Linux kernel get_fdb_entries() function integer overflow

linux-getfdbentries-integer-overflow (30588) The risk level is classified as HighHigh Risk

Description:

Linux kernel is vulnerable to an integer overflow within the get_fdb_entries() function in net/bridge/br_ioctl.c. By sending specially-crafted ioctl() requests, a local attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges.
