| In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Avoid using sk_socket after free when sending
The sk->sk_socket is not locked or referenced in backlog thread, and
during the call to skb_send_sock(), there is a race condition with
the release of sk_socket. All types of sockets(tcp/udp/unix/vsock)
will be affected.
Race conditions:
'''
CPU0 CPU1
backlog::skb_send_sock
sendmsg_unlocked
sock_sendmsg
sock_sendmsg_nosec
close(fd):
...
ops->release() -> sock_map_close()
sk_socket->ops = NULL
free(socket)
sock->ops->sendmsg
^
panic here
'''
The ref of psock become 0 after sock_map_close() executed.
'''
void sock_map_close()
{
...
if (likely(psock)) {
...
// !! here we remove psock and the ref of psock become 0
sock_map_remove_links(sk, psock)
psock = sk_psock_get(sk);
if (unlikely(!psock))
goto no_psock; <=== Control jumps here via goto
...
cancel_delayed_work_sync(&psock->work); <=== not executed
sk_psock_put(sk, psock);
...
}
'''
Based on the fact that we already wait for the workqueue to finish in
sock_map_close() if psock is held, we simply increase the psock
reference count to avoid race conditions.
With this patch, if the backlog thread is running, sock_map_close() will
wait for the backlog thread to complete and cancel all pending work.
If no backlog running, any pending work that hasn't started by then will
fail when invoked by sk_psock_get(), as the psock reference count have
been zeroed, and sk_psock_drop() will cancel all jobs via
cancel_delayed_work_sync().
In summary, we require synchronization to coordinate the backlog thread
and close() thread.
The panic I catched:

net: usb: aqc111: fix error handling of usbnet read calls
Syzkaller, courtesy of syzbot, identified an error (see report [1]) in
aqc111 driver, caused by incomplete sanitation of usb read calls'
results. This problem is quite similar to the one fixed in commit
920a9fa27e78 ("net: asix: add proper error handling of usb read errors").
For instance, usbnet_read_cmd() may read fewer than 'size' bytes,
even if the caller expected the full amount, and aqc111_read_cmd()
will not check its result properly. As [1] shows, this may lead
to MAC address in aqc111_bind() being only partly initialized,
triggering KMSAN warnings.
Fix the issue by verifying that the number of bytes read is
as expected and not less.

| In the Linux kernel, the following vulnerability has been resolved:
RDMA/cma: Fix hang when cma_netevent_callback fails to queue_work
The cited commit fixed a crash when cma_netevent_callback was called for
a cma_id while work on that id from a previous call had not yet started.
The work item was re-initialized in the second call, which corrupted the
work item currently in the work queue.
However, it left a problem when queue_work fails (because the item is
still pending in the work queue from a previous call). In this case,
cma_id_put (which is called in the work handler) is therefore not
called. This results in a userspace process hang (zombie process).
Fix this by calling cma_id_put() if queue_work fails. |
| A stored cross-site scripting (XSS) vulnerability in the PwdGrp.cgi endpoint of AVTECH SECURITY Corporation DGM1104 FullImg-1015-1004-1006-1003 allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the username field. |
| Abacre Restaurant Point of Sale (POS) up to 15.0.0.1656 are vulnerable to Cleartext Storage of Sensitive Information in Memory. The application leaves valid device-bound license keys in process memory during an activation attempt. |
| An Improper Input Validation vulnerability exists in the user websocket handler of MAAS. An authenticated, unprivileged attacker can intercept a user.update websocket request and inject the is_superuser property set to true. The server improperly validates this input, allowing the attacker to self-promote to an administrator role. This results in full administrative control over the MAAS deployment. |
| A local privilege escalation vulnerability exists in the InstallationHelper service included with Plugin Alliance Installation Manager v1.4.0 for macOS. The service accepts unauthenticated XPC connections and executes input via system(), which may allow a local user to execute arbitrary commands with root privileges. |
| A local privilege escalation vulnerability exists in the Plugin Alliance InstallationHelper service included with Plugin Alliance Installation Manager v1.4.0 on macOS. Due to the absence of a hardened runtime and a __RESTRICT segment, a local user may exploit the DYLD_INSERT_LIBRARIES environment variable to inject a dynamic library, potentially resulting in code execution with elevated privileges. |
| Aquarius Desktop 3.0.069 for macOS stores user authentication credentials in the local file ~/Library/Application Support/Aquarius/aquarius.settings using a weak obfuscation scheme. The password is "encrypted" through predictable byte-substitution that can be trivially reversed, allowing immediate recovery of the plaintext value. Any attacker who can read this settings file can fully compromise the victim's Aquarius account by importing the stolen configuration into their own client or login through the vendor website. This results in complete account takeover, unauthorized access to cloud-synchronized data, and the ability to perform authenticated actions as the user. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: bcm: rpi: Add NULL check in raspberrypi_clk_register()
devm_kasprintf() returns NULL when memory allocation fails. Currently,
raspberrypi_clk_register() does not check for this case, which results
in a NULL pointer dereference.
Add NULL check after devm_kasprintf() to prevent this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
hisi_acc_vfio_pci: fix XQE dma address error
The dma addresses of EQE and AEQE are wrong after migration and
results in guest kernel-mode encryption services failure.
Comparing the definition of hardware registers, we found that
there was an error when the data read from the register was
combined into an address. Therefore, the address combination
sequence needs to be corrected.
Even after fixing the above problem, we still have an issue
where the Guest from an old kernel can get migrated to
new kernel and may result in wrong data.
In order to ensure that the address is correct after migration,
if an old magic number is detected, the dma address needs to be
updated. |
| MaxKB is an open-source AI assistant for enterprise. Versions 2.3.1 and below have improper file permissions which allow attackers to overwrite the built-in dynamic linker and other critical files, potentially resulting in privilege escalation. This issue is fixed in version 2.4.0. |
| The Aquarius HelperTool (1.0.003) privileged XPC service on macOS contains multiple flaws that allow local privilege escalation. The service accepts XPC connections from any local process without validating the client's identity, and its authorization logic incorrectly calls AuthorizationCopyRights with a NULL reference, causing all authorization checks to succeed. The executeCommand:authorization:withReply: method then interpolates attacker-controlled input into NSTask and executes it with root privileges. A local attacker can exploit these weaknesses to run arbitrary commands as root, create persistent backdoors, or obtain a fully interactive root shell. |
| MaxKB is an open-source AI assistant for enterprise. In versions 2.3.1 and below, the tool module allows an attacker to escape the sandbox environment and escalate privileges under certain concurrent conditions. This issue is fixed in version 2.4.0. |
| Aquarius Desktop 3.0.069 for macOS contains an insecure file handling vulnerability in its support data archive generation feature. The application follows symbolic links placed inside the ~/Library/Logs/Aquarius directory and treats them as regular files. When building the support ZIP, Aquarius recursively enumerates logs using a JUCE directory iterator configured to follow symlinks, and later writes file data without validating whether the target is a symbolic link. A local attacker can exploit this behavior by planting symlinks to arbitrary filesystem locations, resulting in unauthorized disclosure or modification of arbitrary files. When chained with the associated HelperTool privilege escalation issue, root-owned files may also be exposed. |
