Description

A flaw was found in the Linux kernel's hp-bioscfg component. The hp_get_string_from_buffer() function contains an off-by-one write vulnerability. This occurs because the NUL terminator can be written one byte beyond the allocated buffer, leading to a buffer overflow. An attacker could potentially exploit this to cause memory corruption.
