Vulnerability description
DayBreach CVE AI Research
CVE-2021-42252 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison uses values that are not memory sizes.
