Upgrading to version 0.9.8-hotfix1 and 0.9.8 mitigates this issue. This patch is called 788cace0af816aa972a713a4631c57f16f895e6b. Upgrading the affected component is recommended. |
| A flaw has been found in code-projects Online Food Order System 1.0. The impacted element is an unknown function of the file delete_food_items1.php. Executing a manipulation of the argument checkbox can lead to sql injection. The attack can be executed remotely. The exploit has been published and may be used. |
| In the Linux kernel, the following vulnerability has been resolved:
vduse: Fix race in vduse_dev_msg_sync and vduse_dev_read_iter
There is one race case in vduse_dev_msg_sync and vduse_dev_read_iter:
vduse_dev_read_iter():
lock(msg_lock);
dequeue_msg(send_list);
unlock(msg_lock);
vduse_dev_msg_sync():
wait_timeout() finish
lock(msg_lock);
check msg->complete is false
list_del(msg); <- double list_del() crash!
To fix this case, we shall ensure vduse_msg is on send_list or recv_list
outside the msg_lock critical section. |
| In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Fill first free targets[] slot during auto-discovery
Any invalid endpoint decoder pointer in the target array of an active
region is not allowed by cxl driver. This means cxl driver always
assumes the first p->nr_targets entries of the target array in an
auto-assembly region are valid. However, there are scenarios that could
leave NULL endpoint decoder pointer holes in the target array.
1. When cxl_cancel_auto_attach() removes an endpoint decoder from a
target array, the target slot is set to NULL. If the removed endpoint
decoder is not the last element in the target array, the target array
will contain a NULL hole.
2. When a auto-assembly region removes an assigned endpoint decoder, if
the removed endpoint decoder is not the last element in the target
array, always remains a NULL hole in the target array.
When a NULL pointer hole exists in a region's target array, it
introduces two potential problems:
1. Access an endpoint decoder via a NULL pointer. it always trigger
calltrace like that.
Oops: general protection fault, probably for non-canonical address 0xdffffc0000000008: 0000 [#1] SMP KASAN PTI

2. Not having enough valid endpoint decoders attached to an
auto-assembly region. if an auto-assembly region is created with lock
flag or assigned endpoint decoder with lock flag, which means
assigned endpoint decoder will not be reset during detaching, they
could re-attach to the auto-assembly region again. But cxl region
driver relies on p->nr_targets to verify whether the required number
of endpoint decoders has been attached, and NULL endpoint decoder
pointers are still counted in that case.
To fix above issues, adjust cxl_region_attach_auto() logic to find the
first free target slot for endpoint decoder attachment, this ensures
NULL holes in the target array are filled, rather than adding new
endpoint decoders at the tail of the target array. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_hfsc: Don't make class passive twice
update_vf() is called from two places for the same class during a single
dequeue when the class's child qdisc (e.g. codel/fq_codel) drops its last
packets while dequeuing:
1. The child calls qdisc_tree_reduce_backlog(), which, now that the child
is empty, invokes hfsc_qlen_notify() -> update_vf(cl, 0, 0) and turns
the class passive (cl_nactive is decremented up the hierarchy).
2. hfsc_dequeue() then calls update_vf(cl, qdisc_pkt_len(skb), cur_time)
to charge the dequeued bytes.
On the second call the class is already passive, but its child qdisc is
still empty, so update_vf() arms go_passive again:
if (cl->qdisc->q.qlen == 0 && cl->cl_flags & HFSC_FSC)
go_passive = 1;
The leaf is then skipped by the cl_nactive == 0 check inside the loop,
which does not clear go_passive, so the stale go_passive propagates to the
parent and decrements its cl_nactive a second time. A parent that still
has other active children is driven to cl_nactive == 0 and removed from
the vttree, even though those siblings are still backlogged. They are
never dequeued again and the qdisc stalls.
Fix this by only arming go_passive when the class is actually active, so an
already-passive class no longer triggers a second passive transition. The
byte accounting (cl->cl_total += len) still runs for every ancestor, so
dequeued bytes continue to be counted exactly once. |
| In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Block region delete during region creation
Expand the range lock, rename it "regions_lock", to disable region deletion
in the critical period between construct_region() and attach_target(), as
well as the period between device_add() and registering the remove actions.
Otherwise, userspace can confuse the kernel. It can violate the assumption
the region stays registered through the completion of cxl_add_to_region().
It can violate the assumption that devm_add_action_or_reset() is working
with a live 'struct cxl_region'.
It is ok for the region to disappear outside of those windows as that
mirrors device hotplug flows where the proper locks are held. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: seq: Fix kernel heap address leak in bounce_error_event()
The comment above bounce_error_event() documents that user clients
should receive SNDRV_SEQ_EVENT_BOUNCE with the original event embedded
as variable-length data, while kernel clients should receive
SNDRV_SEQ_EVENT_KERNEL_ERROR with a quoted kernel pointer.
However, the implementation unconditionally uses
SNDRV_SEQ_EVENT_KERNEL_ERROR with data.quote.event set to the raw
struct snd_seq_event pointer for all clients. When a bounce error
event is delivered to a USER_CLIENT via snd_seq_read(), the kernel
heap address in data.quote.event is exposed to userspace through
copy_to_user() in the fixed-length branch.
This is a distinct leak path from the one addressed by commit
705dd6dcbc0e ("ALSA: seq: Clear variable event pointer on read"),
which sanitizes data.ext.ptr in the variable-length branch of
snd_seq_read(). The bounce_error_event() leak uses fixed-length
events that take the else branch where no sanitization occurs.
Differentiate the bounce event by client type. For USER_CLIENT,
send SNDRV_SEQ_EVENT_BOUNCE with SNDRV_SEQ_EVENT_LENGTH_VARIABLE
and data.ext pointing to the original event. The variable-length
path in snd_seq_event_dup() copies the event data into chained
cells, and snd_seq_expand_var_event() copies only the content --
never the pointer -- to userspace. For KERNEL_CLIENT, keep the
existing SNDRV_SEQ_EVENT_KERNEL_ERROR behavior with the quoted
pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
net: pfcp: allocate per-cpu tstats for PFCP netdevs
PFCP uses dev_get_tstats64() as its ndo_get_stats64 callback, but
pfcp_link_setup() does not request NETDEV_PCPU_STAT_TSTATS. The net
core therefore leaves dev->tstats NULL for PFCP devices.
Creating a PFCP rtnetlink device can immediately ask the new netdev for
stats while building the RTM_NEWLINK notification. That reaches
dev_get_tstats64() and dereferences the NULL dev->tstats pointer.
Set pcpu_stat_type to NETDEV_PCPU_STAT_TSTATS during PFCP link setup so
the net core allocates the storage expected by dev_get_tstats64(). |
| A vulnerability was found in SourceCodester Online Book Store System 1.0. This vulnerability affects unknown code of the file /admin/index.php?page=site_settings of the component System Settings Module. The manipulation results in cross site scripting. The attack can be executed remotely. The exploit has been made public and could be used. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Fix FRMR set pinned push error path
Add destruction of FRMR handles in case the push to the pool fails.
This prevents resources leak in case pool page allocation fails. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_qca: fix NULL pointer dereference in qca_dmp_hdr() for non-serdev device
hu->serdev is NULL for hci_uart attached via non-serdev paths, but
qca_dmp_hdr() unconditionally dereferences hu->serdev->dev.driver->name,
causing a NULL pointer dereference.
Fix by guarding the dereference with a NULL check and falling back to
"hci_ldisc_qca" for the non-serdev case. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: Fix possible NULL pointer dereference in mt7996_mac_write_txwi_80211()
For injected frames (e.g. via radiotap), mac80211 can pass
info->control.vif = NULL, as explicitly noted in struct ieee80211_tx_info.
Check vif pointer before executing ieee80211_vif_is_mld() in
mt7996_mac_write_txwi_80211 routine in order to avoid a possible NULL
pointer dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_qca: fix NULL pointer dereference in qca_setup() for non-serdev device
hu->serdev is NULL for hci_uart attached via non-serdev paths, but
qca_setup() unconditionally calls serdev_device_get_drvdata(hu->serdev)
and dereferences the result, causing a NULL pointer dereference.
Fix by guarding the dereference with a NULL check, consistent with the
rest of qca_setup(). |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7925: validate skb length in testmode query
In mt7925_tm_query(), the response skb from mt76_mcu_send_and_get_msg()
is used in a memcpy without validating its length:
memcpy(evt_resp, skb->data + 8, MT7925_EVT_RSP_LEN);
where MT7925_EVT_RSP_LEN is 512. If the firmware returns a response
shorter than 520 bytes (8 + 512), this reads beyond the skb data
buffer. The over-read data is then returned to userspace via nla_put()
in mt7925_testmode_dump().
Add a length check before the memcpy to ensure the skb contains
sufficient data. |
| In the Linux kernel, the following vulnerability has been resolved:
liveupdate: fix TOCTOU race in luo_session_retrieve()
Extend the scope of the rwsem_read lock in luo_session_retrieve() to
overlap with the acquisition of the session mutex. This prevents a
concurrent thread from releasing and freeing the session between the
lookup and the mutex lock. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix devx subscribe-event unwind NULL dereference
MLX5_IB_METHOD_DEVX_SUBSCRIBE_EVENT() links event_sub into sub_list
before initializing the fields used by the shared error path.
If eventfd_ctx_fdget() then fails, the unwind path dereferences
event_sub->ev_file in uverbs_uobject_put() and calls
subscribe_event_xa_dealloc() with an unset xa_key_level1.
subscribe_event_xa_alloc() creates the XA entry exactly once for a given
key_level1, on the first occurrence of that key. The unwind path must
therefore call subscribe_event_xa_dealloc() exactly once for it as well.
Enforce that by adding devx_key_in_sub_list() and calling
subscribe_event_xa_dealloc() only when the last matching pending entry is
being cleaned up. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_dualpi2: Do not call qdisc_tree_reduce_backlog during peek before restoring qlen
Whenever dualpi2 drops packets during peek, it calls
qdisc_tree_reduce_backlog. An issue arises because it calls
qdisc_tree_reduce_backlog before it reincrements the qlen. If qlen drops
to zero, but peek returns an skb, the parent's qlen_notify callback will be
executed even though dualpi2 still has 1 packet on the queue and, thus,
mistakenly deactivates the parent's class which leads to a null-ptr-deref:
