| Null pointer dereference for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts. |
| A NULL
pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing SOAP action requests. A specially crafted SOAP action request containing unexpected XML content may cause the UPnP daemon to terminate unexpectedly.
Successful exploitation may result in a denial-of-service condition affecting UPnP functionality until the service is restarted or the device is rebooted. |
| A NULL
pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing
SOAP state variable query requests. A specially crafted SOAP query may trigger
unexpected termination or instability of the process hosting the UPnP service.
Successful
exploitation may result in a denial-of-service condition affecting UPnP
discovery, state query, or related management functionality until the affected
process is restarted or the device is rebooted. |

The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts. |
| A vulnerability was determined in FLVMeta up to 1.2.2. Affected by this vulnerability is the function amf_object_get of the file src/amf.c of the component AMF Object Parsing. This manipulation causes null pointer dereference. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. Patch name: 52642f7dfb76ec7334016622dde60b1ae963d79b. To fix this issue, it is recommended to deploy a patch. The project maintainer doubts the security impact: "While I acknowledged the bugs and provided fixes, I have yet to see any way to exploit these alleged vulnerabilities." |
| A null pointer dereference vulnerability exists in the server-side session management logic of ccoap 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5. The issue is caused by a race condition between the request dispatch thread and the session cleanup thread when accessing shared session list nodes without proper synchronization. |
| A NULL pointer dereference in the get_min_buffer_size function (/libswscale/slice.c) of FFmpeg N-122528-gdd2976b9e1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted video file. |
| A NULL pointer dereference in the UDMC registration handler component of free5gc v4.0.1 allows attackers to cause a Denial of Service (DoS) via supplying crafted payload. |
| A NULL pointer dereference in the CDR processing path of free5gc v4.0.1 allows attackers to cause a Denial of Service (DoS) via supplying crafted payload. |
| X.509IF protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service |
| In Stomper 5e2741e when a client sends a SEND frame missing the destination header field, the server triggers a null pointer dereference (or access to invalid memory) while processing the frame, causing the process to crash. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI: dwc: Avoid dwc_pcie_rasdes_debugfs_deinit() NULL dereference when no RAS DES capability
dwc_pcie_rasdes_debugfs_init() returns success when the controller has no
RAS DES capability, leaving pci->debugfs->rasdes_info unset. The common
debugfs teardown path still calls dwc_pcie_rasdes_debugfs_deinit(), which
dereferences rasdes_info unconditionally.
Return early when no RAS DES state was allocated. In that case no RAS DES
mutex was initialized, so there is nothing to destroy.

| In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: Fix potential NULL pointer dereference
dasd_release_space() checks the implementation of the is_ese()
discipline function before calling it to determine if a given device is
an ESE DASD.
The current usage of the logical AND operator will lead to a NULL
pointer dereference as the function is called even if the function
pointer is NULL.
Fix this by using the logical OR operator. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: conntrack: revert ct extension genid infrastructure
This infrastructure is not used anymore after moving ct timeout and
helper to use datapath refcount to track object use.
Revert commit c56716c69ce1 ("netfilter: extensions: introduce extension
genid count") this patch disables all ct extensions (leading to NULL)
for unconfirmed conntracks, when this is only targeted at ct helper and
ct timeout. There is also codebase that dereferences the ct extension
without checking for NULL which could lead to crash. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/rockchip: dw_dp: Fix null-ptr-deref in dw_dp_remove()
Attempting to access driver data in the platform driver ->remove()
callback may lead to a null pointer dereference since there is no
guaranty that the component ->bind() callback invoking
platform_set_drvdata() was executed.
A common scenario is when Rockchip DRM driver didn't manage to run
component_bind_all() because of an (unrelated) error causing early
return from rockchip_drm_bind().
Drop the unnecessary call to platform_get_drvdata() and, instead,
reference the target device structure via platform_device. |
| In the Linux kernel, the following vulnerability has been resolved:
erofs: ensure valid f_path for page cache sharing
Previously, backing files for page cache sharing were set up with
f_path left as NULL (only f_inode was valid). It worked, but a recent
mincore fix relies on f_path.mnt and crashes (found by "erofs/028" on
7.2-rc4):
BUG: kernel NULL pointer dereference, address: 0000000000000018
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page
PGD 0 P4D 0
Oops: Oops: 0000 [#1] SMP PTI
CPU: 3 UID: 0 PID: 675528 Comm: fincore Not tainted 7.2.0-rc4-00002-g[]-dirty #1 PREEMPT(lazy)
Hardware name: Red Hat KVM, BIOS 1.16.0-4.al8 04/01/2014
RIP: 0010:__do_sys_mincore+0xc0/0x2c0
...
Specify valid paths using valid disconnected dentries together with
erofs_ishare_mnt instead of leaving f_path empty, so they are more
like real backing files in a pseudo filesystem and standard
backing_file_open() can be used directly. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: cs40l50-vibra - validate custom data from user space
cs40l50_add() copies the custom data of an FF_PERIODIC/FF_CUSTOM effect
straight from the ff_effect the user passed to EVIOCSFF, without
requiring it to hold anything:
work_data.custom_data = memdup_array_user(periodic->custom_data,
periodic->custom_len,
sizeof(s16));
work_data.custom_len = periodic->custom_len;
The driver then reads two words out of that buffer: custom_data[0] as the
waveform bank in cs40l50_effect_bank_set(), and custom_data[1] as the
index within the bank in cs40l50_effect_index_set(). Neither read is
covered by a length check, and custom_len is fully user controlled:
- custom_len == 0 makes memdup_array_user() call memdup_user() with a
length of zero, which returns ZERO_SIZE_PTR rather than an error, so
custom_data[0] dereferences it.
- custom_len == 1 allocates two bytes. A bank of ROM or RAM keeps
effect->type out of the OWT case, and custom_data[1] is then read one
word past the allocation.
The bank value itself is also mishandled. It is masked with
CS40L50_CUSTOM_DATA_MASK (0xffff) but stored in an s16, so a
custom_data[0] of 0x8000 or above wraps to a negative value that passes
the "bank_type >= CS40L50_WVFRM_BANK_NUM" test.
cs40l50_effect_index_set() indexes vib->dsp.banks[] with it before the
switch statement's default case gets a chance to reject it:
base_index = vib->dsp.banks[effect->type].base_index;
max_index = vib->dsp.banks[effect->type].max_index;
Require the two words the driver reads to be present, and hold the masked
bank in a u32 so the existing upper-bound test covers the whole range.
The da7280 haptic driver already range checks custom_len this way. |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: spacemit: fix NULL check in spacemit_pin_set_config
spacemit_pin_set_config() looks up the per-pin descriptor with
spacemit_get_pin() then checks the wrong variable for failure:
const struct spacemit_pin *spin = spacemit_get_pin(pctrl, pin);
...
if (!pin)
return -EINVAL;
reg = spacemit_pin_to_reg(pctrl, spin->pin);
pin is an unsigned int pin id, where 0 (GPIO_0 / gmac0_rxdv on K3) is a
valid pin, so rejecting it here drops the PAD config write for the first
pin of every group. On K3 Pico-ITX the GMAC RGMII group lists pin 0 as
its first entry, so its drive-strength / bias configuration was silently
ignored.
The intended guard is against spacemit_get_pin() returning NULL when the
pin id isn't in the SoC's pin table. Check spin instead, which both
restores PAD setup for pin 0 and prevents a NULL deref on spin->pin. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: Fix NULL pointer dereference in mt7996_init_tx_queues()
When MT76_NPU and CONFIG_NET_MEDIATEK_SOC_WED are enabled and
mt76 detects properly the Airoha NPU SoC, mt7996_init_tx_queues() will
dereference a NULL WED pointer.
Fix the issue by always passing the WED pointer from mt7996_dma_init(). |
