Description
This security bulletin contains information about 1 security vulnerability.
1) Memory corruption (CVE-ID: CVE-2018-7550)
The vulnerability allows an adjacent attacker to execute arbitrary code on the target system.The weakness exists in the load_multiboot function due to out-of-bounds read or write. An adjacent attacker can load a kernel image during the boot process, which may cause the mh_load_end_addr address to be greater than the mh_bss_end_addr address, trigger memory corruption and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
