| CVE-2026-52941 | 1 Linux | 1 Linux Kernel | 2026-06-24 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net/smc: avoid NULL deref of conn->lnk in smc_msg_event tracepoint The smc_msg_event tracepoint class, shared by smc_tx_sendmsg and smc_rx_recvmsg, unconditionally dereferences smc->conn.lnk: __string(name, smc->conn.lnk->ibname) conn->lnk is only set for SMC-R; for SMC-D it is NULL. Other code on these paths already handles this (e.g. !conn->lnk in SMC_STAT_RMB_TX_SIZE_SMALL()). With the tracepoint enabled, the first sendmsg()/recvmsg() on an SMC-D socket crashes: Oops: general protection fault, probably for non-canonical address KASAN: null-ptr-deref in range [...] RIP: 0010:strlen+0x1e/0xa0 Call Trace: trace_event_raw_event_smc_msg_event (net/smc/smc_tracepoint.h:44) smc_rx_recvmsg (net/smc/smc_rx.c:515) smc_recvmsg (net/smc/af_smc.c:2859) __sys_recvfrom (net/socket.c:2315) __x64_sys_recvfrom (net/socket.c:2326) do_syscall_64 The faulting address 0x3e0 is offsetof(struct smc_link, ibname), confirming the NULL ->lnk deref. Enabling the tracepoint requires root, but the trigger itself is unprivileged: socket(AF_SMC, ...) has no capability check, and SMC-D negotiation needs no admin step on s390 or on x86 with the loopback ISM device loaded. Log an empty device name for SMC-D instead of dereferencing NULL. | ||||
| CVE-2025-55639 | 1 Gpac | 2 Gpac, Mp4box | 2026-06-24 | 6.5 Medium |
| 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. | ||||
| CVE-2026-34662 | 3 Adobe, Apple, Microsoft | 3 Illustrator, Macos, Windows | 2026-06-23 | 5.5 Medium |
| 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. | ||||
| CVE-2023-2609 | 2 Fedoraproject, Vim | 2 Fedora, Vim | 2026-06-23 | 5.5 Medium |
| NULL Pointer Dereference in GitHub repository vim/vim prior to 9.0.1531. | ||||
| CVE-2026-2903 | 2 Re2c, Skvadrik | 2 Re2c, Re2c | 2026-06-23 | 3.3 Low |
| 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. | ||||
| CVE-2026-48139 | 1 Ni | 3 Grpc-device, Instrumentstudio, Ni Grpc Device Server | 2026-06-22 | 7.5 High |
| 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. | ||||
| CVE-2026-8050 | 1 Signalrgb | 1 Signalrgb Kernel Driver | 2026-06-20 | 7.5 High |
| 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. | ||||
| CVE-2026-46296 | 1 Linux | 1 Linux Kernel | 2026-06-19 | 5.5 Medium |
| 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. | ||||
| CVE-2026-31727 | 1 Linux | 1 Linux Kernel | 2026-06-19 | 5.5 Medium |
| 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. | ||||
| CVE-2021-47211 | 1 Linux | 1 Linux Kernel | 2026-06-19 | 5.5 Medium |
| 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. | ||||
| CVE-2025-55663 | 1 Gpac | 2 Gpac, Mp4box | 2026-06-19 | 5.5 Medium |
| 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. | ||||
| CVE-2026-55204 | 1 Haproxy | 2 Aloha, Haproxy | 2026-06-19 | 7.5 High |
| 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. | ||||
| CVE-2026-48985 | 1 Mcdope | 1 Pam Usb | 2026-06-18 | 5.5 Medium |
| 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. | ||||
| CVE-2025-55643 | 1 Gpac | 2 Gpac, Mp4box | 2026-06-18 | 5.5 Medium |
| 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. | ||||
| CVE-2025-55641 | 1 Gpac | 2 Gpac, Mp4box | 2026-06-18 | 5.5 Medium |
| 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. | ||||
| CVE-2025-55649 | 1 Gpac | 2 Gpac, Mp4box | 2026-06-18 | 5.5 Medium |
| 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. | ||||

| CVE-2026-1288 | 1 Autodesk | 1 Revit | 2026-06-17 | 5.5 Medium |
| 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. | ||||
| CVE-2026-22899 | 2 Qnap, Qnap Systems | 2 File Station, File Station 5 | 2026-06-17 | 6.5 Medium |
| A NULL pointer dereference vulnerability has been reported to affect File Station 6. If a remote attacker gains a user account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack. We have already fixed the vulnerability in the following version: File Station 5 5.5.6.5208 and later | ||||
