The ext4_fill_super function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly validate meta block groups, which allows physically proximate attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image.

Exploit prediction (EPSS)

0.43% probability of exploitation in the next 30 days, higher than 37% of all scored CVEs.
