Vulnerability from fkie_nvd - Published: 2021-08-23 13:15 - Updated: 2024-11-21 06:12
Summary
Certain Arm products before 2021-08-23 do not properly consider the effect of exceptions on a VLLDM instruction. A Non-secure handler may have read or write access to part of a Secure context. This affects Arm Cortex-M33 r0p0 through r1p0, Arm Cortex-M35P r0, Arm Cortex-M55 r0p0 through r1p0, and Arm China STAR-MC1 (in the STAR SE configuration).
