CVSS v3.1 |
| An issue was discovered on Marbella KR8s Dashcam FF 2.0.8 devices. Once access is gained either by default, common, or cracked passwords, the video recordings (containing sensitive routes, conversations, and footage) are open for downloading by creating a socket to command port 7777, and then downloading video via port 7778 and audio via port 7779. |
| A type confusion vulnerability in lib/NSSAuthenticator.php in ZendTo before v5.04-7 allows remote attackers to bypass authentication for users with passwords stored as MD5 hashes that can be interpreted as numbers. A solution requires moving from MD5 to bcrypt. |
| SoftEtherVPN is a an open-source cross-platform multi-protocol VPN Program. Versions 5.02.5184 to 5.02.5187 are vulnerable to NULL dereference in `DeleteIPv6DefaultRouterInRA` called by `StorePacket`. Before dereferencing, `DeleteIPv6DefaultRouterInRA` does not account for `ParsePacket` returning NULL, resulting in the program crashing. A patched version does not exist at this time. |
| NVIDIA Isaac-GR00T for all platforms contains a vulnerability in a Python component, where an attacker could cause a code injection issue. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering. |
| A path traversal vulnerability exists in the file dropoff functionality
of ZendTo versions 6.15-7 and prior. This could allow a remote, authenticated attacker to retrieve the files of other ZendTo users, retrieve files on the host
system, or cause a denial of service. |
| Delta Electronics COMMGR v1 and v2 uses insufficiently randomized values to generate session IDs (CWE-338). An attacker could easily brute force a session ID and load and execute arbitrary code. |
| A vulnerability, which was classified as problematic, was found in mirweiye Seven Bears Library CMS 2023. This affects an unknown part of the component Background Management Page. The manipulation leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. |
| The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to Authentication Bypass in versions 1.9.1 to 7.5.2. This is due to handel_ajax_req() function not having proper restrictions on the change_user_meta functionality that makes it possible to set a OTP code and subsequently log in with that OTP code. This makes it possible for unauthenticated attackers to login as other users on the site, including administrators. |
| The WPshop 2 – E-Commerce plugin for WordPress is vulnerable to privilege escalation via account takeover in versions 2.0.0 to 2.6.0. This is due to the plugin not properly validating a user's identity prior to updating their details like email & password through the update() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account. |
| The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the handel_ajax_req() function in versions 1.9.1 to 7.5.2. This makes it possible for unauthenticated attackers to update arbitrary user's metadata which can be leveraged to block an administrator from accessing their site when wp_capabilities is set to 0. |
| The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to unauthorized access of data via its publicly exposed reset-password endpoint. The plugin looks up the 'valid_email' value based solely on a supplied username parameter, without verifying that the requester is associated with that user account. This allows unauthenticated attackers to enumerate email addresses for any user, including administrators. |
| In the Linux kernel, the following vulnerability has been resolved:
gve: Implement gettimex64 with -EOPNOTSUPP
gve implemented a ptp_clock for sole use of do_aux_work at this time.
ptp_clock_gettime() and ptp_sys_offset() assume every ptp_clock has
implemented either gettimex64 or gettime64. Stub gettimex64 and return
-EOPNOTSUPP to prevent NULL dereferencing. |

virtio-net: fix received length check in big packets
Since commit 4959aebba8c0 ("virtio-net: use mtu size as buffer length
for big packets"), when guest gso is off, the allocated size for big
packets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but depends on
negotiated MTU. The number of allocated frags for big packets is stored
in vi->big_packets_num_skbfrags.
Because the host announced buffer length can be malicious (e.g. the host
vhost_net driver's get_rx_bufs is modified to announce incorrect
length), we need a check in virtio_net receive path. Currently, the
check is not adapted to the new change which can lead to NULL page
pointer dereference in the below while loop when receiving length that
is larger than the allocated one.
This commit fixes the received length check corresponding to the new
change. |
| In the Linux kernel, the following vulnerability has been resolved:
iommufd: Don't overflow during division for dirty tracking
If pgshift is 63 then BITS_PER_TYPE(*bitmap->bitmap) * pgsize will overflow
to 0 and this triggers divide by 0.
In this case the index should just be 0, so reorganize things to divide
by shift and avoid hitting any overflows. |
| In the Linux kernel, the following vulnerability has been resolved:
net: bridge: fix use-after-free due to MST port state bypass
syzbot reported[1] a use-after-free when deleting an expired fdb. It is
due to a race condition between learning still happening and a port being
deleted, after all its fdbs have been flushed. The port's state has been
toggled to disabled so no learning should happen at that time, but if we
have MST enabled, it will bypass the port's state, that together with VLAN
filtering disabled can lead to fdb learning at a time when it shouldn't
happen while the port is being deleted. VLAN filtering must be disabled
because we flush the port VLANs when it's being deleted which will stop
learning. This fix adds a check for the port's vlan group which is
initialized to NULL when the port is getting deleted, that avoids the port
state bypass. When MST is enabled there would be a minimal new overhead
in the fast-path because the port's vlan group pointer is cache-hot.

Bluetooth: hci_event: validate skb length for unknown CC opcode
In hci_cmd_complete_evt(), if the command complete event has an unknown
opcode, we assume the first byte of the remaining skb->data contains the
return status. However, parameter data has previously been pulled in
hci_event_func(), which may leave the skb empty. If so, using skb->data[0]
for the return status uses un-init memory.
The fix is to check skb->len before using skb->data. |

btrfs: ensure no dirty metadata is written back for an fs with errors
[BUG]
During development of a minor feature (make sure all btrfs_bio::end_io()
is called in task context), I noticed a crash in generic/388, where
metadata writes triggered new works after btrfs_stop_all_workers().
It turns out that it can even happen without any code modification, just
using RAID5 for metadata and the same workload from generic/388 is going
to trigger the use-after-free.
[CAUSE]
If btrfs hits an error, the fs is marked as error, no new
transaction is allowed thus metadata is in a frozen state.
But there are some metadata modifications before that error, and they are
still in the btree inode page cache.
Since there will be no real transaction commit, all those dirty folios
are just kept as is in the page cache, and they can not be invalidated
by invalidate_inode_pages2() call inside close_ctree(), because they are
dirty.
And finally after btrfs_stop_all_workers(), we call iput() on btree
inode, which triggers writeback of those dirty metadata.
And if the fs is using RAID56 metadata, this will trigger RMW and queue
new works into rmw_workers, which is already stopped, causing warning
from queue_work() and use-after-free.
[FIX]
Add a special handling for write_one_eb(), that if the fs is already in
an error state, immediately mark the bbio as failure, instead of really
submitting them.
Then during close_ctree(), iput() will just discard all those dirty
tree blocks without really writing them back, thus no more new jobs for
already stopped-and-freed workqueues.
The extra discard in write_one_eb() also acts as an extra safenet.
E.g. the transaction abort is triggered by some extent/free space
tree corruptions, and since extent/free space tree is already corrupted
some tree blocks may be allocated where they shouldn't be (overwriting
existing tree blocks). In that case writing them back will further
corrupting the fs. |

9p/trans_fd: p9_fd_request: kick rx thread if EPOLLIN
p9_read_work() doesn't set Rworksched and doesn't do schedule_work(m->rq)
if list_empty(&m->req_list).
However, if the pipe is full, we need to read more data and this used to
work prior to commit aaec5a95d59615 ("pipe_read: don't wake up the writer
if the pipe is still full").
p9_read_work() does p9_fd_read() -> ... -> anon_pipe_read() which (before
the commit above) triggered the unnecessary wakeup. This wakeup calls
p9_pollwake() which kicks p9_poll_workfn() -> p9_poll_mux(), p9_poll_mux()
will notice EPOLLIN and schedule_work(&m->rq).
This no longer happens after the optimization above, change p9_fd_request()
to use p9_poll_mux() instead of only checking for EPOLLOUT. |
| In the Linux kernel, the following vulnerability has been resolved:
exfat: validate cluster allocation bits of the allocation bitmap
syzbot created an exfat image with cluster bits not set for the allocation
bitmap. exfat-fs reads and uses the allocation bitmap without checking
this. The problem is that if the start cluster of the allocation bitmap
is 6, cluster 6 can be allocated when creating a directory with mkdir.
exfat zeros out this cluster in exfat_mkdir, which can delete existing
entries. This can reallocate the allocated entries. In addition,
the allocation bitmap is also zeroed out, so cluster 6 can be reallocated.
This patch adds exfat_test_bitmap_range to validate that clusters used for
the allocation bitmap are correctly marked as in-use. |

Bluetooth: bcsp: receive data only if registered
Currently, bcsp_recv() can be called even when the BCSP protocol has not
been registered. This leads to a NULL pointer dereference, as shown in
the following stack trace:
