An Access of Uninitialized Pointer vulnerability in SIP Application Layer Gateway (ALG) of Juniper Networks Junos OS on SRX Series and MX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When specific valid SIP packets are received the PFE will crash and restart. This issue affects Juniper Networks Junos OS on SRX Series and MX Series: 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S2; 21.3 versions prior to 21.3R2-S2, 21.3R3; 21.4 versions prior to 21.4R1-S2, 21.4R2; 22.1 versions prior to 22.1R1-S1, 22.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 20.4R1. |
Memory corruption may occur during IO configuration processing when the IO port count is invalid. |
Win32k Elevation of Privilege Vulnerability |
A PHP Local File Inclusion (LFI) vulnerability in the J-Web component of Juniper Networks Junos OS may allow a low-privileged authenticated attacker to execute an untrusted PHP file. By chaining this vulnerability with other unspecified vulnerabilities, and by circumventing existing attack requirements, successful exploitation could lead to a complete system compromise. This issue affects Juniper Networks Junos OS: all versions prior to 19.1R3-S9; 19.2 versions prior to 19.2R3-S6; 19.3 versions prior to 19.3R3-S6; 19.4 versions prior to 19.4R2-S7, 19.4R3-S8; 20.1 versions prior to 20.1R3-S5; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S1; 21.3 versions prior to 21.3R2-S2, 21.3R3; 21.4 versions prior to 21.4R1-S2, 21.4R2-S1, 21.4R3; 22.1 versions prior to 22.1R1-S1, 22.1R2. |
Markdownify version 1.4.1 allows an external attacker to execute arbitrary code remotely on any client attempting to view a malicious markdown file through Markdownify. This is possible because the application has the "nodeIntegration" option enabled. |
In the Linux kernel, the following vulnerability has been resolved:
tee: amdtee: fix race condition in amdtee_open_session
There is a potential race condition in amdtee_open_session that may
lead to use-after-free. For instance, in amdtee_open_session() after
sess->sess_mask is set, and before setting:
sess->session_info[i] = session_info;
if amdtee_close_session() closes this same session, then 'sess' data
structure will be released, causing kernel panic when 'sess' is
accessed within amdtee_open_session().
The solution is to set the bit sess->sess_mask as the last step in
amdtee_open_session(). |
Access of uninitialized pointer in the Intel(R) Trace Analyzer and Collector before version 2021.5 may allow an authenticated user to potentially enable denial of service via local access. |
Windows Fax Service Remote Code Execution Vulnerability |
Secure Boot Security Feature Bypass Vulnerability |
Multiple uninitialized pointer vulnerabilities when parsing a specially crafted file in Esri ArcReader, ArcGIS Desktop, ArcGIS Engine 10.8.1 (and earlier) and ArcGIS Pro 2.7 (and earlier) allow an unauthenticated attacker to achieve arbitrary code execution in the context of the current user. |
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix the new buffer was not zeroed before writing
Before writing, if a buffer_head marked as new, its data must
be zeroed, otherwise uninitialized data in the page cache will
be written.
So this commit uses folio_zero_new_buffers() to zero the new
buffers before ->write_end(). |
In the Linux kernel, the following vulnerability has been resolved:
arm64: ptrace: fix partial SETREGSET for NT_ARM_TAGGED_ADDR_CTRL
Currently tagged_addr_ctrl_set() doesn't initialize the temporary 'ctrl'
variable, and a SETREGSET call with a length of zero will leave this
uninitialized. Consequently tagged_addr_ctrl_set() will consume an
arbitrary value, potentially leaking up to 64 bits of memory from the
kernel stack. The read is limited to a specific slot on the stack, and
the issue does not provide a write mechanism.
As set_tagged_addr_ctrl() only accepts values where bits [63:4] zero and
rejects other values, a partial SETREGSET attempt will randomly succeed
or fail depending on the value of the uninitialized value, and the
exposure is significantly limited.
Fix this by initializing the temporary value before copying the regset
from userspace, as for other regsets (e.g. NT_PRSTATUS, NT_PRFPREG,
NT_ARM_SYSTEM_CALL). In the case of a zero-length write, the existing
value of the tagged address ctrl will be retained.
The NT_ARM_TAGGED_ADDR_CTRL regset is only visible in the
user_aarch64_view used by a native AArch64 task to manipulate another
native AArch64 task. As get_tagged_addr_ctrl() only returns an error
value when called for a compat task, tagged_addr_ctrl_get() and
tagged_addr_ctrl_set() should never observe an error value from
get_tagged_addr_ctrl(). Add a WARN_ON_ONCE() to both to indicate that
such an error would be unexpected, and error handlnig is not missing in
either case. |
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Fix handling of partial GPU mapping of BOs
This commit fixes the bug in the handling of partial mapping of the
buffer objects to the GPU, which caused kernel warnings.
Panthor didn't correctly handle the case where the partial mapping
spanned multiple scatterlists and the mapping offset didn't point
to the 1st page of starting scatterlist. The offset variable was
not cleared after reaching the starting scatterlist.
Following warning messages were seen.

In the Linux kernel, the following vulnerability has been resolved:
riscv: Prevent a bad reference count on CPU nodes
When populating cache leaves we previously fetched the CPU device node
at the very beginning. But when ACPI is enabled we go through a
specific branch which returns early and does not call 'of_node_put' for
the node that was acquired.
Since we are not using a CPU device node for the ACPI code anyways, we
can simply move the initialization of it just passed the ACPI block, and
we are guaranteed to have an 'of_node_put' call for the acquired node.
This prevents a bad reference count of the CPU device node.
Moreover, the previous function did not check for errors when acquiring
the device node, so a return -ENOENT has been added for that case. |
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Additional check in ni_clear()
Checking of NTFS_FLAGS_LOG_REPLAYING added to prevent access to
uninitialized bitmap during replay process. |
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: altmode should keep reference to parent
The altmode device release refers to its parent device, but without keeping
a reference to it.
When registering the altmode, get a reference to the parent and put it in
the release function.

In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: dummy-hcd: Fix "task hung" problem
The syzbot fuzzer has been encountering "task hung" problems ever
since the dummy-hcd driver was changed to use hrtimers instead of
regular timers. It turns out that the problems are caused by a subtle
difference between the timer_pending() and hrtimer_active() APIs.
The changeover blindly replaced the first by the second. However,
timer_pending() returns True when the timer is queued but not when its
callback is running, whereas hrtimer_active() returns True when the
hrtimer is queued _or_ its callback is running. This difference
occasionally caused dummy_urb_enqueue() to think that the callback
routine had not yet started when in fact it was almost finished. As a
result the hrtimer was not restarted, which made it impossible for the
driver to dequeue later the URB that was just enqueued. This caused
usb_kill_urb() to hang, and things got worse from there.
Since hrtimers have no API for telling when they are queued and the
callback isn't running, the driver must keep track of this for itself.
That's what this patch does, adding a new "timer_pending" flag and
setting or clearing it at the appropriate times. |
In the Linux kernel, the following vulnerability has been resolved:
dm vdo: don't refer to dedupe_context after releasing it
Clear the dedupe_context pointer in a data_vio whenever ownership of
the context is lost, so that vdo can't examine it accidentally. |
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix uninitialized pointer free in add_inode_ref()
The add_inode_ref() function does not initialize the "name" struct when
it is declared. If any of the following calls to "read_one_inode()
returns NULL,
dir = read_one_inode(root, parent_objectid);
if (!dir) {
ret = -ENOENT;
goto out;
}
inode = read_one_inode(root, inode_objectid);
if (!inode) {
ret = -EIO;
goto out;
}
then "name.name" would be freed on "out" before being initialized.
out:
...
kfree(name.name);
This issue was reported by Coverity with CID 1526744. |
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix uninitialized pointer free on read_alloc_one_name() error
The function read_alloc_one_name() does not initialize the name field of
the passed fscrypt_str struct if kmalloc fails to allocate the
corresponding buffer. Thus, it is not guaranteed that
fscrypt_str.name is initialized when freeing it.
This is a follow-up to the linked patch that fixes the remaining
instances of the bug introduced by commit e43eec81c516 ("btrfs: use
struct qstr instead of name and namelen pairs"). |
