CVE-2006-5751
Integer overflow in the get_fdb_entries function in net/bridge/br_ioctl.c in the Linux kernel before 2.6.18.4 allows local users to execute arbitrary code via a large maxnum value in an ioctl request.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
