| In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: Fix potential kernel oops when probe fails
When probe of the sdio brcmfmac device fails for some reasons (i.e.
missing firmware), the sdiodev->bus is set to error instead of NULL, thus
the cleanup later in brcmf_sdio_remove() tries to free resources via
invalid bus pointer. This happens because sdiodev->bus is set 2 times:
first in brcmf_sdio_probe() and second time in brcmf_sdiod_probe(). Fix
this by chaning the brcmf_sdio_probe() function to return the error code
and set sdio->bus only there. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: bcm_vk: Fix possible null-pointer dereferences in bcm_vk_read()
In the function bcm_vk_read(), the pointer entry is checked, indicating
that it can be NULL. If entry is NULL and rc is set to -EMSGSIZE, the
following code may cause null-pointer dereferences:
struct vk_msg_blk tmp_msg = entry->to_h_msg[0];
set_msg_id(&tmp_msg, entry->usr_msg_id);
tmp_msg.size = entry->to_h_blks - 1;
To prevent these possible null-pointer dereferences, copy to_h_msg,
usr_msg_id, and to_h_blks from iter into temporary variables, and return
these temporary variables to the application instead of accessing them
through a potentially NULL entry. |
| A packet processing mechanism in Palo Alto Networks PAN-OS software enables a remote attacker to reboot hardware-based firewalls. Repeated attacks eventually cause the firewall to enter maintenance mode, which requires manual intervention to bring the firewall back online.
This affects the following hardware firewall models:
- PA-5400 Series firewalls
- PA-7000 Series firewalls |
| The Dial and LookupPort functions panic on Windows when provided with an input containing a NUL (0). |
| A null pointer dereference was addressed with improved input validation. This issue is fixed in iOS 26.5 and iPadOS 26.5, macOS Tahoe 26.5, tvOS 26.5. An attacker on the local network may be able to cause a denial-of-service. |
| Null pointer dereference in Windows Storport Miniport Driver allows an unauthorized attacker to deny service over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
clk: rs9: Reserve 8 struct clk_hw slots for for 9FGV0841
The 9FGV0841 has 8 outputs and registers 8 struct clk_hw, make sure
there are 8 slots for those newly registered clk_hw pointers, else
there is going to be out of bounds write when pointers 4..7 are set
into struct rs9_driver_data .clk_dif[4..7] field.
Since there are other structure members past this struct clk_hw
pointer array, writing to .clk_dif[4..7] fields corrupts both
the struct rs9_driver_data content and data around it, sometimes
without crashing the kernel. However, the kernel does surely
crash when the driver is unbound or during suspend.
Fix this, increase the struct clk_hw pointer array size to the
maximum output count of 9FGV0841, which is the biggest chip that
is supported by this driver. |
| In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, a mismatch between encoding lists in Oniguruma and mbfl leads to a NULL pointer dereference, resulting in a segmentation fault and denial of service. The vulnerability is exploitable when user-controlled input can influence the encoding passed to mb_regex_encoding(). |
| In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, when a SOAP server has a typemap configured, the decoding process contains a mistake which checks the wrong variable in case of missing value element. This leads to dereferences a NULL pointer, causing a segmentation fault. This allows a remote unauthenticated attacker to crash the PHP SOAP server process, resulting in denial of service. |
| The affected devices contain a null pointer dereference vulnerability while processing specially crafted IPv4 requests. This could allow an attacker to cause denial of service condition. A manual restart is required to recover the system. |
| Issue summary: During processing of a crafted CMS EnvelopedData message
with KeyTransportRecipientInfo a NULL pointer dereference can happen.
Impact summary: Applications that process attacker-controlled CMS data may
crash before authentication or cryptographic operations occur resulting in
Denial of Service.
When a CMS EnvelopedData message that uses KeyTransportRecipientInfo with
RSA-OAEP encryption is processed, the optional parameters field of
RSA-OAEP SourceFunc algorithm identifier is examined without checking
for its presence. This results in a NULL pointer dereference if the field
is missing.
Applications and services that call CMS_decrypt() on untrusted input
(e.g., S/MIME processing or CMS-based protocols) are vulnerable.
The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this
issue, as the affected code is outside the OpenSSL FIPS module boundary. |
| Issue summary: During processing of a crafted CMS EnvelopedData message

| Issue summary: When a delta CRL that contains a Delta CRL Indicator extension
is processed a NULL pointer dereference might happen if the required CRL
Number extension is missing.
Impact summary: A NULL pointer dereference can trigger a crash which
leads to a Denial of Service for an application.
When CRL processing and delta CRL processing is enabled during X.509
certificate verification, the delta CRL processing does not check
whether the CRL Number extension is NULL before dereferencing it.
When a malformed delta CRL file is being processed, this parameter
can be NULL, causing a NULL pointer dereference.
Exploiting this issue requires the X509_V_FLAG_USE_DELTAS flag to be enabled in
the verification context, the certificate being verified to contain a
freshestCRL extension or the base CRL to have the EXFLAG_FRESHEST flag set, and
an attacker to provide a malformed CRL to an application that processes it.
The vulnerability is limited to Denial of Service and cannot be escalated to
achieve code execution or memory disclosure. For that reason the issue was
assessed as Low severity according to our Security Policy.
The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,
as the affected code is outside the OpenSSL FIPS module boundary. |
| A vulnerability has been found in GNU Binutils 2.44 and classified as problematic. This vulnerability affects the function bfd_elf_get_str_section of the file bfd/elf.c of the component BFD Library. The manipulation leads to null pointer dereference. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The name of the patch is db856d41004301b3a56438efd957ef5cabb91530. It is recommended to apply a patch to fix this issue. |
| Issue summary: Processing a malformed PKCS#12 file can trigger a NULL pointer
dereference in the PKCS12_item_decrypt_d2i_ex() function.
Impact summary: A NULL pointer dereference can trigger a crash which leads to
Denial of Service for an application processing PKCS#12 files.
The PKCS12_item_decrypt_d2i_ex() function does not check whether the oct
parameter is NULL before dereferencing it. When called from
PKCS12_unpack_p7encdata() with a malformed PKCS#12 file, this parameter can
be NULL, causing a crash. The vulnerability is limited to Denial of Service
and cannot be escalated to achieve code execution or memory disclosure.
Exploiting this issue requires an attacker to provide a malformed PKCS#12 file
to an application that processes it. For that reason the issue was assessed as
Low severity according to our Security Policy.
The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,
as the PKCS#12 implementation is outside the OpenSSL FIPS module boundary.
OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are vulnerable to this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
pcmcia: Fix a NULL pointer dereference in __iodyn_find_io_region()
In __iodyn_find_io_region(), pcmcia_make_resource() is assigned to
res and used in pci_bus_alloc_resource(). There is a dereference of res
in pci_bus_alloc_resource(), which could lead to a NULL pointer
dereference on failure of pcmcia_make_resource().
Fix this bug by adding a check of res. |
| In the Linux kernel, the following vulnerability has been resolved:
media: venus: protect against spurious interrupts during probe
Make sure the interrupt handler is initialized before the interrupt is
registered.
If the IRQ is registered before hfi_create(), it's possible that an
interrupt fires before the handler setup is complete, leading to a NULL
dereference.
This error condition has been observed during system boot on Rb3Gen2. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Destroy KFD debugfs after destroy KFD wq
Since KFD proc content was moved to kernel debugfs, we can't destroy KFD
debugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq prior
to kfd_debugfs_fini to fix a kernel NULL pointer problem. It happens
when /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini but
kfd_process_destroy_wq calls kfd_debugfs_remove_process. This line
debugfs_remove_recursive(entry->proc_dentry);
tries to remove /sys/kernel/debug/kfd/proc/<pid> while
/sys/kernel/debug/kfd is already gone. It hangs the kernel by kernel
NULL pointer.

| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Avoid a NULL pointer dereference
[WHY]
Although unlikely drm_atomic_get_new_connector_state() or
drm_atomic_get_old_connector_state() can return NULL.
[HOW]
Check returns before dereference.

| In the Linux kernel, the following vulnerability has been resolved:
smb: server: split ksmbd_rdma_stop_listening() out of ksmbd_rdma_destroy()
We can't call destroy_workqueue(smb_direct_wq); before stop_sessions()!
Otherwise already existing connections try to use smb_direct_wq as
a NULL pointer. |
