Input validation error in Linux kernel - CVE-2023-52636

Published: July 11, 2024 / Updated: May 13, 2025


Vulnerability identifier: #VU94138
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-2023-52636
CWE-ID: CWE-20
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

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

The vulnerability exists due to improper input validation within the get_reply() and prep_next_sparse_read() functions in net/ceph/osd_client.c, within the decrypt_tail() and prepare_read_tail_plain() functions in net/ceph/messenger_v2.c, within the sizeof_footer(), read_partial_sparse_msg_data() and read_partial_message() functions in net/ceph/messenger_v1.c. A local user can perform a denial of service (DoS) attack.
