CVSS v3.1 |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Versions 14.10.1 and below have a NULL pointer dereference vulnerability in the MSL (Magick Scripting Language) parser when processing <comment> tags before images are loaded. This can lead to DoS attack due to assertion failure (debug builds) or NULL pointer dereference (release builds). This issue is fixed in version 14.10.2. |
| A flaw was found in libssh, a library that implements the SSH protocol. When calculating the session ID during the key exchange (KEX) process, an allocation failure in cryptographic functions may lead to a NULL pointer dereference. This issue can cause the client or server to crash. |
| A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Validate the box size for the snooped cursor
Invalid userspace dma surface copies could potentially overflow
the memcpy from the surface to the snooped image leading to crashes.
To fix it the dimensions of the copybox have to be validated
against the expected size of the snooped cursor. |
| EVerest is an EV charging software stack. Prior to version 2025.10.0, during the deserialization of a `DC_ChargeLoopRes` message that includes Receipt as well as TaxCosts, the vector `<DetailedTax>tax_costs` in the target `Receipt` structure is accessed out of bounds. This occurs in the method `template <> void convert(const struct iso20_dc_DetailedTaxType& in, datatypes::DetailedTax& out)` which leads to a null pointer dereference and causes the module to terminate. The EVerest processes and all its modules shut down, affecting all EVSE. Version 2025.10.0 fixes the issue. |
| A security flaw has been discovered in nicbarker clay up to 0.14. This affects the function Clay__MeasureTextCached in the library clay.h. The manipulation results in null pointer dereference. The attack is only possible with local access. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet. |
| A NULL pointer dereference in the dacp_reply_playqueueedit_move function (src/httpd_dacp.c) of owntone-server commit b7e385f allows attackers to cause a Denial of Service (DoS) via sending a crafted DACP request to the server. |
| A NULL pointer dereference in the parse_meta function (src/httpd_daap.c) of owntone-server commit 334beb allows attackers to cause a Denial of Service (DoS) via sending a crafted DAAP request to the server. |
| NULL pointer dereference in the dacp_reply_playqueueedit_clear function in src/httpd_dacp.c in owntone-server through commit 6d604a1 (newer commit after version 28.12) allows remote attackers to cause a Denial of Service (crash). |
| NULL pointer dereference in the daap_reply_groups function in src/httpd_daap.c in owntone-server through commit 5e6f19a (newer commit after version 28.2) allows remote attackers to cause a Denial of Service. |
| A flaw was found in the FreeRDP used by Anaconda's remote install feature, where a crafted RDP packet could trigger a segmentation fault. This issue causes the service to crash and remain defunct, resulting in a denial of service. It occurs pre-boot and is likely due to a NULL pointer dereference. Rebooting is required to recover the system. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_qfq: Fix NULL deref when deactivating inactive aggregate in qfq_reset
`qfq_class->leaf_qdisc->q.qlen > 0` does not imply that the class
itself is active.
Two qfq_class objects may point to the same leaf_qdisc. This happens
when:
1. one QFQ qdisc is attached to the dev as the root qdisc, and
2. another QFQ qdisc is temporarily referenced (e.g., via qdisc_get()
/ qdisc_put()) and is pending to be destroyed, as in function
tc_new_tfilter.
When packets are enqueued through the root QFQ qdisc, the shared
leaf_qdisc->q.qlen increases. At the same time, the second QFQ
qdisc triggers qdisc_put and qdisc_destroy: the qdisc enters
qfq_reset() with its own q->q.qlen == 0, but its class's leaf
qdisc->q.qlen > 0. Therefore, the qfq_reset would wrongly deactivate
an inactive aggregate and trigger a null-deref in qfq_deactivate_agg:

As a result, the problem occurs. Null pointer detection is added to
prevent problems. |

x86/fpu: Fix copy_xstate_to_uabi() to copy init states correctly
When an extended state component is not present in fpstate, but in init
state, the function copies from init_fpstate via copy_feature().
But, dynamic states are not present in init_fpstate because of all-zeros
init states. Then retrieving them from init_fpstate will explode like this:

Adjust the 'mask' to zero out the userspace buffer for the features that
are not available both from fpstate and from init_fpstate.
The dynamic features depend on the compacted XSAVE format. Ensure it is
enabled before reading XCOMP_BV in init_fpstate. |
| In the Linux kernel, the following vulnerability has been resolved:
pwm: lpc32xx: Remove handling of PWM channels
Because LPC32xx PWM controllers have only a single output which is
registered as the only PWM device/channel per controller, it is known in
advance that pwm->hwpwm value is always 0. On basis of this fact
simplify the code by removing operations with pwm->hwpwm, there is no
controls which require channel number as input.
Even though I wasn't aware at the time when I forward ported that patch,
this fixes a null pointer dereference as lpc32xx->chip.pwms is NULL
before devm_pwmchip_add() is called. |
| In the Linux kernel, the following vulnerability has been resolved:
iw_cxgb4: Fix potential NULL dereference in c4iw_fill_res_cm_id_entry()
This condition needs to match the previous "if (epcp->state == LISTEN) {"
exactly to avoid a NULL dereference of either "listen_ep" or "ep". The
problem is that "epcp" has been re-assigned so just testing
"if (epcp->state == LISTEN) {" a second time is not sufficient. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Lag, fix failure to cancel delayed bond work
Commit 0d4e8ed139d8 ("net/mlx5: Lag, avoid lockdep warnings")
accidentally removed a call to cancel delayed bond work thus it may
cause queued delay to expire and fall on an already destroyed work
queue.
Fix by restoring the call cancel_delayed_work_sync() before
destroying the workqueue.
This prevents call trace such as this:
