CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
net: xilinx: axienet: Free outstanding DMA buffers on dmaengine stop
In the dmaengine path the driver pre-submits RX buffers and holds
in-flight TX buffers whose SKBs are DMA-mapped by the driver and freed
only in the completion callbacks. On ndo_stop() dmaengine_terminate_sync()
aborts these descriptors without running their callbacks, and the driver
then frees only the ring shells, leaking every SKB still owned by the
engine and its DMA mapping on each ifdown. With 128 RX buffers pre-posted
per channel, the mapping leak can eventually exhaust a limited IOMMU
aperture.
Clear the slot's skb in the TX and RX callbacks so a non-NULL skb marks a
slot that still owns a live, DMA-mapped buffer, and on stop unmap and free
every such buffer.
axienet_dma_rx_cb() runs from the DMA tasklet and re-arms the RX ring on
each completion, so it can race axienet_stop(): a completion may submit a
fresh buffer after dmaengine_terminate_sync() has returned, leaving the
channel armed with a buffer the teardown then frees while the engine may
still write into it (dma_release_channel() does not stop it either). Add a
lock that axienet_dma_rx_cb() holds across the @stopping check and the
resubmit, and axienet_stop() holds to set @stopping before terminating.
Once @stopping is set no callback can arm a new buffer, and any armed just
before is aborted by the terminate, so teardown only frees buffers the
engine no longer owns. |
| In the Linux kernel, the following vulnerability has been resolved:
net: sparx5: free the matchall entry on destroy
sparx5_tc_matchall_replace() allocates a struct sparx5_mall_entry for
every offloaded matchall filter and adds it to sparx5->mall_entries.
sparx5_tc_matchall_destroy() removes the entry from the list, but never
frees it, so the entry of every deleted mirror and goto matchall filter
is leaked.
Free the entry after unlinking it.
The leak was discovered by an AI code review agent, and reproduced with
kmemleak on a lan969x EV board (EV23X71A) by repeatedly adding and
deleting matchall mirror and goto filters. With the fix, kmemleak no
longer reports the leak. |
| Improper input validation in Smart Switch prior to version 3.7.72.6 allows adjacent attackers to access sensitive data. |
| Improper input validation in MPEG4 codec in libsavsvc.so prior to SMR Aug-2026 Release 1 allows local attackers to write out-of-bounds memory. |
| A weakness has been identified in SourceCodester Simple Doctors Appointment System 1.0. The affected element is an unknown function of the file /admin/ajax.php?action=set_appointment. This manipulation of the argument ID causes sql injection. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. |
| Improper input validation in Samsung Message prior to SMR Aug-2026 Release 1 allows physical attackers to access sensitive information. |
| Improper input validation in VC1 codec in libsavsvc.so prior to SMR Aug-2026 Release 1 allows local attackers to write out-of-bounds memory. |
| Improper access control in SmartThings prior to version 1.8.47.24 allows local attackers to access sensitive information. |
| Incorrect conversion between numeric types in VC1 codec in libsavsvc.so prior to SMR Aug-2026 Release 1 allows local attackers to write out-of-bounds memory. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: glink: fix use-after-free of ucsi on remove
The pmic_glink client is released by the devres cleanup, which runs
after pmic_glink_ucsi_remove() has returned, so its notification
callbacks can queue work until then. Work that runs after
ucsi_unregister() has been called touches freed state: it dereferences
the connector array that ucsi_unregister() freed, or registers and
unregisters the instance a second time.
Disable both work items with disable_work_sync() before unregistering,
and unregister only if the instance is still registered.
