Description Mark J. Cox 2004-06-16 07:12:37 EDT

Recently committed to the 2.6 kernel were enhancements from Al Viro
that enabled the Sparse source code checking tool to check for a
certain class kernel bugs. This class of bugs can lead to privilege
escalation vulnerabilities.  Some of these fixes also apply to the 2.4
kernel and have been backported.  Specifically affecting the RHEL kernels:

1. Direct write to a user-supplied address which can lead to privilege
escalation in the decnet, mpu401, and pss drivers.

2. Direct read of a user-supplied address can cause information leak
from kernel memory in the airo, asus_acpi, mpu401, and pss drivers.

3. Deadlock in the msnd driver.Direct write to a user-supplied address
which can lead to privilege escalation in the decnet, mpu401, and pss
drivers.

Direct read of a user-supplied address can cause information leak from
kernel memory in the airo, asus_acpi, mpu401, and pss drivers.

Deadlock in the msnd driver.

Errata in progress.

Comment 2 Mark J. Cox 2004-06-16 08:46:16 EDT

(Note the decnet, mpu401, pss, and msnd drivers are classed as
unsupported in RHEL3)
