CVE-2018-19523

Status: ModifiedMedium (5.5)—

DriverAgent 2.2015.7.14, which includes DrvAgent64.sys 1.0.0.1, allows a user to send an IOCTL (0x80002068) with a user defined buffer size. If the size of the buffer is less than 512 bytes, then the driver will overwrite the next pool header if there is one next to the user buffer's pool.

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).
