| In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc4-topology: Return error for invalid number of formats
When the number of input or output formats is zero,
sof_ipc4_widget_setup_comp_src() and sof_ipc4_widget_setup_comp_asrc()
print an error and jump to the cleanup label. At that point 'ret' is
still 0, because the earlier sof_ipc4_get_audio_fmt() call succeeded, so
the function returns success and the caller never finds out that the
widget setup actually failed.
Set ret to -EINVAL before the goto so the error gets reported. |

drm/rockchip: analogix_dp: Fix OF node reference leak via auto cleanup
Sashiko reported a reference leak in rockchip_dp_drm_encoder_enable(),
the of_get_child_by_name() function does not call of_node_put() in a
symmetrical way [1].
Fix the device node reference leak by using __free(device_node) to
automatically manage of_node_put() for all device nodes. |
| In the Linux kernel, the following vulnerability has been resolved:
memcg: move LRU size accounting on reparenting instead of copying it
When a memory cgroup is offlined its LRU folios are reparented to the
parent. lruvec_reparent_lru() splices the child's lists into the
parent's and credits the parent with the child's per-zone
lru_zone_size[], but never clears the child's copy, so the size is
copied rather than moved. lru_gen_reparent_memcg() does the same for
MGLRU.
The parent is left correct, credited with exactly the folios it took
over. The stale value sits on the child and nothing will correct it:
folio->memcg_data now resolves to the parent, so every later
update_lru_size() for those folios goes there.
Dying cgroups are not freed immediately and mem_cgroup_iter() still
walks them, so shrink_lruvec() keeps being called on them.
get_scan_count() reads the phantom counter through lruvec_lru_size() and
the scan loop then grinds through nr[] in SWAP_CLUSTER_MAX steps against
an empty list, for as long as the dead cgroup lives. Under MGLRU the
MGLRU scanner runs instead, but count_shadow_nodes() sums all of
NR_LRU_LISTS through lruvec_lru_size() and over-budgets the shadow node
limit just the same.
On one 251 GiB host a sweep of every mz->lru_zone_size[] found 380
counters describing folios on no list at all: 124777314 pages, 476 GiB,
1.89x the machine's RAM, across 57 cgroups. All were on memcgs with
CSS_DYING set and CSS_ONLINE clear, and parent/child pairs reported
byte-identical sizes.
LRU_UNEVICTABLE needs its size moved too. Its list is deliberately not
spliced because lruvec_init() poisons the head - the unevictable LRU is
imaginary and folios are never threaded on it - but the size is kept by
lruvec_add_folio()/lruvec_del_folio() and those folios account to the
parent from here on.
This depends on commit bf4ade7dbd76 ("memcg: keep folio's objcg same as
its node") and must not be backported ahead of it. Without that
invariant a folio's objcg can belong to another node, so a folio already
spliced onto the parent's list can still resolve to the child's lruvec
until the objcg's node is reparented in a later iteration of
memcg_reparent_objcgs(); clearing the child's counter early then lets
lruvec_del_folio() underflow it and trip the WARN_ONCE()/VM_BUG_ON() in
mem_cgroup_update_lru_size(). |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: RISC-V: Fix riscv_acpi_add_prt_dep() loop handling
The loop in riscv_acpi_add_prt_dep() includes error conditions that are
handled in a dubious - if not outright wrong - way, by continuining the
loop (which skips and misses the entry pointer update to point to the next
entry).
Rewrite the loop as a for loop (that handles the continuation correctly)
and wrap the condition and update statements using helper functions to make
it cleaner. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: xilinx_dma: Fix CPU stall in xilinx_dma_poll_timeout
Currently when calling xilinx_dma_poll_timeout with delay_us=0 and a
condition that is never fulfilled, the CPU busy-waits for prolonged time
and the timeout triggers only with a massive delay causing a CPU stall.
This happens due to a huge underestimation of wall clock time in
poll_timeout_us_atomic. Commit 7349a69cf312 ("iopoll: Do not use
timekeeping in read_poll_timeout_atomic()") changed the behavior to no
longer use ktime_get at the expense of underestimation of wall clock
time which appears to be very large for delay_us=0. Instead of timing
out after approximately XILINX_DMA_LOOP_COUNT microseconds, the timeout
takes XILINX_DMA_LOOP_COUNT * 1000 * (time that the overhead of the for
loop in poll_timeout_us_atomic takes) which is in the range of several
minutes for XILINX_DMA_LOOP_COUNT=1000000. Fix this by using a non-zero
value for delay_us. Use delay_us=10 to keep the delay in the hot path of
starting DMA transfers minimal but still avoid CPU stalls in case of
unexpected hardware failures.
One-off measurement with delay_us=0 causes the cpu to busy wait around 7
minutes in the timeout case. After applying this patch with delay_us=10
the measured timeout was 1053428 microseconds which is roughly
equivalent to the expected 1000000 microseconds specified in
XILINX_DMA_LOOP_COUNT.
Add a constant XILINX_DMA_POLL_DELAY_US for delay_us value. |

drm/msm: Fix task_struct reference leak in recover_worker
get_pid_task() increments the task reference count, but the
corresponding put_task_struct() was missing in the else branch,
leaking a reference on every GPU hang recovery.
Patchwork: https://patchwork.freedesktop.org/patch/730662/ |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/cxgb4: Free debugfs on registration failure
c4iw_alloc() creates the per-device debugfs tree (dev->debugfs_root via
setup_debugfs()), but it is removed only in c4iw_remove(), not in
c4iw_dealloc(). When RDMA device registration fails, the registration
worker's err_dealloc_ctx path calls c4iw_dealloc() directly, bypassing
c4iw_remove(), so the debugfs dentries leak and outlive the freed
c4iw_dev.
Move debugfs_remove_recursive() into c4iw_dealloc() so every path that
frees ctx->dev also removes its debugfs tree. |
| In the Linux kernel, the following vulnerability has been resolved:
media: amd: isp4: release partial allocations in isp4if_alloc_fw_gpumem()
isp4if_alloc_fw_gpumem() allocates several GPU memory pools in sequence.
If one of them fails, it jumps to error_no_memory and returns -ENOMEM
without releasing the pools that were already allocated, leaking them.
Release the already-allocated pools before returning. isp4if_gpu_mem_free()
is a no-op on pools that were not allocated, so calling
isp4if_dealloc_fw_gpumem() here safely frees exactly the pools that
succeeded.
isp4if_gpu_mem_free() previously logged an error for a NULL entry, which
is a normal case during partial-allocation cleanup, so make it silent. |
| The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 3.0.8 until 3.0.12, processScramAuthenticationInfo and processAuthenticationInfo compute the SCRAM ServerSignature or Digest rspauth verification result but log a mismatch and still deliver the response as authenticated. On a non-TLS or compromised transport, a peer that has not proved knowledge of the shared secret can therefore be accepted as the server. The fix rejects a present invalid value and computes Digest rspauth from the Authorization parameters actually sent, but verification remains unenforced when the value is absent, the sent parameters cannot be recovered, or Digest uses qop=auth-int. This issue is fixed in version 3.0.12. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix valid block count leak on data block allocation failure
In __allocate_data_block(), when allocating a new data block
(dn->data_blkaddr == NULL_ADDR), inc_valid_block_count() is
called first to increment total_valid_block_count and i_blocks.
If the subsequent f2fs_allocate_data_block() fails, the function
returns the error directly without rolling back the
already-incremented block counts, causing a permanent leak.
Fix this by calling dec_valid_block_count() to undo the
increment before returning the error. The condition
old_blkaddr == NULL_ADDR precisely identifies the case where
inc_valid_block_count() was called. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/ethosu: fix job completion fence cleanup
ethosu_ioctl_submit_job() allocates done_fence before validating buffer
handles. Errors after allocation call ethosu_job_err_cleanup(), which frees
the job but leaks the uninitialized fence.
A scheduler dependency error also lets ethosu_job_run() return before
dma_fence_init(). Normal cleanup then passes a zeroed refcount to
dma_fence_put().
Release done_fence in the common cleanup path and use
dma_fence_was_initialized() to distinguish initialized fences from raw
allocations.

| undici's experimental WebSocketStream client crashes the whole Node.js process when a remote peer closes the TCP connection without a WebSocket close handshake. On an unclean close the internal socket-close handler calls abort on the writable stream unconditionally and discards the returned promise, but per the WHATWG Streams standard aborting a locked writable returns a promise that rejects with a TypeError. Because the application holds a writer on that writable, which is the only way to write, the rejection is never observed and Node's default unhandled-rejection behavior terminates the process. An untrusted server can therefore crash a client with a single abrupt disconnect, with no authentication and no application mistake. This affects undici versions from 7.0.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should upgrade to undici 7.29.1 or 8.10.2. |

| In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Stop remote reader update when page swap fails
The remote swap_reader_page callback can return -EBUSY when the writer
moves the head before the remote catches it, particularly during an event
storm on a small buffer. __rb_get_reader_page_from_remote() currently
warns about that failure but continues with the unchanged reader ID and
rearranges the local page list as though the swap succeeded.
Handle the callback failure as a recoverable error. Report it with
pr_warn_ratelimited() and return NULL. Callers already handle a NULL reader
page as a failed attempt. This avoids splicing the same page as both the
previous and new reader without flooding the log under contention. |

iommufd: Fix wrong hwpt passed to iommufd_auto_response_faults on replace
iommufd_hwpt_replace_device() calls:
iommufd_auto_response_faults(hwpt, old_handle);
passing the *new* hwpt together with the handle of
the device's *old* domain. This should be a parameter mismatch:
1. Semantically, iommufd_auto_response_faults(x, handle) scans
x->fault's deliver list and response xarray for groups matching
"handle". A group is queued under the hwpt that was attached at
fault-delivery time. old_handle is fetched *before* the domain switch,
so its group lives on old->fault, not on the new hwpt->fault.
2. Historically, the first argument was "old". The routine was
introduced by commit b7d8833677ba ("iommufd: Fault-capable hwpt
attach/detach/replace") as __fault_domain_replace_dev() in
fault.c, correctly calling iommufd_auto_response_faults(old, curr).
Commit fb21b1568ada ("iommufd: Make attach_handle generic than
fault specific") moved this into iommufd_hwpt_replace_device() in
device.c and swapped it to "hwpt". This should be a refactor regression,
not an intentional change.
Fix this by passing "old" instead. |

block: skip sync_blockdev() on surprise removal in bdev_mark_dead()
bdev_mark_dead()'s @surprise == true means the device is already gone.
The filesystem callback fs_bdev_mark_dead() honours this and skips
sync_filesystem(), but the bare block device path (no ->mark_dead op)
lost its !surprise guard when the holder ->mark_dead callback was wired
up (see Fixes), and now calls sync_blockdev() unconditionally, which can
hang forever waiting on writeback that can no longer complete.
syzkaller hit this via nvme_reset_work()'s "I/O queues lost" path:
nvme_mark_namespaces_dead() -> blk_mark_disk_dead() ->
bdev_mark_dead(bdev, true) -> sync_blockdev() blocks in
folio_wait_writeback(), wedging the reset worker and every task waiting
on it.
Skip the sync on surprise removal, matching fs_bdev_mark_dead();
invalidate_bdev() still runs. Orderly removal (surprise == false) is
unchanged.
