Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.67%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
It was found that the "mknod" call derived from mknod(2) can create files pointing to devices on a glusterfs server node. An authenticated attacker could use this to create an arbitrary device and read data from any device attached to the glusterfs server node.
