CVE-2010-4343
Published: 29 December 2010
drivers/scsi/bfa/bfa_core.c in the Linux kernel before 2.6.35 does not initialize a certain port data structure, which allows local users to cause a denial of service (system crash) via read operations on an fc_host statistics file.
From the Ubuntu Security Team
Krishna Gudipati discovered that the bfa adapter driver did not correctly initialize certain structures. A local attacker could read files in /sys to crash the system, leading to a denial of service.
