| In the Linux kernel, the following vulnerability has been resolved:
batman-adv: v: stop OGMv2 on disabled interface
When a batadv_hard_iface is disabled, its mesh_iface pointer is set to
NULL. However, batadv_v_ogm_send_meshif() may still dispatch OGMs via
batadv_v_ogm_queue_on_if() for interfaces that have since lost their
mesh_iface association. This results in a NULL pointer dereference when
batadv_v_ogm_queue_on_if() unconditionally calls netdev_priv() on the
now NULL hard_iface->mesh_iface to retrieve the batadv_priv.
It is necessary to ensure that the batadv_v_ogm_queue_on_if() checks that
it is using the same mesh_iface for which batadv_v_ogm_send_meshif() was
called. |
| In the Linux kernel, the following vulnerability has been resolved:
net/rds: fix NULL deref in rds_ib_send_cqe_handler() on masked atomic completion
rds_ib_xmit_atomic() always programs a masked atomic opcode
(IB_WR_MASKED_ATOMIC_CMP_AND_SWP or IB_WR_MASKED_ATOMIC_FETCH_AND_ADD)
for every RDS atomic cmsg. But the completion-side switch in
rds_ib_send_unmap_op() only handles the non-masked opcodes, so a masked
atomic completion falls through to default and returns rm == NULL while
send->s_op is left set. rds_ib_send_cqe_handler() then dereferences the
NULL rm via rm->m_final_op, oopsing in softirq context. An unprivileged
AF_RDS sendmsg() of an atomic cmsg over an active RDS/IB connection
triggers it; on hardware that natively accepts masked atomics (mlx4,
mlx5) no extra setup is needed.
RDS/IB: rds_ib_send_unmap_op: unexpected opcode 0xd in WR!
Oops: general protection fault [#1] SMP KASAN
KASAN: null-ptr-deref in range [0x0000000000000190-0x0000000000000197]

Handle the masked atomic opcodes in the same case as the non-masked
ones: they map to the same struct rds_message.atomic union member, so
the existing container_of()/rds_ib_send_unmap_atomic() body is correct
for them. |
| GPAC MP4Box v2.4 was discovered to contain a NULL pointer dereference in the gf_isom_add_track_kind() function at isomedia/isom_write.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted MP4 file. |
| Illustrator versions 29.8.6, 30.3 and earlier are affected by a NULL Pointer Dereference vulnerability that could result in an application denial-of-service. An attacker could exploit this vulnerability to crash the application, leading to a denial-of-service condition. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| NULL Pointer Dereference in GitHub repository vim/vim prior to 9.0.1531. |
| A flaw has been found in skvadrik re2c up to 4.4. Impacted is the function check_and_merge_special_rules of the file src/parse/ast.cc. This manipulation causes null pointer dereference. The attack can only be executed locally. The exploit has been published and may be used. Patch name: febeb977936f9519a25d9fbd10ff8256358cdb97. It is suggested to install a patch to address this issue. |
| There is a NULL pointer dereference vulnerability in NI grpc-device in the data moniker service that may allow an attacker to cause a denial of service by triggering a crash. Successful exploitation requires an attacker to provide an unknown value to the data moniker service. This affects NI grpc-device 2.17.0 and prior versions. |
| In SignalRGB versions prior to 1.3.7.0, seven of the thirteen IOCTL handlers dereference the SystemBuffer pointer without first verifying that it is non-NULL. Sending an IOCTL with an empty input buffer causes a NULL pointer dereference, resulting in a kernel crash. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: s3c64xx: fix NULL-deref on driver unbind
A change moving DMA channel allocation from probe() back to
s3c64xx_spi_prepare_transfer() failed to remove the corresponding
deallocation from remove().
Drop the bogus DMA channel release from remove() to avoid triggering a
NULL-pointer dereference on driver unbind.
This issue was flagged by Sashiko when reviewing a controller
deregistration fix. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: u_ether: Fix NULL pointer deref in eth_get_drvinfo
Commit ec35c1969650 ("usb: gadget: f_ncm: Fix net_device lifecycle with
device_move") reparents the gadget device to /sys/devices/virtual during
unbind, clearing the gadget pointer. If the userspace tool queries on
the surviving interface during this detached window, this leads to a
NULL pointer dereference.
Unable to handle kernel NULL pointer dereference
Call trace:
eth_get_drvinfo+0x50/0x90
ethtool_get_drvinfo+0x5c/0x1f0
__dev_ethtool+0xaec/0x1fe0
dev_ethtool+0x134/0x2e0
dev_ioctl+0x338/0x560
Add a NULL check for dev->gadget in eth_get_drvinfo(). When detached,
skip copying the fw_version and bus_info strings, which is natively
handled by ethtool_get_drvinfo for empty strings. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: fix null pointer dereference on pointer cs_desc
The pointer cs_desc return from snd_usb_find_clock_source could
be null, so there is a potential null pointer dereference issue.
Fix this by adding a null check before dereference. |
| A segmentation violation in the Track_SetStreamDescriptor function (isomedia/track.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file. |
| HAProxy through 3.4.0, fixed in commit 9a6d1fe, contains a null pointer dereference vulnerability in hpack_dht_insert() within src/hpack-tbl.c that fails to validate the return value of hpack_dht_defrag() when the memory pool is exhausted. An attacker can trigger HPACK dynamic table insertions under memory pressure to dereference a NULL pointer and crash HAProxy worker processes, causing denial of service. |
| pam_usb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, pusb_is_loginctl_local() can cause a NULL dereference crash when parsing loginctl output. The function calls popen() and reads the result; if the Remote field is only a newline, fgets() succeeds but strtok_r(buf, "\n", &saveptr) returns NULL. A subsequent strcmp(is_remote, "no") then dereferences NULL, causing undefined behavior (typically SIGSEGV) and crashing the PAM module. This can crash the authenticating process (e.g., sudo, login) and, depending on PAM stack configuration, deny access for all users of the affected service. This issue has been fixed in version 0.9.2. |
| A NULL pointer dereference in the TrackWriter handling component (filters/mux_isom.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file. |
| A NULL pointer dereference in the gf_isom_copy_sample_info function (isomedia/isom_write.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file. |
| A NULL pointer dereference in the gf_media_map_esd function (media_tools/isom_tools.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file. |
| Memory safety bug fixed in Thunderbird ESR 140.12. This vulnerability was fixed in Firefox ESR 140.12 and Thunderbird 140.12. |
| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. |
| A maliciously crafted RFA file, when converted to FormIt via “Convert RFA to FormIt” in Autodesk Revit, can force a NULL Pointer Dereference vulnerability. Successful exploitation may cause the application to crash, leading to a denial-of-service condition. |
