Security Vulnerabilities
- CVEs Published In June 2025
In the Linux kernel, the following vulnerability has been resolved:
media: imx-jpeg: Align upwards buffer size
The hardware can support any image size WxH,
with arbitrary W (image width) and H (image height) dimensions.
Align upwards buffer size for both encoder and decoder.
and leave the picture resolution unchanged.
For decoder, the risk of memory out of bounds can be avoided.
For both encoder and decoder, the driver will lift the limitation of
resolution alignment.
For example, the decoder can support jpeg whose resolution is 227x149
the encoder can support nv12 1080P, won't change it to 1920x1072.
In the Linux kernel, the following vulnerability has been resolved:
drm/meson: encoder_cvbs: Fix refcount leak in meson_encoder_cvbs_init
of_graph_get_remote_node() returns remote device nodepointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
In the Linux kernel, the following vulnerability has been resolved:
drm/meson: encoder_hdmi: Fix refcount leak in meson_encoder_hdmi_init
of_graph_get_remote_node() returns remote device nodepointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
In the Linux kernel, the following vulnerability has been resolved:
bpf: fix potential 32-bit overflow when accessing ARRAY map element
If BPF array map is bigger than 4GB, element pointer calculation can
overflow because both index and elem_size are u32. Fix this everywhere
by forcing 64-bit multiplication. Extract this formula into separate
small helper and use it consistently in various places.
Speculative-preventing formula utilizing index_mask trick is left as is,
but explicit u64 casts are added in both places.
In the Linux kernel, the following vulnerability has been resolved:
bpf, x86: fix freeing of not-finalized bpf_prog_pack
syzbot reported a few issues with bpf_prog_pack [1], [2]. This only happens
with multiple subprogs. In jit_subprogs(), we first call bpf_int_jit_compile()
on each sub program. And then, we call it on each sub program again. jit_data
is not freed in the first call of bpf_int_jit_compile(). Similarly we don't
call bpf_jit_binary_pack_finalize() in the first call of bpf_int_jit_compile().
If bpf_int_jit_compile() failed for one sub program, we will call
bpf_jit_binary_pack_finalize() for this sub program. However, we don't have a
chance to call it for other sub programs. Then we will hit "goto out_free" in
jit_subprogs(), and call bpf_jit_free on some subprograms that haven't got
bpf_jit_binary_pack_finalize() yet.
At this point, bpf_jit_binary_pack_free() is called and the whole 2MB page is
freed erroneously.
Fix this with a custom bpf_jit_free() for x86_64, which calls
bpf_jit_binary_pack_finalize() if necessary. Also, with custom
bpf_jit_free(), bpf_prog_aux->use_bpf_prog_pack is not needed any more,
remove it.

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:
kunit: executor: Fix a memory leak on failure in kunit_filter_tests
It's possible that memory allocation for 'filtered' will fail, but for the
copy of the suite to succeed. In this case, the copy could be leaked.
Properly free 'copy' in the error case for the allocation of 'filtered'
failing.
Note that there may also have been a similar issue in
kunit_filter_subsuites, before it was removed in "kunit: flatten
kunit_suite*** to kunit_suite** in .kunit_test_suites".
This was reported by clang-analyzer via the kernel test robot, here:

In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/sec - don't sleep when in softirq
When kunpeng920 encryption driver is used to deencrypt and decrypt
packets during the softirq, it is not allowed to use mutex lock. The
kernel will report the following error:
