CentOS Errata and Security Advisory CESA-2015:0164
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Red Hat would like to thank Akira Fujita of NEC for reporting this issue.
This update also fixes the following bugs:
Previously, hot-unplugging of a virtio-blk device could in some cases
lead to a kernel panic, for example during in-flight I/O requests.
This update fixes race condition in the hot-unplug code in the
virtio_blk.ko module. As a result, hot unplugging of the virtio-blk device
no longer causes the guest kernel oops when there are in-flight I/O
requests. (BZ#1006536)
Before this update, due to a bug in the error-handling path, a corrupted
metadata block could be used as a valid block. With this update, the error
handling path has been fixed and more checks have been added to verify the
metadata block. Now, when a corrupted metadata block is encountered, it is
properly marked as corrupted and handled accordingly. (BZ#1034403)
Previously, an incorrectly initialized variable resulted in a random
value being stored in the variable that holds the number of default ACLs,
and is sent in the SET_PATH_INFO data structure. Consequently, the setfacl
command could, under certain circumstances, fail with an “Invalid argument”
error. With this update, the variable is correctly initialized to zero,
thus fixing the bug. (BZ#1105625)
All kernel users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The system must be
rebooted for this update to take effect.
