CVSS v3.1 |
| File Viewer is a browser-native viewer for Office, PDF, CAD, archive, and other files in private and internal web applications. Prior to @file-viewer/doc 2.3.1 and msdoc-viewer 0.2.2, the legacy DOC renderer emitted document-controlled hyperlink targets into generated HTML after character escaping but without restricting URL schemes. A crafted legacy DOC file could place javascript:, vbscript:, data:, or another unsafe scheme in a rendered link, and script could execute in the embedding application's origin when a user clicked the link. The fix blocks external document links by default, allows only HTTP(S), mail, telephone, safe relative URLs, and internal bookmarks when external links are explicitly enabled, and applies mount-boundary sanitization as defense in depth. This issue is fixed in @file-viewer/doc 2.3.1 and msdoc-viewer 0.2.2. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Synchronize the error ISR against VINTF (de)init
A user VINTF is torn down by tegra241_cmdqv_deinit_vintf(), which runs from
the destroy callback and from the init-failure unwind in the alloc handler.
It clears the cmdqv->vintfs[] slot and lets the iommufd core free it, but
nothing serializes that against the error interrupt: tegra241_cmdqv_isr()
reads cmdqv->vintfs[idx] and dereferences the vintf. A concurrent error can
make the ISR read a slot mid-clear (a NULL deref) or use a vintf which is
about to be freed (a use-after-free).
deinit_vintf() also returns idx to the IDA before clearing the slot, so a
concurrent create that reuses idx can publish its new vintf into the slot,
only for this teardown to erase it again with the stale NULL store.
On the other end, tegra241_cmdqv_init_vintf() publishes a new vintf with a
plain store to the cmdqv->vintfs[] slot, and the ISR dereferences fields of
a published vintf such as vintf->base. A plain store gives no ordering on a
weakly-ordered CPU, and a stale VINTF_ERR_MAP bit on a reused idx can make
the ISR pick a vintf the moment it is published, before its fields are set
or tegra241_vintf_hw_init() runs.
The cmdqv->vintfs[0] slot stays NULL until tegra241_cmdqv_init_structures()
first creates VINTF0, so the slot 0 read needs the same NULL check.
Publish every slot with an smp_store_release(), and read each slot in the
ISR with an smp_load_acquire() under a NULL check, so the ISR always sees
a fully built vintf or NULL. Also make deinit_vintf() clear the slot, and
synchronize_irq() prior to returning idx to the IDA, so no vintf is freed
under a running handler and no reused idx is clobbered. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix overreads in ath12k_wmi_process_csa_switch_count_event()
There is no policy entry for WMI_TAG_PDEV_CSA_SWITCH_COUNT_STATUS_EVENT, so
the parse infrastructure does not enforce a minimum length for the event
struct. Additionally, the num_vdevs field is taken directly from firmware
and used as a loop bound over the vdev_ids array without checking that it
fits within the TLV payload. Either condition can cause an out-of-bounds
read.
Add a TLV policy entry for WMI_TAG_PDEV_CSA_SWITCH_COUNT_STATUS_EVENT so
the parse infrastructure enforces a minimum length for the fixed-size event
struct. Add a helper ath12k_wmi_tlv_data_len() to recover the payload
length of a parsed TLV from the header preceding its data pointer. Use it
in ath12k_wmi_process_csa_switch_count_event() to bound num_vdevs before
the loop.
Compile tested only. |

wifi: rtlwifi: pci: fix error path in rtl_pci_probe()
In the last error path in rtl_pci_probe(), the cleanup functions are
skipped due to a wrong goto label. Moreover, the successful call to
rtl_init_rfkill(), ieee80211_register_hw(), rtl_debug_add_one() have to
be reverted. Fix this issue by updating the labels and adding the
relevant cleanup functions to the last error path. |

| In the Linux kernel, the following vulnerability has been resolved:
RDMA/erdma: Hold QP references for AE and CM processing
AE QP fatal events and iWARP CM paths load QPs from dev->qp_xa
and then use or reference them outside the xarray lock.
erdma_destroy_qp() can drop the destroy-path reference and free QP
resources while such a lookup is in flight.
Add erdma_qp_get_by_qpn() to acquire a kref under the xarray
lock with kref_get_unless_zero(). Remove the QP from the xarray
before dropping the destroy-path reference so no new lookup can acquire
it while destruction waits for existing users. |
| In the Linux kernel, the following vulnerability has been resolved:
IB/isert: post the full-feature receive buffers after session registration
isert_put_login_tx() posts the full-feature receive buffers before
__transport_register_session() runs, so an initiator that does not wait
for the final Login Response can still have a SCSI command executed
against an se_session whose se_tpg is NULL - the same oops as the
previous patch, at target_submit+0xbe.
Post them from isert_get_rx_pdu(), which the previous patch already uses
to send that response, and post them before that send: the receive queue
is filled at the moment the initiator is told it may use it. Allocating
there keeps the existing property that a memory allocation failure cannot
happen once the final Login Response is on the wire.
The receive queue is already empty between the final Login Request and
isert_post_recvm(); this moves the second point later, from a median of
92 us to 172 us over 1200 logins. Only an initiator that sends before it
has been told to can reach that window, and on IB and RoCE its send is
retried there until the buffers appear - isert_rdma_accept() asks for
rnr_retry_count = 7. iWARP has no RNR flow control, so there the same
send terminates the connection instead.
Measured over rxe, 400 login cycles per run, with an initiator that does
not wait: an instrumented build counted no entries to isert_recv_done()
before the buffers are posted in 10 runs, where that initiator oopsed
8 of 10 unpatched runs and 5 of 10 with only the previous patch.
Not tested: iWARP, discovery sessions over iSER, and real HCAs. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/siw: Fix use-after-free in siw_accept()
siw_accept() looks up the QP supplied by userspace. If that QP is
already in RTS, the function jumps to error cleanup before associating
the incoming CEP with it.
The cleanup tests whether qp->cep is non-NULL and assumes the current
call installed the association. However, qp->cep can point to the CEP
of an existing connection. The cleanup then drops a reference from the
incoming cep, not qp->cep. Once the incoming endpoint loses its
remaining references, this can free it before the subsequent cep->qp
store, causing a use-after-free. It also clears the existing QP
association.
Only release the association reference when qp->cep is the incoming
CEP. This preserves an existing association and avoids accessing the
freed endpoint. |

module/dups: Fix use-after-free in kmod_dup_req lifetime handling
The kmod dups code uses RCU to ensure that a kmod_dup_req instance is freed
only after it is no longer referenced. When releasing an instance, the
kmod_dup_request_delete() function removes the kmod_dup_req from the
dup_kmod_reqs list, waits via synchronize_rcu() and finally frees it.
However, this doesn't work correctly because parallel users referencing the
instance in kmod_dup_request_exists_wait() don't enter an RCU read-side
critical section. This can result in a use-after-free.
The kmod_dup_request_exists_wait() function may need to hold a valid
reference to a kmod_dup_req instance across a blocking wait until the
corresponding modprobe command completes. This makes it unsuitable for RCU.
Fix the issue by changing the lifecycle management of kmod_dup_req to use
reference counting. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/gfx6: Use PFP on the compute queues too
On GFX6, the compute rings use the same CP path as
the graphics ring. The only difference is that they
don't support draw commands. (As opposed to GFX7 and
newer which have a separate command parser that is
called MEC for compute queues.)
This means that we have to take into consideration
that the PFP also exists on compute queues on GFX6:
Use PFP for register writes on both graphics and
compute queues.
In the pipeline sync, use the PFP to wait for the
previous fence (and not the ME) to prevent the PFP
from starting to execute the next submission while
the ME is still in the previous submission.
After a VM flush, emit PFP_SYNC_ME on compute
queues as well. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: don't clobber the extent buffer when zeroing it out
On a zoned filesystem a freed-but-still-dirty tree block is written out
as zeros (EXTENT_BUFFER_ZONED_ZEROOUT) only to keep the zone write
pointer advancing. btree_csum_one_bio() implemented this by memzeroing
the extent buffer's own folios before submission.
That destroys the in-memory buffer while it may still be referenced. In
particular btrfs_free_tree_block() can run on it afterwards and reads
the header to add a delayed reference; once the header has been zeroed
it frees bytenr 0 and corrupts the extent tree (the
btrfs_header_bytenr(buf) != 0 ASSERT in btrfs_free_tree_block(), or an
"unable to find ref" abort). It is flaky and reproduces under fsstress,
e.g. generic/461 and generic/013.
Write the zeros to disk from the shared zero page instead and leave the
extent buffer content untouched, so any later reference - including the
delayed reference from btrfs_free_tree_block() - still sees a valid
header. end_bbio_meta_write() now clears writeback on the buffer's own
folios, as the bio no longer carries them. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Clear Present bit before tearing down copied context entry
copied_context_tear_down() zeroes the 128-bit context entry with
context_clear_entry() while the Present bit is still set, and only then
issues the context-cache and IOTLB invalidations. This leaves a window
in which hardware can fetch a torn entry, with some fields already zeroed
while Present is still set, leading to unpredictable behaviour or
spurious faults. While x86 provides strong write ordering, the compiler
may reorder the writes to the two 64-bit halves of the entry, and the
hardware fetch is not guaranteed to be atomic with respect to multiple
CPU writes.
There is no cacheline flush before the invalidation either, so on an
IOMMU without coherent access to the context table the zeroed entry may
not be visible to hardware at the point the invalidation is submitted.
Apply the same ownership handshake described in the VT-d spec, Section
6.5.3.3 ("Guidance to Software for Invalidations"): clear only the Present
bit, flush it out to the IOMMU, perform the invalidations, and only then
zero the remainder of the entry. |

| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: reject out-of-range evcn in mi_enum_attr()
In mi_enum_attr(), the start/end VCN validation for non-resident
attributes is:
if (svcn > evcn + 1) goto out;
When evcn is U64_MAX the "evcn + 1" expression wraps to 0 and any svcn
passes the check. For evcn values close to U64_MAX (but not equal to it)
the right-hand side is still a meaningless near-wrap upper bound, so a
malformed on-disk attribute with svcn == 0 and evcn near U64_MAX can pass
mi_enum_attr() unrejected.
VCN (virtual cluster number) is a cluster index, so any valid evcn is
bounded by the volume's total cluster count, which ntfs3 holds in
sbi->used.bitmap.nbits (set up in ntfs_init_from_boot() before any caller
of mi_enum_attr() runs). Reject evcn values that fall outside this range.
However, an empty non-resident attribute (no allocated clusters) is
legitimately encoded with svcn == 0 and evcn == -1 (U64_MAX), e.g. via
attr->nres.evcn = cpu_to_le64((u64)vcn - 1) with vcn == 0. That sentinel
must keep passing, so exclude evcn == U64_MAX from the range check. The
existing "svcn > evcn + 1" test still tolerates the sentinel ("0 > 0" is
false) and continues to require svcn == 0 for it, while the range check
rejects every other out-of-range evcn and thereby also defuses the
"evcn + 1" wraparound.
svcn does not need its own bound: once evcn < nbits, "svcn > evcn + 1"
implies svcn <= nbits.

mailbox: riscv-sbi-mpxy: validate RPMI notification lengths
The SBI return value controls how many bytes are copied from shared
memory into the RPMI notification buffer. It is not validated against
the negotiated shared-memory size before that copy. The event walker
also uses a reversed loop condition and can inspect a short event record.
Validate the complete notification length before copying it, iterate only
while a full event header remains, and stop when a declared event payload
extends beyond the copied notification data. |
