The kernel-rt packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
On AMD64 systems, it was discovered that the kernel did not ensure the
ELF interpreter was available before making a call to the SET_PERSONALITY
macro. A local attacker could use this flaw to cause a denial of service by
running a 32-bit application that attempts to execute a 64-bit application.
(CVE-2010-0307, Moderate)
Information leak flaws were found in the Linux kernel Traffic Control
Unit implementation. A local attacker could use these flaws to cause the
kernel to leak kernel memory to user-space, possibly leading to the
disclosure of sensitive information. (CVE-2010-2942, Moderate)
It was found that wireless drivers might not always clear allocated
buffers when handling a driver-specific IOCTL information request. A local
user could trigger this flaw to cause kernel memory to leak from the heap
to user-space, leading to an information leak. (CVE-2010-2955, Moderate)
A flaw was found in the eql_g_master_cfg() function in the Linux kernel
equalizer load-balancer for serial network interfaces implementation. A
data structure in eql_g_master_cfg() was not initialized properly before
being copied to user-space. A local, unprivileged user could use this flaw
to cause an information leak. (CVE-2010-3297, Moderate)
Red Hat would like to thank Mathias Krause for reporting CVE-2010-0307, and
Dan Rosenberg for reporting CVE-2010-3297.
This update also fixes the following bugs:
No module dm-mem-cache found for kernel [version], aborting.
This was caused by an erroneous dependency on dmraid-related modules. This
update removes these dependencies with the result that mkinitrd does not
issue a spurious warning about the dm-mem-cache module not being found.
(BZ#482753)
The ibm_rtl kernel module now performs more exhaustive checking to ensure
it only loads on correct IBM hardware. (BZ#612275)
The realtime Linux kernel has been upgraded to upstream version
2.6.33.7-rt29, which provides a number of bug fixes and enhancements for
Red Hat Enterprise MRG 1.3. (BZ#638672)
Users should upgrade to these updated packages, which upgrade the kernel-rt
kernel to version 2.6.33.7-rt29 to correct these issues. The system must be
rebooted for this update to take effect.
