GHSA-557G-5W49-23J4

Vulnerability from github – Published: 2025-07-10 09:32 – Updated: 2025-11-19 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

nvmem: zynqmp_nvmem: unbreak driver after cleanup

Commit 29be47fcd6a0 ("nvmem: zynqmp_nvmem: zynqmp_nvmem_probe cleanup") changed the driver to expect the device pointer to be passed as the "context", but in nvmem the context parameter comes from nvmem_config.priv which is never set - Leading to null pointer exceptions when the device is accessed.

Severity

5.5 (Medium)

GHSA-558H-5PV9-XXG9

Vulnerability from github – Published: 2022-06-29 00:00 – Updated: 2025-11-03 21:30

Details

DCMTK through 3.6.6 does not handle string copy properly. Sending specific requests to the dcmqrdb program, it would query its database and copy the result even if the result is null, which can incur a head-based overflow. An attacker can use it to launch a DoS attack.

Severity

7.5 (High)

GHSA-558H-MQ8X-7Q9G

Vulnerability from github – Published: 2023-03-24 21:57 – Updated: 2023-03-27 22:00

Summary

TensorFlow has Null Pointer Error in SparseSparseMaximum

Details

Impact

When SparseSparseMaximum is given invalid sparse tensors as inputs, it can give an NPE.

import tensorflow as tf
tf.raw_ops.SparseSparseMaximum(
 a_indices=[[1]],
 a_values =[ 0.1 ],
 a_shape = [2],
 b_indices=[[]],
 b_values =[2 ],
 b_shape = [2],
)

Patches

We have patched the issue in GitHub commit 5e0ecfb42f5f65629fd7a4edd6c4afe7ff0feb04.

The fix will be included in TensorFlow 2.12. We will also cherrypick this commit on TensorFlow 2.11.1.

GHSA-559C-J26R-95QC

Vulnerability from github – Published: 2024-04-28 15:30 – Updated: 2025-01-14 15:30

Details

In the Linux kernel, the following vulnerability has been resolved:

sfc: fix null pointer dereference in efx_hard_start_xmit

Trying to get the channel from the tx_queue variable here is wrong because we can only be here if tx_queue is NULL, so we shouldn't dereference it. As the above comment in the code says, this is very unlikely to happen, but it's wrong anyway so let's fix it.

I hit this issue because of a different bug that caused tx_queue to be NULL. If that happens, this is the error message that we get here: BUG: unable to handle kernel NULL pointer dereference at 0000000000000020 [...] RIP: 0010:efx_hard_start_xmit+0x153/0x170 [sfc]

GHSA-55J6-RJHX-HWFH

Vulnerability from github – Published: 2026-07-01 17:41 – Updated: 2026-07-01 17:41

Summary

Open Babel has NULL pointer dereference in CACAO CacaoFormat::SetHilderbrandt

Details

Summary

A memory-safety vulnerability in Open Babel's CACAO parser caused a NULL pointer dereference when reading a crafted input file.

Details

The flaw was in CacaoFormat::SetHilderbrandt. A malformed input caused the parser to dereference a NULL pointer while applying the Hilderbrandt transformation.

Impact

Open Babel is a C++ library and CLI used to read and write chemistry file formats; it is shipped by Linux distributions and embedded in services that may parse untrusted input. Triggering this vulnerability requires the victim to open a malicious CACAO file with the obabel tool, the OBConversion API, or any of the language bindings (Python, Ruby, Java, R, Perl, C#, PHP).

Affected versions

All releases up to and including 3.1.1.

Patched version

3.2.0 (released 2026-05-26).

Patch

Fix commit: https://github.com/openbabel/openbabel/commit/ecaed96f Originally reported as #2827; fixes consolidated in #2913.

A minimized reproducer for this CVE is checked in under test/files/fuzz_regress/ and is exercised on every CI build under ASAN+UBSAN by the fuzzregresstest harness.

Credit

Reported via OSS-Fuzz.

Severity

5.5 (Medium)

GHSA-55JJ-QFP9-6XV9

Vulnerability from github – Published: 2026-01-23 06:31 – Updated: 2026-01-23 06:31

Details

A flaw was found in SIPp. A remote attacker could exploit this by sending specially crafted Session Initiation Protocol (SIP) messages during an active call. This vulnerability, a NULL pointer dereference, can cause the application to crash, leading to a denial of service. Under specific conditions, it may also allow an attacker to execute unauthorized code, compromising the system's integrity and availability.

Severity

8.4 (High)

Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-12-04 15:30

Details

In the Linux kernel, the following vulnerability has been resolved:

drm/bridge: megachips: Fix a null pointer dereference bug

When removing the module we will get the following warning:

[ 31.911505] i2c-core: driver [stdp2690-ge-b850v3-fw] unregistered [ 31.912484] general protection fault, probably for non-canonical address 0xdffffc0000000001: 0000 [#1] PREEMPT SMP KASAN PTI [ 31.913338] KASAN: null-ptr-deref in range [0x0000000000000008-0x000000000000000f] [ 31.915280] RIP: 0010:drm_bridge_remove+0x97/0x130 [ 31.921825] Call Trace: [ 31.922533] stdp4028_ge_b850v3_fw_remove+0x34/0x60 [megachips_stdpxxxx_ge_b850v3_fw] [ 31.923139] i2c_device_remove+0x181/0x1f0

The two bridges (stdp2690, stdp4028) do not probe at the same time, so the driver does not call ge_b850v3_resgiter() when probing, causing the driver to try to remove the object that has not been initialized.

Fix this by checking whether both the bridges are probed.

Severity

5.5 (Medium)
