CVE-2022-50117 (published 2025-06-18)
In the Linux kernel, the following vulnerability has been resolved:

vfio: Split migration ops from main device ops

vfio core checks whether the driver sets some migration op (e.g.
set_state/get_state) and accordingly calls its op.

However, currently mlx5 driver sets the above ops without regards to its
migration caps.

This might lead to unexpected usage/Oops if user space may call to the
above ops even if the driver doesn't support migration. As for example,
the migration state_mutex is not initialized in that case.

The cleanest way to manage that seems to split the migration ops from
the main device ops, this will let the driver setting them separately
from the main ops when it's applicable.

As part of that, validate ops construction on registration and include a
check for VFIO_MIGRATION_STOP_COPY since the uAPI claims it must be set
in migration_flags.

HISI driver was changed as well to match this scheme.

This scheme may enable down the road to come with some extra group of
ops (e.g. DMA log) that can be set without regards to the other options
based on driver caps.

In the function rxe_create_qp(), rxe_qp_from_init() is called to

If an error occures before this point then the unwind will call

which will oops when trying to access the uninitialized spinlock.

The function rxe_create_qp calls rxe_qp_from_init. If some error

both scq and rcq to NULL.

Then rxe_create_qp calls rxe_put to handle qp. In the end,
rxe_qp_do_cleanup is called by rxe_put. rxe_qp_do_cleanup directly
accesses scq and rcq before checking them. This will cause
null-ptr-deref error.

'erased_blocks_bitmap' is never freed. As it is allocated at the same time
as 'used_blocks_bitmap', it is likely that it should be freed also at the
same time.

In the Linux kernel, the following vulnerability has been resolved:

intel_th: msu: Fix vmalloced buffers

After commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP") there's
a chance of DMA buffer getting allocated via vmalloc(), which messes up
the mmapping code:

> RIP: msc_mmap_fault [intel_th_msu]
> Call Trace:

Fix this by accounting for vmalloc possibility.

This happens because of data race. Each thread rewrite channels's
descriptor as soon as device_prep_dma_memcpy() is called. It leads to the
situation when the driver thinks that it uses right descriptor that
actually is freed or substituted for other one.

With current fixes a descriptor changes its value only when it has
been used. A new descriptor is acquired from vc->desc_issued queue that
is already filled with descriptors that are ready to be sent. Threads
have no direct access to DMA channel descriptor. Now it is just possible
to queue a descriptor for further processing.

To fix this, we can add a new HCI_DRAIN_WQ flag, and don't queue the
timeout workqueue while command workqueue is draining.

CVE-2022-50167 (published 2025-06-18)
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.

CVE-2022-50168 (published 2025-06-18)
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.

The simple_write_to_buffer() function will succeed if even a single

CVE-2022-50170 (published 2025-06-18)
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:
