Security Bulletin
This security bulletin contains one low risk vulnerability.
EUVDB-ID: #VU95766
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2005-2099
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to perform service disruption.
The Linux kernel before 2.6.12.5 does not properly destroy a keyring that is not instantiated properly, which allows local users or remote attackers to cause a denial of service (kernel oops) via a keyring with a payload that is not empty, which causes the creation to fail, leading to a null dereference in the keyring destructor.
MitigationInstall update from vendor's repository.
Vulnerable software versionsLinux kernel: All versions
