Improper locking in Linux kernel - CVE-2023-53109

Vulnerability identifier: #VU108480

CSH Severity: Low

CVSS v4: 6.8 [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]

CVE-ID: CVE-2023-53109

CWE-ID: CWE-667

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper locking within the LL_RESERVED_SPACE() function in net/ipv6/ip6_tunnel.c, within the ip_md_tunnel_xmit() and ip_tunnel_xmit() functions in net/ipv4/ip_tunnel.c. A local user can perform a denial of service (DoS) attack.
