Missing release of memory after effective lifetime in Linux kernel

1) Missing release of memory after effective lifetime

EUVDB-ID: #VU99726

Risk: Low

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2005-3848

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

Memory leak in the icmp_push_reply function in Linux 2.6 before 2.6.12.6 and 2.6.13 allows remote attackers to cause a denial of service (memory consumption) via a large number of crafted packets that cause the ip_append_data function to fail, aka 'DST leak in icmp_push_reply.'

Mitigation

Install update from vendor's repository.
