Description
A flaw was found in the Linux kernel's Orange File System (orangefs) client. The orangefs_prepare_cdm_array() function incorrectly calculates the buffer size for client debug keywords when an entry starts with a space. This can lead to a buffer overflow, allowing data to be written beyond the intended memory boundary. Such memory corruption could potentially result in a denial of service or other unspecified impacts.
