CVE-2025-38371
•
published on July 25, 2025
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Disable interrupts before resetting the GPU
Currently, an interrupt can be triggered during a GPU reset, which can
lead to GPU hangs and NULL pointer dereference in an interrupt context
as shown in the following trace:

CVE-2025-38371
•
published on July 25, 2025
In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Disable interrupts before resetting the GPU
Currently, an interrupt can be triggered during a GPU reset, which can
lead to GPU hangs and NULL pointer dereference in an interrupt context
as shown in the following trace:

CVE-2025-38370
•
published on July 25, 2025
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix failure to rebuild free space tree using multiple transactions
If we are rebuilding a free space tree, while modifying the free space
tree we may need to allocate a new metadata block group.
If we end up using multiple transactions for the rebuild, when we call
btrfs_end_transaction() we enter btrfs_create_pending_block_groups()
which calls add_block_group_free_space() to add items to the free space
tree for the block group.
Then later during the free space tree rebuild, at
btrfs_rebuild_free_space_tree(), we may find such new block groups
and call populate_free_space_tree() for them, which fails with -EEXIST
because there are already items in the free space tree. Then we abort the
transaction with -EEXIST at btrfs_rebuild_free_space_tree().
Notice that we say "may find" the new block groups because a new block
group may be inserted in the block groups rbtree, which is being iterated
by the rebuild process, before or after the current node where the rebuild
process is currently at.
Syzbot recently reported such case which produces a trace like the
following:

CVE-2025-38370
•
published on July 25, 2025
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix failure to rebuild free space tree using multiple transactions
If we are rebuilding a free space tree, while modifying the free space
tree we may need to allocate a new metadata block group.
If we end up using multiple transactions for the rebuild, when we call
btrfs_end_transaction() we enter btrfs_create_pending_block_groups()
which calls add_block_group_free_space() to add items to the free space
tree for the block group.
Then later during the free space tree rebuild, at
btrfs_rebuild_free_space_tree(), we may find such new block groups
and call populate_free_space_tree() for them, which fails with -EEXIST
because there are already items in the free space tree. Then we abort the
transaction with -EEXIST at btrfs_rebuild_free_space_tree().
Notice that we say "may find" the new block groups because a new block
group may be inserted in the block groups rbtree, which is being iterated
by the rebuild process, before or after the current node where the rebuild
process is currently at.
Syzbot recently reported such case which produces a trace like the
following:

CVE-2025-38370
•
published on July 25, 2025
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix failure to rebuild free space tree using multiple transactions
If we are rebuilding a free space tree, while modifying the free space
tree we may need to allocate a new metadata block group.
If we end up using multiple transactions for the rebuild, when we call
btrfs_end_transaction() we enter btrfs_create_pending_block_groups()
which calls add_block_group_free_space() to add items to the free space
tree for the block group.
Then later during the free space tree rebuild, at
btrfs_rebuild_free_space_tree(), we may find such new block groups
and call populate_free_space_tree() for them, which fails with -EEXIST
because there are already items in the free space tree. Then we abort the
transaction with -EEXIST at btrfs_rebuild_free_space_tree().
Notice that we say "may find" the new block groups because a new block
group may be inserted in the block groups rbtree, which is being iterated
by the rebuild process, before or after the current node where the rebuild
process is currently at.
Syzbot recently reported such case which produces a trace like the
following:

CVE-2025-38370
•
published on July 25, 2025
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix failure to rebuild free space tree using multiple transactions
If we are rebuilding a free space tree, while modifying the free space
tree we may need to allocate a new metadata block group.
If we end up using multiple transactions for the rebuild, when we call
btrfs_end_transaction() we enter btrfs_create_pending_block_groups()
which calls add_block_group_free_space() to add items to the free space
tree for the block group.
Then later during the free space tree rebuild, at
btrfs_rebuild_free_space_tree(), we may find such new block groups
and call populate_free_space_tree() for them, which fails with -EEXIST
because there are already items in the free space tree. Then we abort the
transaction with -EEXIST at btrfs_rebuild_free_space_tree().
Notice that we say "may find" the new block groups because a new block
group may be inserted in the block groups rbtree, which is being iterated
by the rebuild process, before or after the current node where the rebuild
process is currently at.
Syzbot recently reported such case which produces a trace like the
following:
------------[ cut here ]------------

CVE-2025-38369
•
published on July 25, 2025
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Check availability of workqueue allocated by idxd wq driver before using
Running IDXD workloads in a container with the /dev directory mounted can
trigger a call trace or even a kernel panic when the parent process of the
container is terminated.
This issue occurs because, under certain configurations, Docker does not
properly propagate the mount replica back to the original mount point.
In this case, when the user driver detaches, the WQ is destroyed but it
still calls destroy_workqueue() attempting to completes all pending work.
It's necessary to check wq-wq and skip the drain if it no longer exists.
