Summary
The nvcoaft51 driver in Norman Virus Control (NVC) 5.82 uses weak permissions (unrestricted write access) for the NvcOa device, which allows local users to gain privileges by (1) triggering a buffer overflow in a kernel pool via a string argument to ioctl 0xBF67201C; or by (2) sending a crafted KEVENT structure through ioctl 0xBF672028 to overwrite arbitrary memory locations.
Exploit prediction (EPSS)
0.92% probability of exploitation in the next 30 days, higher than 61% of all scored CVEs.
