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.

Affected products

Linux kernel: 2.4.0-test1, 2.4.0-test10, 2.4.0-test11, 2.4.0-test12, 2.4.0-test2, 2.4.0-test3 (+48)
