CVE-2004-2607 Information

Description

A numeric casting discrepancy in sdla_xfer in Linux kernel 2.6.x up to 2.6.5 and 2.4 up to 2.4.29-rc1 allows local users to read portions of kernel memory via a large len argument which is received as an int but cast to a short which prevents a read loop from filling a buffer.
