Memory leak in Linux kernel - CVE-2023-53008

Vulnerability identifier: #VU106140

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-2023-53008

CWE-ID: CWE-401

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 memory leak within the SMB2_auth_kerberos() function in fs/cifs/smb2pdu.c, within the decode_ntlmssp_challenge() and sess_auth_kerberos() functions in fs/cifs/sess.c, within the build_avpair_blob() function in fs/cifs/cifsencrypt.c. A local user can perform a denial of service (DoS) attack.
