Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) NULL pointer dereference
EUVDB-ID: #VU80578
Risk: Low
CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-3772
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the xfrm_update_ae_params() function in the IP framework for transforming packets (XFRM subsystem). A local user with CAP_NET_ADMIN privileges can perform a denial of service (DoS) attack.
MitigationInstall updates from vendor's repository.
