Descriptions

In the Linux kernel, the following vulnerability has been resolved: btrfs: don't BUG_ON() when 0 reference count at btrfs_lookup_extent_info() Instead of doing a BUG_ON() handle the error by returning -EUCLEAN,
aborting the transaction and logging an error message.

Michael Randrianantenaina discovered that the Bluetooth driver in the Linux Kernel contained an improper access control vulnerability. A nearby attacker could use this to connect a rogue device and possibly execute arbitrary code. It was discovered that the CIFS network file system implementation in the Linux kernel did not properly verify the target namespace when handling upcalls. An attacker could use this to expose sensitive information.
