CVSS v3.1 |
| The News Kit Addons For Elementor WordPress plugin through 1.4.7 does not perform capability or ownership checks before updating post metadata in one of its authenticated AJAX actions, allowing users with subscriber-level access and above to write arbitrary post meta, under attacker-chosen keys, to any post including those owned by other users. This can be used to overwrite protected core metadata and tamper with content created by higher-privileged users. |
| The Pixel Tag Manager for WooCommerce WordPress plugin before 2.2.3 does not perform a capability check in one of its AJAX actions, and exposes the nonce protecting it to any user able to access the admin dashboard, allowing users with a role as low as Contributor to overwrite the Pixel Tag Manager for WooCommerce WordPress plugin before 2.2.3's tracking configuration and have arbitrary JavaScript executed in the browsers of all visitors, including administrators. |
| The GeoDirectory WordPress plugin before 2.8.194 does not verify that a referenced attachment belongs to the listing being saved, allowing users with Subscriber-level access and above to modify the title, caption, moderation status and featured flag of images belonging to other users' listings, and to claim another user's image as their own featured image. |
| The GeoDirectory WordPress plugin before 2.8.194 does not validate a user-supplied image URL before using it as a local file path when saving a front-end listing, allowing users with Subscriber-level access and above to read files from outside the web root and to delete files on the server, limited to file names that carry an allowed media extension. A disclosed file is re-published at a public URL and its original is deleted as a side effect. |
| The GeoDirectory WordPress plugin before 2.8.194 does not perform status, ownership or password checks when loading listings for one of its unauthenticated AJAX handlers, allowing unauthenticated users to disclose the content of non-public (draft, pending and private) listings by supplying their IDs. |

| In the Linux kernel, the following vulnerability has been resolved:
drop_monitor: fix out-of-bounds write in reset_per_cpu_data()
In reset_per_cpu_data(), al is computed as:
al = sizeof(struct net_dm_alert_msg);
al += dm_hit_limit * sizeof(struct net_dm_drop_point);
al += sizeof(struct nlattr);
skb = genlmsg_new(al, GFP_KERNEL);
...
nla = nla_reserve(skb, NLA_UNSPEC, sizeof(struct net_dm_alert_msg));
...
msg = nla_data(nla);
memset(msg, 0, al);
Because al includes sizeof(struct nlattr) (the 4-byte attribute header),
genlmsg_new() allocates al bytes of tailroom starting at nla.
However, msg points to nla_data(nla), which is located
sizeof(struct nlattr) bytes past nla. Calling memset(msg, 0, al)
therefore writes al bytes starting from msg, exceeding the allocated
buffer by sizeof(struct nlattr) (4 bytes) and corrupting
skb_shared_info.
Fix this by letting al represent only the payload length, allocating
the skb with genlmsg_new(nla_total_size(al), GFP_KERNEL), and zeroing
al bytes from msg. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: alps: fix use-after-free on input2 registration failure
alps_input_configured() stores data->input2 before calling
input_register_device(). If registration fails, input_free_device()
frees the input device but data->input2 still points to the freed memory.
alps_input_configured() calls hid_hw_open() before allocating input2, so
URBs are already active and raw_event can fire during the failure window.
A U1_SP_ABSOLUTE_REPORT_ID report arriving then causes u1_raw_event()
to dereference the freed data->input2 -> use-after-free.
Fix by only storing input2 into drvdata after successful registration
and adding a NULL guard in the raw_event path. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: fs/xattr: don't assume the inode is locked in path_unlink/path_rmdir
bpf_lsm_has_d_inode_locked() makes the verifier rewrite
bpf_[set|remove]_dentry_xattr() to the _locked variants, which assume
that the caller already holds the inode's i_rwsem. The path_unlink and
path_rmdir hooks are listed, but security_path_unlink() and
security_path_rmdir() run before vfs_unlink()/vfs_rmdir() take the
victim inode's i_rwsem, so a sleepable BPF LSM program attached to
either hook mutates the victim's xattrs without the lock held.
Drop the two path hooks from d_inode_locked_hooks so that the verifier
keeps the locking bpf_[set|remove]_dentry_xattr() variants, which take
the lock themselves. |
| In the Linux kernel, the following vulnerability has been resolved:
amt: send the relay's General Query directly from the receive path
An skb queued in a qdisc can outlive the tunnel it references
through a raw pointer in skb->cb. For example, with igmp_qrv set
to 1 on the relay a tunnel lives for 135s, so a netem delay of
180s on the amt device outlives it; when the tunnel expires and is
freed, the subsequent dequeue triggers a use-after-free in
amt_dev_xmit().
BUG: KASAN: slab-use-after-free in amt_dev_xmit+0x2763/0x2e20

netem_dequeue+0x333/0xc50
net_tx_action+0x35c/0xa60
amt_send_igmp_gq() and amt_send_mld_gq() are only called from
amt_request_handler(), inside the rcu_read_lock_bh() section of
amt_rcv(). amt_request_handler() already has the tunnel the query is
for: it found or created it inside that section. Queuing the query with
dev_queue_xmit() only leads back into amt_dev_xmit(), which strips the
Ethernet header and calls amt_send_membership_query() for that tunnel.
Make that call directly from the two senders instead, the same way
amt_send_advertisement() transmits from the receive path. The query
never waits in a qdisc, the tunnel is only dereferenced inside the
RCU section that found or created it, and nothing is stored in
skb->cb, so no lookup or refcount is needed. Remove the query branch
of amt_dev_xmit(), amt_skb_cb() and struct amt_skb_cb, which have no
users left.
Behaviour changes:
- The relay's own General Queries no longer pass through the amt
device's egress path: its qdisc, tc egress (clsact/tcx), the
netfilter egress hook and packet taps. They are still visible as
UDP on the underlay.
- A query that is sent successfully is no longer counted as
tx_dropped. The old query branch left through the unlock label,
which counted every sent query as dropped.
- A query that reaches amt_dev_xmit() on a relay from elsewhere,
such as a userspace querier, is now dropped at the IGMP/MLD type
switch. Before, it trusted whatever skb->cb held, and a NULL
tunnel hit the WARN_ON(1). |
| In the Linux kernel, the following vulnerability has been resolved:
namespace: never expire a locked mount
Locked mounts are special. They protect the underlying files and
directories from being revealed. do_umount() refuses to unmount locked
mounts but shrink_submounts() doesn't.
A shrinkable mount can become locked once the owner of a user namespace
puts it beneath a locked mount with MOVE_MOUNT_BENEATH. The locked
property now moves to the mount at the bottom making it possible to
unmount the top mount.
So umount() of an unlocked ancestor now expires the bottom mount first
and the covered directory is revealed:
move_mount(c -> x/hidden, MOVE_MOUNT_BENEATH) = 0
the cover after the lock moved: umount2(x/hidden) = 0
the holder of the lock: umount2(x/hidden) = EINVAL
the root of the copy, busy: umount2(x) = EBUSY
reads x/hidden/secret: "covered-by-root"
So leave a locked mount alone as it dies together with its parent. A
plain umount() of an unlocked mount with a locked one below it is EBUSY
from now on. It's the same for any other locked child. A lazy umount
still takes the whole tree.
mark_mounts_for_expiry() never sees a locked mount. lock_mnt_tree()
leaves a mount on an expiry list alone and nothing else puts a locked
one on such a list. Add an assert for this. |
| The GeoDirectory WordPress plugin before 2.8.194 does not correctly verify ownership of listings submitted by logged-out users before allowing them to be edited, allowing unauthenticated attackers to modify, unpublish, attach images to, or reassign any guest-submitted listing when guest posting is enabled. |

| Use after free in Microsoft Windows Search Component allows an authorized attacker to elevate privileges locally. |
| A flaw was found in Nautilus. When a removable drive or disk image is unmounted or ejected, Nautilus prompts the user to empty the trash without verifying whether the trash directory paths are symbolic links. An attacker can exploit this flaw by tricking a user into mounting a crafted storage volume and confirming the prompt to empty the trash, leading to the arbitrary deletion of files accessible to that user. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: libiscsi_tcp: Check the data direction of a Data-In PDU
The Data-In branch of iscsi_tcp_hdr_dissect() resolves the ITT to a task
and copies the PDU's data segment into that command's scatterlist without
asking whether the command was reading. iscsi_tcp_r2t_rsp() in the same
file does ask, and rejects an R2T for a command that is not DMA_TO_DEVICE.
A target that answers a WRITE command's ITT with a Data-In therefore has
the initiator write target-supplied bytes into the pages that write was
about to send. Those are the caller's own pinned pages for an O_DIRECT
write, and page cache pages for a buffered one.
Observed against a test target that emits one 512-byte Data-In naming a 128
KB write's ITT, after the R2T for that write. With O_DIRECT the caller's
buffer ends up holding 512 bytes of the target's data while pwrite()
returns 131072. Buffered is quieter: pwrite() and fsync() both succeed,
nothing is logged, and reading those blocks back returns the target's bytes
out of the page cache without a command going on the wire.
Check the direction before using the scatterlist, the way the R2T path
already does. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Skip unsettled links in link iterator
bpf_link_prime() inserts a link into link_idr before anon_inode_getfile()
succeeds and before bpf_link_settle() publishes the ID in link->id.
bpf_link_by_id() treats such an ID-zero link as unsettled, but the link
iterator takes a reference without this check.
If anon_inode_getfile() then fails, the creator removes the ID and frees
its still-private link directly. The iterator is left with a dangling
reference and its next bpf_link_put() accesses freed memory.
Treat ID-zero entries as transient in bpf_link_get_curr_or_next(), just as
bpf_link_by_id() does.

net/mlx5e: fix swapped IPv6 IPsec policy masks
IPv6 XFRM policies may use different source and destination prefix
lengths. mlx5e_ipsec_policy_mask() builds the corresponding masks
independently, but setup_fte_addr6() installs each mask in the opposite
address field.
When the prefix lengths differ, this makes the source match use the
destination prefix and the destination match use the source prefix. The
resulting hardware rule can both miss traffic covered by the policy and
match traffic outside it.
Install each mask in its corresponding match field. |

drm/nouveau/uvmm: fix UAF in nouveau_uvmm_sm when BO is in TTM_PL_SYSTEM
nouveau_uvmm_sm() calls op_map(), which passes bo->resource through
nouveau_mem() to nouveau_uvma_map(). nouveau_uvmm_vmm_map() then reads
mem->mem.type.
But this is only valid when bo->resource is backed by struct nouveau_mem,
as is the case for VRAM and TT resources. If the BO is left in
TTM_PL_SYSTEM, bo->resource is only a struct ttm_resource. Treating it
as struct nouveau_mem makes the mem->mem.type read past the end of the
resource, causing a KASAN: slab-use-after-free Read in nouveau_uvmm_sm
