CVE-2026-33901
In versions below both 7.1.2-19 and 6.9.13-44, a heap buffer overflow occurs in the MVG decoder that could result in an out of bounds write when processing a crafted image.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
