CVE-2021-41289

Status: ModifiedHigh (7.1)—

ASUS P453UJ contains the Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability. With a general user’s permission, local attackers can modify the BIOS by replacing or filling in the content of the designated Memory DataBuffer, which causing a failure of integrity verification and further resulting in a failure to boot.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
