CVE-2023-26074
A heap-based buffer overflow in the 5G MM message codec can occur due to insufficient parameter validation when decoding operator-defined access category definitions.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.01%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
