Actively Exploited
CISA Known Exploited Vulnerabilities (KEV) Catalog
EPSS (Exploit Prediction Scoring System) estimates a 3.2% chance this CVE is exploited in the wild within the next 30 days — higher than 88% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.
Linux kernel fb_mmap function in drivers/video/fbmem.c contains an integer overflow vulnerability that allows for privilege escalation.
Description
Integer overflow in the fb_mmap function in drivers/video/fbmem.c in the Linux kernel before 3.8.9, as used in a certain Motorola build of Android 4.1.2 and other products, allows local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted /dev/graphics/fb0 mmap2 system calls, as demonstrated by the Motochopper pwn program.
