Security Vulnerabilities - CVEs Published In June 2024
In the Linux kernel, the following vulnerability has been resolved:
lib/test_hmm.c: handle src_pfns and dst_pfns allocation failure
The kcalloc() in dmirror_device_evict_chunk() will return null if the
physical memory has run out. As a result, if src_pfns or dst_pfns is
dereferenced, the null pointer dereference bug will happen.
Moreover, the device is going away. If the kcalloc() fails, the pages
mapping a chunk could not be evicted. So add a __GFP_NOFAIL flag in
kcalloc().
Finally, as there is no need to have physically contiguous memory, Switch
kcalloc() to kvcalloc() in order to avoid failing allocations.

In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt
In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the
resp_pkts queue and then a decision is made whether to run the completer
task inline or schedule it. Finally the skb is dereferenced to bump a 'hw'
performance counter. This is wrong because if the completer task is
already running in a separate thread it may have already processed the skb
and freed it which can cause a seg fault. This has been observed
infrequently in testing at high scale.
This patch fixes this by changing the order of enqueuing the packet until
after the counter is accessed.

In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix UAF for cq async event
The refcount of CQ is not protected by locks. When CQ asynchronous
events and CQ destruction are concurrent, CQ may have been released,
which will cause UAF.
Use the xa_lock() to protect the CQ refcount.

In the Linux kernel, the following vulnerability has been resolved:
drm: vc4: Fix possible null pointer dereference
In vc4_hdmi_audio_init() of_get_address() may return
NULL which is later dereferenced. Fix this bug by adding NULL check.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

In the Linux kernel, the following vulnerability has been resolved:
media: atomisp: ssh_css: Fix a null-pointer dereference in load_video_binaries
The allocation failure of mycs->yuv_scaler_binary in load_video_binaries()
is followed with a dereference of mycs->yuv_scaler_binary after the
following call chain:
sh_css_pipe_load_binaries()
|-> load_video_binaries(mycs->yuv_scaler_binary == NULL)
|
|-> sh_css_pipe_unload_binaries()
|-> unload_video_binaries()
In unload_video_binaries(), it calls to ia_css_binary_unload with argument
&pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the
same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer
dereference is triggered.

In the Linux kernel, the following vulnerability has been resolved:
net: bridge: mst: fix vlan use-after-free
syzbot reported a suspicious rcu usage[1] in bridge's mst code. While
fixing it I noticed that nothing prevents a vlan to be freed while
walking the list from the same path (br forward delay timer). Fix the rcu
usage and also make sure we are not accessing freed memory by making
br_mst_vlan_set_state use rcu read lock.
