power: supply: ab8500_fg: fix use-after-free on remove
ab8500_fg_remove() destroys the driver workqueue while the threaded
interrupt handlers are still armed; they are devm-managed and freed
only after ->remove() returns, so a handler that fires in that
window queues work on the freed workqueue.
Tear the workqueue down through devm instead, registering its cleanup
after the power supply and before the interrupt requests. devm then
frees the interrupts first, so the handlers can no longer queue work,
before disabling the delayed and plain work items and destroying the
workqueue. Disabling the items, rather than cancelling them, keeps
them disabled so no producer (including the power-supply
external_power_changed callback) can requeue them.

| Info-ZIP Zip 3.0, when the -T and -TT command-line options are used, allows attackers to cause a denial of service (invalid free and application crash) or possibly have unspecified other impact because of an off-by-one error. NOTE: it is unclear whether there are realistic scenarios in which an untrusted party controls the -TT value, given that the entire purpose of -TT is execution of arbitrary commands |

drm/nouveau/uvmm: fix premature region free on failed OP_UNMAP_SPARSE
In nouveau_uvmm_bind_job_submit()'s OP_UNMAP_SPARSE arm, op->reg is set
from nouveau_uvma_region_find(), which only looks the region up and takes
no reference; a region's sole reference is its membership in
uvmm->region_mt. Two failure paths leave op->reg set: the -ENOENT check
when the region is busy, and the drm_gpuvm_sm_unmap_ops_create() failure.
The sibling nouveau_uvmm_sm_unmap_prepare() failure just below clears
op->reg; these two do not.
unwind_continue steps back one op, so the failing op is skipped by the
unwind loop and its op->reg stays set. nouveau_uvmm_bind_job_cleanup()
then enters its if (op->reg) branch and calls nouveau_uvma_region_remove()
and nouveau_uvma_region_put() on it, dropping the tree's sole reference
and freeing a region this job never created. The comment above the
cleanup loop documents the broken invariant: op->reg must be NULL on
submit failure.
This frees a live region on an unrelated failure, reachable single-job
when drm_gpuvm_sm_unmap_ops_create() returns -ENOMEM; if another job owns
the same region, its cleanup then removes and puts the freed region, a
use-after-free. Clear op->reg on both failure paths. |

drm/amdkfd: Fix error path at svm_migrate_copy_to_ram
If page migration from device to sys ram fails for some reasons driver needs
release and unlock allocated system pages. To do that driver should use page
physical address, or pfn, then get struct page*. Current driver uses dma
address(for adev) that is not correct with IOMMU enabled, or even in general.
The patch releases and unlocks allocated system pages based on where migration
failed by struct page* of sys ram pages. Also dma_unmap correspodent system
ram pages at error path. |

f2fs: fix folio_nr_pages() race after put in large folio invalidate
Our v6.18 based Android system is continuely suffering livelock and bad
page stat as shown in[1] which related to broken xarray slot status. By
investigating big folio operations within f2fs, we find below races and
fix it by get the nr_pages before drop the refcount and folio_lock.
f2fs_get_read_data_folio() calls f2fs_folio_put() before
folio_nr_pages() when invalidating a large folio from the page cache.
That unlocks the folio and drops the caller reference, leaving a window
where a concurrent truncate or folio split can shrink the compound folio
or free it before the invalidate range is computed. An undersized range
then leaves split sub-folios in mapping->i_pages, which can later
interact badly with truncate and reclaim (stale xarray entries and bad
page state when folio->mapping no longer matches the mapping being
truncated).

media: i2c: ov7740: fix use-after-destroy in remove
The ov7740_remove() function had a severe teardown order bug where it
destroyed the driver's mutex before freeing the V4L2 control handler
which relies on that mutex, leading to a use-after-destroy kernel panic.
Furthermore, the driver explicitly called v4l2_ctrl_handler_free() and
mutex_destroy() sequentially, but then called ov7740_free_controls()
which invokes both of them a second time, resulting in a double-free.
This patch fixes the issue by unregistering the subdevice first, and
relying exclusively on ov7740_free_controls() to safely tear down the
mutex and control handler in the correct order. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Avoid double completion in async IOCB timeout
qla2x00_async_iocb_timeout() tries to abort a timed-out async IOCB. When
qla24xx_async_abort_cmd() fails, both the SRB_LOGIN_CMD path and the
SRB_CTRL_VP/default path scan outstanding_cmds[] for the SRB and then
call sp->done(sp, QLA_FUNCTION_TIMEOUT) unconditionally, without checking
whether the SRB was actually found and removed.
If the response ISR completes the same handle first, it removes the SRB
under qp_lock_ptr and runs sp->done() -> complete(sp->comp). The
submitter qla24xx_control_vp() wakes from wait_for_completion(), clears
sp->comp, drops its reference and returns, reclaiming the on-stack
completion. The timer reference keeps the SRB alive across the timeout
handler, but not the submitter's stack. The timeout then issues a second
sp->done() -> qla_ctrlvp_sp_done(), which evaluates "if (sp->comp)
complete(sp->comp)"; with the pointer loaded before the submitter's NULL
store, complete() writes into the freed stack frame, a use-after-free.
Track whether this path removed the SRB from outstanding_cmds and only
call sp->done() when it did, so the command is completed exactly once by
whichever path owns it. This mirrors the sp_found guard already used in
qla24xx_abort_iocb_timeout(). |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Quiesce response IRQ before freeing request queue
qla2xxx_delete_qpair() deletes the request queue before the response
queue. qla25xx_delete_req_que() frees the request queue memory
(kfree(req) in qla25xx_free_req_que()), but the response-queue MSI-X is
only released later, in qla25xx_free_rsp_que(). In that window the
response interrupt can still fire, qla2xxx_msix_rsp_q() queues
qpair->q_work, and qla_do_work() -> qla24xx_process_response_queue()
dereferences the now-freed rsp->req (LOGINOUT/CT/ELS entries and the
status path), a use-after-free.
The cancel_work_sync() added for the qpair teardown lives in the
response free path, which runs after the request queue is already freed,
so it does not protect rsp->req.
Release the response-queue interrupt and flush qpair->q_work before
deleting the request queue, so no late completion can reach the freed
request queue. Clearing have_irq makes the subsequent
qla25xx_free_rsp_que() skip its free_irq(), and the firmware
queue-delete order (request then response) is preserved; the
request-delete mailbox completes on the default vector and is unaffected
by dropping the qpair response interrupt early. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: unsubscribe the channel-kill event before the fence context
nouveau_channel_del() tears the fence context down first and only drops
the channel-kill subscription later, in the middle of the nvif object
teardown:
if (chan->fence)
nouveau_fence(chan->cli->drm)->context_del(chan);
...
nvif_object_dtor(&chan->vram);
nvif_event_dtor(&chan->kill);
The subscribed handler is nouveau_channel_killed(), which calls
nouveau_channel_kill() and from there nouveau_fence_context_kill() on
chan->fence. A kill event delivered in that window takes fctx->lock and
walks fctx->pending on a fence context that context_del() has already
freed.
Nothing reaches this below Fermi today, because the subscription is
gated on FERMI_CHANNEL_GPFIFO and nothing kills a channel there. On
Fermi and newer the window is real but narrow, since a kill has to land
exactly while the channel is being destroyed. That is reason enough on
its own, which is why this carries a Fixes: tag. The last patch in this
series subscribes Tesla channels as well; nothing kills those today, so
it does not widen the exposure now, but it is the groundwork for a
recovery path that would, and the ordering is better fixed before that
lands than alongside it.
Drop the subscription before anything it depends on is torn down. |

drm/pagemap: Fix folio allocation fallback and use-after-put
drm_pagemap_migrate_populate_ram_pfn() had two issues when populating
RAM PFNs with higher-order folios:
1. The higher-order vma_alloc_folio()/folio_alloc() calls did not pass
__GFP_NOWARN, so a THP allocation failure under memory pressure
would spam the kernel log, and there was no fallback path despite a
TODO comment stating one was needed. Add __GFP_NOWARN to the
higher-order allocation and, on failure, fall back to order-0
allocations for the entire range originally covered by the failed
higher-order allocation, leaving MIGRATE_PFN_COMPOUND unset for
those PFNs.
2. In the free_pages error path, order was computed via
folio_order(page_folio(page)) *after* put_page(page) had already
dropped the reference, resulting in a use-after-free/put when that
was the last reference on the page. Compute order before releasing
the page.
Introducing the fallback in 1. also requires the source page array
handed to ->copy_to_ram() to be built differently. Both callers only
populated the entry at the head of each source folio, relying on the
copy callback to derive the rest of the folio from the order recorded
in the matching drm_pagemap_addr. Once the destination has been demoted
to order-0 folios the drm_pagemap_addr entries are per-page, so a source
page is needed for every one of them; leaving them NULL makes the copy
callback stop after the first page and the remainder of the range is
never copied.
The source folio is only split later, by migrate_vma_pages() /
migrate_device_pages(), so its order cannot be used to detect the
demotion - test the destination for MIGRATE_PFN_COMPOUND instead. Factor
the array population out into drm_pagemap_migrate_populate_src_pages()
and use it from both drm_pagemap_evict_to_ram() and
__drm_pagemap_migrate_to_ram(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Add TLB flush after MES queue eviction/suspension
MES (Micro Engine Scheduler) does not perform heavy-weight TLB
invalidation after unmapping queues, unlike HWS which does this
automatically. This causes a race condition where in-flight DMA
descriptors can access memory that has been unmapped, leading to page
faults and GPU queue hangs during SVM page migration.
The issue manifests as KFDSVMRangeTest.MultiThreadMigrationTest
failures on gfx1151 (Strix Point) with XNACK mode 1 enabled - the GPU
compute queue hangs with packets submitted but never consumed.
Add kfd_flush_tlb() calls after MES queue removal in two locations:
- evict_process_queues_cpsch(): after all queues removed during eviction
- suspend_queues(): after debug/criu queue suspension (with mem_fence barrier)
This ensures all in-flight memory accesses from unmapped queues are
flushed before memory is freed or migrated.

| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Hold vport reference in qla24xx_report_id_acquisition()
In the format 1 path, the virtual port is located on ha->vp_list while
holding vport_slock, but the lock is dropped before vp is used:
qla_update_host_map() is called and VP_IDX_ACQUIRED/REGISTER_FC4_NEEDED/
REGISTER_FDMI_NEEDED are set on vp. No reference is taken across that
window, so a concurrent qla24xx_deallocate_vp_id() can tear the vport
down and free it, leading to a use-after-free.
Take a vport reference (vref_count) under vport_slock when the matching
vp is found, and drop it after the last use of
vp. qla24xx_deallocate_vp_id() waits for vref_count to reach zero before
unlinking and freeing the vport, so the pointer stays valid. This
matches the reference idiom already used by the other ha->vp_list
traversals. |
| In the Linux kernel, the following vulnerability has been resolved:
media: cx23885: cancel NetUP CI work before teardown
netup_ci_exit() frees a netup_ci_state while its work item,
netup_read_ci_status(), may still be pending or running on the system
workqueue. The worker obtains the state with container_of() and
dereferences it, so it must not outlive the state.
netup_ci_init() queues the initial status read, and CI GPIO interrupts
subsequently queue the same work from netup_ci_slot_status(). During
remove, cx23885_finidev() calls free_irq() before the CI device is
unregistered. free_irq() prevents further IRQ handlers from running,
but does not drain work queued previously, so the worker can run after
netup_ci_exit() frees the state.
Call cancel_work_sync() before dvb_ca_en50221_release() and kfree().

| In the Linux kernel, the following vulnerability has been resolved:
media: cobalt: Avoid freeing ALSA private data twice
snd_cobalt_card_create() stores cobsc in sc->private_data and installs
snd_cobalt_card_private_free() as sc->private_free. From that point,
snd_card_free(sc) releases cobsc through the ALSA card cleanup path.
If cobalt_alsa_init() fails after snd_cobalt_card_create(), the
err_exit_free path calls snd_card_free(sc) and then kfree(cobsc). That
second free releases the same object again.
Remove the explicit kfree(cobsc) and leave ownership with the ALSA card.
This issue was found by a static analysis checker and confirmed by
manual source review. |
