Subject: diag: Improve handling of IOCTLs
|
||||||
|
|
||||||
|
DIAG kernel driver interacts with user space processes using
|
||||||
|
IOCTLS. This change adds conditions to avoid potential integer
|
||||||
|
over/underflow, incorrect buffer copy.

Subject: diag: Improve handling of IOCTLs
|
||||||
|
|
||||||
|
DIAG kernel driver interacts with user space processes using
|
||||||
|
IOCTLS. This change adds conditions to avoid potential integer
|
||||||
|
over/underflow, incorrect buffer copy.

Subject: msm: kgsl: Detect and avoid malformed ioctl codes
|
||||||
|
|
||||||
|
Because we were using _IO_NR, one could construct a malformed ioctl
|
||||||
|
code that would avoid allocating memory yet go to a function that
|
||||||
|
expected that memory. Still use _IO_NR to index the array of ioctls,
|
||||||
|
but check that the full values match before jumping to the helper
|
||||||
|
function.

||||||

snd_compr_allocate_buffer()
|
|

|

These are 32 bit values that come from the user, we need to check for

|

integer overflows or we could end up allocating a smaller buffer than
|
|

expected.

Subject: msm:camera: Fix overflow issue in ioctl_hw_cmds function
|
||||||
|
|
||||||
|
'len' is of type signed int 32bit,but the assigned value
|
||||||
|
may exceed maximum unsigned int32 range.Add overflow check
|
||||||
|
and graceful exit if 'm'exceeds UINT32_MAX value.

Subject: msm: Make CONFIG_STRICT_MEMORY_RWX even stricter
|
||||||
|
|
||||||
|
If CONFIG_STRICT_MEMORY_RWX was set, the first section (containing
|
||||||
|
the kernel page table and the initial code) and the section
|
||||||
|
containing the init code were both given RWX permission, which is
|
||||||
|
a potential security hole.
|
||||||
|
|
||||||
|
Pad the first section after the initial code (which will never
|
||||||
|
be executed when the MMU is on) to make the rest of the kernel
|
||||||
|
text start in the second section and make the first section RW.
|
||||||
|
|
||||||
|
Move some data which had ended up in the "init text"
|
||||||
|
section into the "init data" one, as this is RW, not RX.
|
||||||
|
Make the "init text" RX.
|
||||||
|
|
||||||
|
We will not free the section containing the "init text",
|
||||||
|
because if we do, the kernel will allocate memory for RW data there.

Subject: ARM: 7527/1: uaccess: explicitly check __user pointer when
|
||||||
|
!CPU_USE_DOMAINS
|
||||||
|
|
||||||
|
The {get,put}_user macros don't perform range checking on the provided
|
||||||
|
__user address when !CPU_HAS_DOMAINS.
|
||||||
|
|
||||||
|
This patch reworks the out-of-line assembly accessors to check the user
|
||||||
|
address against a specified limit, returning -EFAULT if is is out of
|
||||||
|
range.
|
||||||
|
|
||||||
|
[will: changed get_user register allocation to match put_user]
|
||||||

Subject: unix: avoid use-after-free in ep_remove_wait_queue
|
||||||
|
|
||||||
|
Rainer Weikusat <rweikusat@mobileactivedefense.com> writes:
|
||||||
|
An AF_UNIX datagram socket being the client in an n:1 association with
|
||||||
|
some server socket is only allowed to send messages to the server if the
|
||||||
|
receive queue of this socket contains at most sk_max_ack_backlog
|
||||||
|
datagrams. This implies that prospective writers might be forced to go
|
||||||
|
to sleep despite none of the message presently enqueued on the server
|
||||||
|
receive queue were sent by them. In order to ensure that these will be
|
||||||
|
woken up once space becomes again available, the present unix_dgram_poll
|
||||||
|
routine does a second sock_poll_wait call with the peer_wait wait queue
|
||||||
|
of the server socket as queue argument (unix_dgram_recvmsg does a wake
|
||||||
|
up on this queue after a datagram was received). This is inherently
|
||||||
|
problematic because the server socket is only guaranteed to remain alive
|
||||||
|
for as long as the client still holds a reference to it. In case the
|
||||||
|
connection is dissolved via connect or by the dead peer detection logic
|
||||||
|
in unix_dgram_sendmsg, the server socket may be freed despite "the
|
||||||
|
polling mechanism" (in particular, epoll) still has a pointer to the
|
||||||
|
corresponding peer_wait queue. There's no way to forcibly deregister a
|
||||||
|
wait queue with epoll.
|
||||||
|
|
||||||
|
Based on an idea by Jason Baron, the patch below changes the code such
|
||||||
|
that a wait_queue_t belonging to the client socket is enqueued on the
|
||||||
|
peer_wait queue of the server whenever the peer receive queue full
|
||||||
|
condition is detected by either a sendmsg or a poll. A wake up on the
|
||||||
|
peer queue is then relayed to the ordinary wait queue of the client
|
||||||
|
socket via wake function. The connection to the peer wait queue is again
|
||||||
|
dissolved if either a wake up is about to be relayed or the client
|
||||||
|
socket reconnects or a dead peer is detected or the client socket is
|
||||||
|
itself closed. This enables removing the second sock_poll_wait from
|
||||||
|
unix_dgram_poll, thus avoiding the use-after-free, while still ensuring
|
||||||
|
that no blocked writer sleeps forever.

Subject: msm: kgsl: Protect CP_STATE_DEBUG_INDEX
|
||||||
|
|
||||||
|
Put CP_STATE_DEBUG_INDEX and CP_STATE_DEBUG_DATA under protection
|
||||||
|
to keep it from being written from an IB1. Doing so however opens
|
||||||
|
up a subtle "feature" in the microcode: memory read opcodes turn off
|
||||||
|
protected mode in the microcode to do the read and then turns it
|
||||||
|
back on regardless of the initial state. This is a problem if the
|
||||||
|
memory read happens while protected mode is turned off and then we
|
||||||
|
try to access a protected register which then complains and goes boom.
|
||||||
|
|
||||||
|
To account for this irregularity explicitly turn back off protected
|
||||||
|
mode in all the places where we know this will be a problem.

||||||

Subject: filter: prevent nla extensions to peek beyond the end of the message
|
|
||||||
|
|
||||||
[ Upstream commit 05ab8f2647e4221cbdb3856dd7d32bd5407316b3 ]
|
|
||||||
|
|
||||||
The BPF_S_ANC_NLATTR and BPF_S_ANC_NLATTR_NEST extensions fail to check
|
|
||||||
for a minimal message length before testing the supplied offset to be
|
|
||||||
within the bounds of the message. This allows the subtraction of the nla
|
|
||||||
header to underflow and therefore -- as the data type is unsigned --
|
|
||||||
allowing far to big offset and length values for the search of the
|
|
||||||
netlink attribute.
|
|
||||||
|
|
||||||
The remainder calculation for the BPF_S_ANC_NLATTR_NEST extension is
|
|
||||||
also wrong. It has the minuend and subtrahend mixed up, therefore
|
|
||||||
calculates a huge length value, allowing to overrun the end of the
|
|
||||||
message while looking for the netlink attribute.
|
|
||||||
|
|
||||||
The following three BPF snippets will trigger the bugs when attached to
|
|
||||||
a UNIX datagram socket and parsing a message with length 1, 2 or 3.

||||||

||||||

Fix the first issue by ensuring the message length fulfills the minimal
|
|
||||||
size constrains of a nla header. Fix the second bug by getting the math
|
|
||||||
for the remainder calculation right.

Subject: qseecom: Add boundary checks for offset within message.
|
||||||
|
|
||||||
|
Qseecom driver does not have boundary checks for offset within the
|
||||||
|
message. So this patch add checks to validate the offsets sent by
|
||||||
|
client to modify data within the command request message and it
|
||||||
|
should not exceed the memory allocated for that message.

|
||||||
|
inputs.

Subject: ALSA: control: Fix replacing user controls
|
|
||||||
|
|
||||||
commit 82262a46627bebb0febcc26664746c25cef08563 upstream.
|
|
||||||
|
|
||||||
There are two issues with the current implementation for replacing user
|
|
||||||
controls. The first is that the code does not check if the control is actually a
|
|
||||||
user control and neither does it check if the control is owned by the process
|
|
||||||
that tries to remove it. That allows userspace applications to remove arbitrary
|
|
||||||
controls, which can cause a user after free if a for example a driver does not
|
|
||||||
expect a control to be removed from under its feed.
|
|
||||||
|
|
||||||
The second issue is that on one hand when a control is replaced the
|
|
||||||
user_ctl_count limit is not checked and on the other hand the user_ctl_count is
|
|
||||||
increased (even though the number of user controls does not change). This allows
|
|
||||||
userspace, once the user_ctl_count limit as been reached, to repeatedly replace
|
|
||||||
a control until user_ctl_count overflows. Once that happens new controls can be
|
|
||||||
added effectively bypassing the user_ctl_count limit.
|
|
||||||
|
|
||||||
Both issues can be fixed by instead of open-coding the removal of the control
|
|
||||||
that is to be replaced to use snd_ctl_remove_user_ctl(). This function does
|
|
||||||
proper permission checks as well as decrements user_ctl_count after the control
|
|
||||||
has been removed.
|
|
||||||
|
|
||||||
Note that by using snd_ctl_remove_user_ctl() the check which returns -EBUSY at
|
|
||||||
beginning of the function if the control already exists is removed. This is not
|
|
||||||
a problem though since the check is quite useless, because the lock that is
|
|
||||||
protecting the control list is released between the check and before adding the
|
|
||||||
new control to the list, which means that it is possible that a different
|
|
||||||
control with the same settings is added to the list after the check. Luckily
|
|
||||||
there is another check that is done while holding the lock in snd_ctl_add(), so
|
|
||||||
we'll rely on that to make sure that the same control is not added twice.

Subject: ALSA: control: Make sure that id->index does not overflow
|
|
||||||
|
|
||||||
commit 883a1d49f0d77d30012f114b2e19fc141beb3e8e upstream.
|
|
||||||
|
|
||||||
The ALSA control code expects that the range of assigned indices to a control is
|
|
||||||
continuous and does not overflow. Currently there are no checks to enforce this.
|
|
||||||
If a control with a overflowing index range is created that control becomes
|
|
||||||
effectively inaccessible and unremovable since snd_ctl_find_id() will not be
|
|
||||||
able to find it. This patch adds a check that makes sure that controls with a
|
|
||||||
overflowing index range can not be created.

Subject: mac80211: fix fragmentation code, particularly for encryption
|
|
||||||
|
|
||||||
commit 338f977f4eb441e69bb9a46eaa0ac715c931a67f upstream.
|
|
||||||
|
|
||||||
The "new" fragmentation code (since my rewrite almost 5 years ago)
|
|
||||||
erroneously sets skb->len rather than using skb_trim() to adjust
|
|
||||||
the length of the first fragment after copying out all the others.
|
|
||||||
This leaves the skb tail pointer pointing to after where the data
|
|
||||||
originally ended, and thus causes the encryption MIC to be written
|
|
||||||
at that point, rather than where it belongs: immediately after the
|
|
||||||
data.
|
|
||||||
|
|
||||||
The impact of this is that if software encryption is done, then
|
|
||||||
a) encryption doesn't work for the first fragment, the connection
|
|
||||||
becomes unusable as the first fragment will never be properly
|
|
||||||
verified at the receiver, the MIC is practically guaranteed to
|
|
||||||
be wrong
|
|
||||||
b) we leak up to 8 bytes of plaintext (!) of the packet out into
|
|
||||||
the air
|
|
||||||
|
|
||||||
This is only mitigated by the fact that many devices are capable
|
|
||||||
of doing encryption in hardware, in which case this can't happen
|
|
||||||
as the tail pointer is irrelevant in that case. Additionally,
|
|
||||||
fragmentation is not used very frequently and would normally have
|
|
||||||
to be configured manually.
|
|
||||||
|
|
||||||
Fix this by using skb_trim() properly.

Subject: isofs: Fix infinite looping over CE entries
|

commit f54e18f1b831c92f6512d2eedb224cd63d607d3d upstream.
|
|
||||||
|
|
||||||
Rock Ridge extensions define so called Continuation Entries (CE) which
|
|
||||||
define where is further space with Rock Ridge data. Corrupted isofs
|
|
||||||
image can contain arbitrarily long chain of these, including a one
|
|
||||||
containing loop and thus causing kernel to end in an infinite loop when
|
|
||||||
traversing these entries.
|
|
||||||
|
|
||||||
Limit the traversal to 32 entries which should be more than enough space
|
|
||||||
to store all the Rock Ridge data.

Subject: KEYS: close race between key lookup and freeing
|
|
||||||
|
|
||||||
commit a3a8784454692dd72e5d5d34dcdab17b4420e74c upstream.
|
|
||||||
|
|
||||||
When a key is being garbage collected, it's key->user would get put before
|
|
||||||
the ->destroy() callback is called, where the key is removed from it's
|
|
||||||
respective tracking structures.
|
|
||||||
|
|
||||||
This leaves a key hanging in a semi-invalid state which leaves a window open
|
|
||||||
for a different task to try an access key->user. An example is
|
|
||||||
find_keyring_by_name() which would dereference key->user for a key that is
|
|
||||||
in the process of being garbage collected (where key->user was freed but
|
|
||||||
