Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Resource management error
EUVDB-ID: #VU66550
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-36879
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the xfrm_expand_policies() function in net/xfrm/xfrm_policy.c. A local user can cause the refcount to be dropped twice and perform a denial of service (DoS) attack.
MitigationInstall updates from vendor's repository.
