CVE-2023-38432

Published: 18 July 2023

An issue was discovered in the Linux kernel before 6.3.10. fs/smb/server/smb2misc.c in ksmbd does not validate the relationship between the command payload size and the RFC1002 length specification, leading to an out-of-bounds read.

From the Ubuntu Security Team

Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel did not properly validate command payload size, leading to a out-of-bounds read vulnerability. A remote attacker could possibly use this to cause a denial of service (system crash).

Notes

AuthorNote
rodrigo-zaiden
needs ksmbd-tools installed to enable the service, which is
not installed by default.
