| In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: cfg80211: Pass the PMK in binary instead of hex
Apparently the hex passphrase mechanism does not work on newer
chips/firmware (e.g. BCM4387). It seems there was a simple way of
passing it in binary all along, so use that and avoid the hexification.
OpenBSD has been doing it like this from the beginning, so this should
work on all chips.
Also clear the structure before setting the PMK. This was leaking
uninitialized stack contents to the device. |
| In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Do not swap cpu_buffer during resize process
When ring_buffer_swap_cpu was called during resize process,
the cpu buffer was swapped in the middle, resulting in incorrect state.
Continuing to run in the wrong state will result in oops.
This issue can be easily reproduced using the following two scripts:
/tmp # cat test1.sh
//#! /bin/sh
for i in `seq 0 100000`
do
echo 2000 > /sys/kernel/debug/tracing/buffer_size_kb
sleep 0.5
echo 5000 > /sys/kernel/debug/tracing/buffer_size_kb
sleep 0.5
done
/tmp # cat test2.sh
//#! /bin/sh
for i in `seq 0 100000`
do
echo irqsoff > /sys/kernel/debug/tracing/current_tracer
sleep 1
echo nop > /sys/kernel/debug/tracing/current_tracer
sleep 1
done
/tmp # ./test1.sh &
/tmp # ./test2.sh &
A typical oops log is as follows, sometimes with other different oops logs.

| In the Linux kernel, the following vulnerability has been resolved:
drm/meson: explicitly remove aggregate driver at module unload time
Because component_master_del wasn't being called when unloading the
meson_drm module, the aggregate device would linger forever in the global
aggregate_devices list. That means when unloading and reloading the
meson_dw_hdmi module, component_add would call into
try_to_bring_up_aggregate_device and find the unbound meson_drm aggregate
device.
This would in turn dereference some of the aggregate_device's struct
entries which point to memory automatically freed by the devres API when
unbinding the aggregate device from meson_drv_unbind, and trigger an
use-after-free bug:

arm64: ftrace: fix module PLTs with mcount
Li Huafei reports that mcount-based ftrace with module PLTs was broken
by commit:
a6253579977e4c6f ("arm64: ftrace: consistently handle PLTs.")
When a module PLTs are used and a module is loaded sufficiently far away
from the kernel, we'll create PLTs for any branches which are
out-of-range. These are separate from the special ftrace trampoline
PLTs, which the module PLT code doesn't directly manipulate.
When mcount is in use this is a problem, as each mcount callsite in a
module will be initialized to point to a module PLT, but since commit
a6253579977e4c6f ftrace_make_nop() will assume that the callsite has
been initialized to point to the special ftrace trampoline PLT, and
ftrace_find_callable_addr() rejects other cases.
This means that when ftrace tries to initialize a callsite via
ftrace_make_nop(), the call to ftrace_find_callable_addr() will find
that the `_mcount` stub is out-of-range and is not handled by the ftrace
PLT, resulting in a splat:
| ftrace_test: loading out-of-tree module taints kernel.
| ftrace: no module PLT for _mcount

Above issue is happens when enable bigalloc and inline data feature. As
commit 131294c35ed6 fixed delayed allocation bug in ext4_clu_mapped for
bigalloc + inline. But it only resolved issue when has inline data, if
inline data has been converted to extent(ext4_da_convert_inline_data_to_extent)
before writepages, there is no EXT4_STATE_MAY_INLINE_DATA flag. However
i_data is still store inline data in this scene. Then will trigger UAF
when find extent.
To resolve above issue, there is need to add judge "ext4_has_inline_data(inode)"
in ext4_clu_mapped(). |

udf: Detect system inodes linked into directory hierarchy
When UDF filesystem is corrupted, hidden system inodes can be linked
into directory hierarchy which is an avenue for further serious
corruption of the filesystem and kernel confusion as noticed by syzbot
fuzzed images. Refuse to access system inodes linked into directory
hierarchy and vice versa. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: audio-graph-card: fix refcount leak of cpu_ep in __graph_for_each_link()
The of_get_next_child() returns a node with refcount incremented, and
decrements the refcount of prev. So in the error path of the while loop,
of_node_put() needs be called for cpu_ep. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/omap: dss: Fix refcount leak bugs
In dss_init_ports() and __dss_uninit_ports(), we should call
of_node_put() for the reference returned by of_graph_get_port_by_id()
in fail path or when it is not used anymore. |
| In the Linux kernel, the following vulnerability has been resolved:
xen/privcmd: Fix a possible warning in privcmd_ioctl_mmap_resource()
As 'kdata.num' is user-controlled data, if user tries to allocate
memory larger than(>=) MAX_ORDER, then kcalloc() will fail, it
creates a stack trace and messes up dmesg with a warning.
Call trace:
-> privcmd_ioctl
--> privcmd_ioctl_mmap_resource
Add __GFP_NOWARN in order to avoid too large allocation warning.
This is detected by static analysis using smatch. |
