafted data to the application, trigger a type confusion error and escalate privileges on the system.
MitigationInstall updates from vendor's repository.

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
Yes. This vulnerability is being exploited in the wild.
2) Use-after-free
EUVDB-ID: #VU64668
Risk: Low
CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-32250
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 incorrect NFT_STATEFUL_EXPR in net/netfilter/nf_tables_api.c in Linux kernel. A local user with ability to create user/net namespaces can execute arbitrary code with root privileges.
