11) Resource management error

EUVDB-ID: #VU89397

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-26640

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

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

The vulnerability exists due to improper management of internal resources within the skb_advance_to_frag() function in net/ipv4/tcp.c. A remote attacker can send specially crafted data to the system and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
