CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of inline ECC carveouts in the DBSC5 DRAM controller on arm64 systems, where improper reservation of memory areas can lead to corruption during high DRAM utilization. This can result in system instability, posing a risk to data integrity and overall system performance. Organizations utilizing Linux on arm64 hardware with the DBSC5 DRAM controller should prioritize addressing this issue to maintain system reliability.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: arm64: dts: renesas: ironhide: Describe inline ECC carveouts The DBSC5 DRAM controller protects DRAM content using inline ECC. The inline ECC utilizes areas of DRAM for its operation, which are in the DRAM address range, but must not be accessed or modified. Describe the inline ECC carveout areas used by the DBSC5 controller on this hardware as reserved-memory, which must not be accessed. Include DRAM areas which are unprotected by ECC as well, those are parts of the DRAM which directly precede the ECC carveout. In case of high DRAM utilization, unless the inline ECC carveouts are properly reserved, Linux may use and corrupt the memory used by the DBSC5 DRAM controller for inline ECC, which would lead to the system becoming unstable.
