| In the Linux kernel, the following vulnerability has been resolved:
wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi()
The simple_write_to_buffer() function will succeed if even a single
byte is initialized. However, we need to initialize the whole buffer
to prevent information leaks. Just use memdup_user(). |
| In the Linux kernel, the following vulnerability has been resolved:
tools/power turbostat: Fix file pointer leak
Currently if a fscanf fails then an early return leaks an open
file pointer. Fix this by fclosing the file before the return.
Detected using static analysis with cppcheck:
tools/power/x86/turbostat/turbostat.c:2039:3: error: Resource leak: fp [resourceLeak] |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix the assign logic of iocb
commit 18ae8d12991b ("f2fs: show more DIO information in tracepoint")
introduces iocb field in 'f2fs_direct_IO_enter' trace event
And it only assigns the pointer and later it accesses its field
in trace print log.

| In the Linux kernel, the following vulnerability has been resolved:
xhci: Remove device endpoints from bandwidth list when freeing the device
Endpoints are normally deleted from the bandwidth list when they are
dropped, before the virt device is freed.
If xHC host is dying or being removed then the endpoints aren't dropped
cleanly due to functions returning early to avoid interacting with a
non-accessible host controller.
So check and delete endpoints that are still on the bandwidth list when
freeing the virt device.
Solves a list_del corruption kernel crash when unbinding xhci-pci,
caused by xhci_mem_cleanup() when it later tried to delete already freed
endpoints from the bandwidth list.
This only affects hosts that use software bandwidth checking, which
currenty is only the xHC in intel Panther Point PCH (Ivy Bridge) |
| In the Linux kernel, the following vulnerability has been resolved:
xen/gntdev: Accommodate VMA splitting
Prior to this commit, the gntdev driver code did not handle the
following scenario correctly with paravirtualized (PV) Xen domains:
* User process sets up a gntdev mapping composed of two grant mappings
(i.e., two pages shared by another Xen domain).
* User process munmap()s one of the pages.
* User process munmap()s the remaining page.
* User process exits.
In the scenario above, the user process would cause the kernel to log
the following messages in dmesg for the first munmap(), and the second
munmap() call would result in similar log messages:
BUG: Bad page map in process doublemap.test pte:... pmd:...

For each munmap() call, the Xen hypervisor (if built with CONFIG_DEBUG)
would print out the following and trigger a general protection fault in
the affected Xen PV domain:
(XEN) d0v... Attempt to implicitly unmap d0's grant PTE ...
(XEN) d0v... Attempt to implicitly unmap d0's grant PTE ...
As of this writing, gntdev_grant_map structure's vma field (referred to
as map->vma below) is mainly used for checking the start and end
addresses of mappings. However, with split VMAs, these may change, and
there could be more than one VMA associated with a gntdev mapping.
Hence, remove the use of map->vma and rely on map->pages_vm_start for
the original start address and on (map->count << PAGE_SHIFT) for the
original mapping size. Let the invalidate() and find_special_page()
hooks use these.
Also, given that there can be multiple VMAs associated with a gntdev
mapping, move the "mmu_interval_notifier_remove(&map->notifier)" call to
the end of gntdev_put_map, so that the MMU notifier is only removed
after the closing of the last remaining VMA.
Finally, use an atomic to prevent inadvertent gntdev mapping re-use,
instead of using the map->live_grants atomic counter and/or the map->vma
pointer (the latter of which is now removed). This prevents the
userspace from mmap()'ing (with MAP_FIXED) a gntdev mapping over the
same address range as a previously set up gntdev mapping. This scenario
can be summarized with the following call-trace, which was valid prior
to this commit:
mmap
gntdev_mmap
mmap (repeat mmap with MAP_FIXED over the same address range)
gntdev_invalidate
unmap_grant_pages (sets 'being_removed' entries to true)
gnttab_unmap_refs_async
unmap_single_vma
gntdev_mmap (maps the shared pages again)
munmap
gntdev_invalidate
unmap_grant_pages
(no-op because 'being_removed' entries are true)
unmap_single_vma (For PV domains, Xen reports that a granted page
is being unmapped and triggers a general protection fault in the
affected domain, if Xen was built with CONFIG_DEBUG)
The fix for this last scenario could be worth its own commit, but we
opted for a single commit, because removing the gntdev_grant_map
structure's vma field requires guarding the entry to gntdev_mmap(), and
the live_grants atomic counter is not sufficient on its own to prevent
the mmap() over a pre-existing mapping. |

| In the Linux kernel, the following vulnerability has been resolved:
ntb_netdev: Use dev_kfree_skb_any() in interrupt context
TX/RX callback handlers (ntb_netdev_tx_handler(),
ntb_netdev_rx_handler()) can be called in interrupt
context via the DMA framework when the respective
DMA operations have completed. As such, any calls
by these routines to free skb's, should use the
interrupt context safe dev_kfree_skb_any() function.
Previously, these callback handlers would call the
interrupt unsafe version of dev_kfree_skb(). This has
not presented an issue on Intel IOAT DMA engines as
that driver utilizes tasklets rather than a hard
interrupt handler, like the AMD PTDMA DMA driver.
On AMD systems, a kernel WARNING message is
encountered, which is being issued from
skb_release_head_state() due to in_hardirq()
being true.
Besides the user visible WARNING from the kernel,
the other symptom of this bug was that TCP/IP performance
across the ntb_netdev interface was very poor, i.e.
approximately an order of magnitude below what was
expected. With the repair to use dev_kfree_skb_any(),
kernel WARNINGs from skb_release_head_state() ceased
and TCP/IP performance, as measured by iperf, was on
par with expected results, approximately 20 Gb/s on
AMD Milan based server. Note that this performance
is comparable with Intel based servers. |
