Security Vulnerabilities - CVEs Published In October 2024
In the Linux kernel, the following vulnerability has been resolved:
scsi: fnic: Move flush_work initialization out of if block
After commit 379a58caa199 ("scsi: fnic: Move fnic_fnic_flush_tx() to a
work queue"), it can happen that a work item is sent to an uninitialized
work queue. This may has the effect that the item being queued is never
actually queued, and any further actions depending on it will not
proceed.
The following warning is observed while the fnic driver is loaded:
kernel: WARNING: CPU: 11 PID: 0 at ../kernel/workqueue.c:1524 __queue_work+0x373/0x410

It has been observed that this may break the rediscovery of Fibre
Channel devices after a temporary fabric failure.
This patch fixes it by moving the work queue initialization out of
an if block in fnic_probe().

In the Linux kernel, the following vulnerability has been resolved:
scsi: wd33c93: Don't use stale scsi_pointer value
A regression was introduced with commit dbb2da557a6a ("scsi: wd33c93:
Move the SCSI pointer to private command data") which results in an oops
in wd33c93_intr(). That commit added the scsi_pointer variable and
initialized it from hostdata->connected. However, during selection,
hostdata->connected is not yet valid. Fix this by getting the current
scsi_pointer from hostdata->selecting.

The API Interface of the AWV (Audio, Web and Video Conferencing) component of Mitel MiCollab through 9.8 SP1 FP2 (9.8.1.201) could allow an unauthenticated attacker to conduct SQL injection due to insufficient sanitization of user input. A successful exploit could allow an attacker with knowledge of specific details to access non-sensitive user provisioning information and execute arbitrary SQL database commands.

A vulnerability in the AWV (Audio, Web, and Video) Conferencing component of Mitel MiCollab through 9.8 SP1 FP2 (9.8.1.201) could allow an unauthenticated attacker to perform unauthorized data-access attacks due to missing authentication mechanisms. A successful exploit could allow an attacker to access and delete sensitive information.

Learning with Texts (LWT) 2.0.3 is vulnerable to SQL Injection. This occurs when the application fails to properly sanitize user inputs, allowing attackers to manipulate SQL queries by injecting malicious SQL statements into URL parameters. By exploiting this vulnerability, an attacker could gain unauthorized access to the database, retrieve sensitive information, modify or delete data, and execute arbitrary commands.

In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: nixge: fix NULL dereference
In function nixge_hw_dma_bd_release() dereference of NULL pointer
priv->rx_bd_v is possible for the case of its allocation failure in
nixge_hw_dma_bd_init().
Move for() loop with priv->rx_bd_v dereference under the check for
its validity.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

In the Linux kernel, the following vulnerability has been resolved:
net/9p: Fix a potential socket leak in p9_socket_open
Both p9_fd_create_tcp() and p9_fd_create_unix() will call
p9_socket_open(). If the creation of p9_trans_fd fails,
p9_fd_create_tcp() and p9_fd_create_unix() will return an
error directly instead of releasing the cscoket, which will
result in a socket leak.
This patch adds sock_release() to fix the leak issue.

net: phy: fix null-ptr-deref while probe() failed
I got a null-ptr-deref report as following when doing fault injection test:

klist_remove() <- knode_driver is not added yet, cause null-ptr-deref
In phy_attach_direct(), after setting the 'dev->driver', probe() fails,
device_bind_driver() is not called, so the knode_driver->n_klist is not
set, then it causes null-ptr-deref in __device_release_driver() while
deleting device. Fix this by setting dev->driver to NULL in the error
path in phy_attach_direct().
