CVSS v3.1 |
| A security vulnerability has been detected in code-projects Student Crud Operation 3.3. Affected is an unknown function of the file delete.php. The manipulation of the argument ID leads to sql injection. The attack is possible to be carried out remotely. The exploit has been disclosed publicly and may be used. |
| A weakness has been identified in code-projects Online Course Registration 1.0. This impacts an unknown function of the file /admin/edit-course.php. Executing manipulation of the argument coursecode can lead to sql injection. The attack can be executed remotely. The exploit has been made available to the public and could be exploited. |
| A security flaw has been discovered in Jinher OA up to 2.0. This affects an unknown function of the file /c6/Jhsoft.Web.module/eformaspx/WebDesign.aspx/?type=SystemUserInfo&style=1. Performing manipulation results in xml external entity reference. Remote exploitation of the attack is possible. The exploit has been released to the public and may be exploited. |
| A flaw has been found in D-Link DI-7100G C1 up to 20250928. This vulnerability affects the function sub_4C0990 of the file /webchat/login.cgi of the component jhttpd. Executing manipulation of the argument openid can lead to buffer overflow. It is possible to launch the attack remotely. The exploit has been published and may be used. |
| IBM Standards Processing Engine 10.0.1.10 could allow a remote attacker to execute arbitrary code on the system, caused by an unsafe java deserialization. By sending specially crafted input, an attacker could exploit this vulnerability to execute arbitrary code on the system. |
| A potential security vulnerability has been identified in HP Sure Start’s protection of the Intel Flash Descriptor in certain HP PC products, which might allow security bypass, arbitrary code execution, loss of integrity or confidentiality, or denial of service. HP is releasing BIOS updates to mitigate the potential vulnerability. |
| ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a ProxyCommand is used. |
| The WP Reset plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.05 via the WF_Licensing::log() method when debugging is enabled (default). This makes it possible for unauthenticated attackers to extract sensitive license key and site data. |
| The Admin and Customer Messages After Order for WooCommerce: OrderConvo WordPress plugin before 14 does not validate the path of files to be downloaded, which could allow unauthenticated attacker to read/download arbitrary files via a path traversal attack |

The reason is that if priv->hdl.error is set, ov772x_probe() jumps to the
error_mutex_destroy without doing v4l2_ctrl_handler_free(), and all
resources allocated in v4l2_ctrl_handler_init() and v4l2_ctrl_new_std()
are leaked. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: microchip: fix potential UAF in auxdev release callback
Similar to commit 1c11289b34ab ("peci: cpu: Fix use-after-free in
adev_release()"), the auxiliary device is not torn down in the correct
order. If auxiliary_device_add() fails, the release callback will be
called twice, resulting in a UAF. Due to timing, the auxdev code in this
driver "took inspiration" from the aforementioned commit, and thus its
bugs too!
Moving auxiliary_device_uninit() to the unregister callback instead
avoids the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: conntrack: fix wrong ct->timeout value
(struct nf_conn)->timeout is an interval before the conntrack
confirmed. After confirmed, it becomes a timestamp.
It is observed that timeout of an unconfirmed conntrack:
- Set by calling ctnetlink_change_timeout(). As a result,
`nfct_time_stamp` was wrongly added to `ct->timeout` twice.
- Get by calling ctnetlink_dump_timeout(). As a result,
`nfct_time_stamp` was wrongly subtracted.

Pablo appends:
Update ctnetlink to set up the timeout _after_ the IPS_CONFIRMED flag is
set on, otherwise conntrack creation via ctnetlink breaks.

introduction of the nfnetlink_queue conntrack support, select a

platform/x86: dell-sysman: Fix reference leak
If a duplicate attribute is found using kset_find_obj(),
a reference to that attribute is returned. This means
that we need to dispose it accordingly. Use kobject_put()
to dispose the duplicate attribute in such a case.

| In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix possible data races in gfs2_show_options()
Some fields such as gt_logd_secs of the struct gfs2_tune are accessed
without holding the lock gt_spin in gfs2_show_options():
val = sdp->sd_tune.gt_logd_secs;
if (val != 30)
seq_printf(s, ",commit=%d", val);
And thus can cause data races when gfs2_show_options() and other functions
such as gfs2_reconfigure() are concurrently executed:
spin_lock(>->gt_spin);
gt->gt_logd_secs = newargs->ar_commit;
To fix these possible data races, the lock sdp->sd_tune.gt_spin is
acquired before accessing the fields of gfs2_tune and released after these
accesses.
Further changes by Andreas:
- Don't hold the spin lock over the seq_printf operations. |
| In the Linux kernel, the following vulnerability has been resolved:
memcontrol: ensure memcg acquired by id is properly set up
In the eviction recency check, we attempt to retrieve the memcg to which
the folio belonged when it was evicted, by the memcg id stored in the
shadow entry. However, there is a chance that the retrieved memcg is not
the original memcg that has been killed, but a new one which happens to
have the same id.
This is a somewhat unfortunate, but acceptable and rare inaccuracy in the
heuristics. However, if we retrieve this new memcg between its allocation
and when it is properly attached to the memcg hierarchy, we could run into
the following NULL pointer exception during the memcg hierarchy traversal
done in mem_cgroup_get_nr_swap_pages():

| In the Linux kernel, the following vulnerability has been resolved:
btrfs: reject invalid reloc tree root keys with stack dump
[BUG]
Syzbot reported a crash that an ASSERT() got triggered inside
prepare_to_merge().
That ASSERT() makes sure the reloc tree is properly pointed back by its
subvolume tree.
[CAUSE]
After more debugging output, it turns out we had an invalid reloc tree:
BTRFS error (device loop1): reloc tree mismatch, root 8 has no reloc root, expect reloc root key (-8, 132, 8) gen 17
Note the above root key is (TREE_RELOC_OBJECTID, ROOT_ITEM,
QUOTA_TREE_OBJECTID), meaning it's a reloc tree for quota tree.
But reloc trees can only exist for subvolumes, as for non-subvolume
trees, we just COW the involved tree block, no need to create a reloc
tree since those tree blocks won't be shared with other trees.
Only subvolumes tree can share tree blocks with other trees (thus they
have BTRFS_ROOT_SHAREABLE flag).
Thus this new debug output proves my previous assumption that corrupted
on-disk data can trigger that ASSERT().
[FIX]
Besides the dedicated fix and the graceful exit, also let tree-checker to
check such root keys, to make sure reloc trees can only exist for subvolumes. |

tipc: fix a null-ptr-deref in tipc_topsrv_accept
syzbot found a crash in tipc_topsrv_accept:
KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f]

It was caused by srv->listener that might be set to null by
tipc_topsrv_stop() in net .exit whereas it's still used in
tipc_topsrv_accept() worker.
srv->listener is protected by srv->idr_lock in tipc_topsrv_stop(), so add
a check for srv->listener under srv->idr_lock in tipc_topsrv_accept() to
avoid the null-ptr-deref. To ensure the lsock is not released during the
tipc_topsrv_accept(), move sock_release() after tipc_topsrv_work_stop()
where it's waiting until the tipc_topsrv_accept worker to be done.
Note that sk_callback_lock is used to protect sk->sk_user_data instead of
srv->listener, and it should check srv in tipc_topsrv_listener_data_ready()
instead. This also ensures that no more tipc_topsrv_accept worker will be
started after tipc_conn_close() is called in tipc_topsrv_stop() where it
sets sk->sk_user_data to null. |
