TITLE

Linux Foundation of yocto Out-of-Bounds Write Vulnerability in Other Vendors' Products

Trust: 0.8

sources: JVNDB: JVNDB-2022-018866

DESCRIPTION

In cpu dvfs, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07139405; Issue ID: ALPS07139405. Linux Foundation of yocto Products from other vendors have out-of-bounds write vulnerabilities.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. MediaTek Inc. is the world's fourth-largest foundry semiconductor company. It is in a leading position in the markets of mobile terminals, smart home applications, wireless connection technology and Internet of Things products, with approximately 1.5 billion units a year End products with built-in MediaTek chips are available all over the world. Many MediaTek chips have a privilege escalation vulnerability. This vulnerability is due to the lack of boundary checks in cpu dvfs, which leads to out-of-bounds writes
