  - In the Linux kernel, the following vulnerability has been resolved: fscache: Fix oops due to race with     cookie_lru and use_cookie If a cookie expires from the LRU and the LRU_DISCARD flag is set, but the state     machine has not run yet, it's possible another thread can call fscache_use_cookie and begin to use it.
    When the cookie_worker finally runs, it will see the LRU_DISCARD flag set, transition the cookie->state to     LRU_DISCARDING, which will then withdraw the cookie. Once the cookie is withdrawn the object is removed     the below oops will occur because the object associated with the cookie is now NULL. Fix the oops by     clearing the LRU_DISCARD bit if another thread uses the cookie before the cookie_worker runs. BUG: kernel     NULL pointer dereference, address: 0000000000000008 ...

  - In the Linux kernel, the following vulnerability has been resolved: scsi: aacraid: Fix double-free on     probe failure aac_probe_one() calls hardware-specific init functions through the aac_driver_ident::init     pointer, all of which eventually call down to aac_init_adapter(). If aac_init_adapter() fails after     allocating memory for aac_dev::queues, it frees the memory but does not clear that member. After the     hardware-specific init function returns an error, aac_probe_one() goes down an error path that frees the     memory pointed to by aac_dev::queues, resulting.in a double-free.

  - In the Linux kernel, the following vulnerability has been resolved: uprobes: fix kernel info leak via     [uprobes] vma xol_add_vma() maps the uninitialized page allocated by __create_xol_area() into userspace.
    On some architectures (x86) this memory is readable even without VM_READ, VM_EXEC results in the same     pgprot_t as VM_EXEC|VM_READ, although this doesn't really matter, debugger can read this memory anyway.
