Dan Rosenberg discovered that multiple terminal ioctls did not correctly initialize structure memory. A local attacker could exploit this to read portions of kernel stack memory, leading to a loss of privacy. (CVE-2010-4076, CVE-2010-4077)
Alex Shi and Eric Dumazet discovered that the network stack did not correctly handle packet backlogs. A remote attacker could exploit this by sending a large amount of network traffic to cause the system to run out of memory, leading to a denial of service. (CVE-2010-4251, CVE-2010-4805)
It was discovered that the /proc filesystem did not correctly handle permission changes when programs executed. A local attacker could hold open files to examine details about programs running with higher privileges, potentially increasing the chances of exploiting additional vulnerabilities. (CVE-2011-1020)
Dan Rosenberg discovered that the X.25 Rose network stack did not correctly handle certain fields. If a system was running with Rose enabled, a remote attacker could send specially crafted traffic to gain root privileges. (CVE-2011-1493)
Timo Warns discovered that the GUID partition parsing routines did not correctly validate certain structures. A local attacker with physical access could plug in a specially crafted block device to crash the system, leading to a denial of service. (CVE-2011-1577)
It was discovered that CIFS incorrectly handled authentication. When a user had a CIFS share mounted that required authentication, a local user could mount the same share without knowing the correct password.
(CVE-2011-1585)
It was discovered that the GRE protocol incorrectly handled netns initialization. A remote attacker could send a packet while the ip_gre module was loading, and crash the system, leading to a denial of service. (CVE-2011-1767)
It was discovered that the IP/IP protocol incorrectly handled netns initialization. A remote attacker could send a packet while the ipip module was loading, and crash the system, leading to a denial of service. (CVE-2011-1768)
Ben Hutchings reported a flaw in the kernel’s handling of corrupt LDM partitions. A local user could exploit this to cause a denial of service or escalate privileges. (CVE-2011-2182)
Andrea Righi discovered a race condition in the KSM memory merging support. If KSM was being used, a local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-2183)
Dan Rosenberg discovered that the IPv4 diagnostic routines did not correctly validate certain requests. A local attacker could exploit this to consume CPU resources, leading to a denial of service.
(CVE-2011-2213)
Vasiliy Kulikov discovered that taskstats listeners were not correctly handled. A local attacker could exploit this to exhaust memory and CPU resources, leading to a denial of service. (CVE-2011-2484)
It was discovered that Bluetooth l2cap and rfcomm did not correctly initialize structures. A local attacker could exploit this to read portions of the kernel stack, leading to a loss of privacy.
(CVE-2011-2492)
Mauro Carvalho Chehab discovered that the si4713 radio driver did not correctly check the length of memory copies. If this hardware was available, a local attacker could exploit this to crash the system or gain root privileges. (CVE-2011-2700)
Herbert Xu discovered that certain fields were incorrectly handled when Generic Receive Offload (CVE-2011-2723)
Vasiliy Kulikov discovered that the Comedi driver did not correctly clear memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2011-2909)
The performance counter subsystem did not correctly handle certain counters. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-2918)
A flaw was found in the Linux kernel’s /proc/*/map interface. A local, unprivileged user could exploit this flaw to cause a denial of service. (CVE-2011-3637)
Ben Hutchings discovered several flaws in the Linux Rose (X.25 PLP) layer. A local user or a remote user on an X.25 network could exploit these flaws to execute arbitrary code as root. (CVE-2011-4914).
