A flaw was found in the Linux kernel's implementation of Logical Link Control and Adaptation Protocol (L2CAP), part of the Bluetooth stack. An attacker, within the range of standard Bluetooth transmissions, can create and send a specially crafted packet. The response to this specially crafted packet can contain part of the kernel stack which can be used in a further attack.

A flaw was found in the Linux kernel's implementation of logical link control and adaptation protocol (L2CAP), part of the Bluetooth stack in the l2capparseconfrsp and l2capparseconfreq functions. An attacker with physical access within the range of standard Bluetooth transmission can create a specially crafted packet. The response to this specially crafted packet can contain part of the kernel stack which can be used in a further attack.

A flaw was found in the implementation of Intel Transactional Synchronization Extensions (TSX) abortion where a local authenticated attacker with the ability to monitor execution time is able to infer TSX memory state by comparing abort execution times.

This could allow information disclosure via this observed sidechannel for any TSX transaction being executed while an attacker is able to observe abort timing.

A flaw was found in pfnswapentrytopage in memory management subsystem in the Linux Kernel. In this flaw, an attacker with a local user privilege may cause a denial of service problem due to a BUG statement referencing pmdt x.
