| CVE-2026-23952 | 1 Imagemagick | 1 Imagemagick | 2026-01-22 | 6.5 Medium |
| 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. | ||||
| CVE-2025-15504 | 1 Lief-project | 1 Lief | 2026-01-22 | 3.3 Low |
| A security flaw has been discovered in lief-project LIEF up to 0.17.1. Affected by this issue is the function Parser::parse_binary of the file src/ELF/Parser.tcc of the component ELF Binary Parser. The manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.17.2 can resolve this issue. The patch is identified as 81bd5d7ea0c390563f1c4c017c9019d154802978. It is recommended to upgrade the affected component. | ||||
| CVE-2025-21973 | 1 Linux | 1 Linux Kernel | 2026-01-22 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: eth: bnxt: fix kernel panic in the bnxt_get_queue_stats{rx | tx} When qstats-get operation is executed, callbacks of netdev_stats_ops are called. The bnxt_get_queue_stats{rx | tx} collect per-queue stats from sw_stats in the rings. But {rx | tx | cp}_ring are allocated when the interface is up. So, these rings are not allocated when the interface is down. The qstats-get is allowed even if the interface is down. However, the bnxt_get_queue_stats{rx | tx}() accesses cp_ring and tx_ring without null check. So, it needs to avoid accessing rings if the interface is down. Reproducer: ip link set $interface down ./cli.py --spec netdev.yaml --dump qstats-get OR ip link set $interface down python ./stats.py Splat looks like: BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 1680fa067 P4D 1680fa067 PUD 16be3b067 PMD 0 Oops: Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 0 UID: 0 PID: 1495 Comm: python3 Not tainted 6.14.0-rc4+ #32 5cd0f999d5a15c574ac72b3e4b907341 Hardware name: ASUS System Product Name/PRIME Z690-P D4, BIOS 0603 11/01/2021 RIP: 0010:bnxt_get_queue_stats_rx+0xf/0x70 [bnxt_en] Code: c6 87 b5 18 00 00 02 eb a2 66 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 0f 1f 44 01 RSP: 0018:ffffabef43cdb7e0 EFLAGS: 00010282 RAX: 0000000000000000 RBX: ffffffffc04c8710 RCX: 0000000000000000 RDX: ffffabef43cdb858 RSI: 0000000000000000 RDI: ffff8d504e850000 RBP: ffff8d506c9f9c00 R08: 0000000000000004 R09: ffff8d506bcd901c R10: 0000000000000015 R11: ffff8d506bcd9000 R12: 0000000000000000 R13: ffffabef43cdb8c0 R14: ffff8d504e850000 R15: 0000000000000000 FS: 00007f2c5462b080(0000) GS:ffff8d575f600000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 0000000167fd0000 CR4: 00000000007506f0 PKRU: 55555554 Call Trace: <TASK> ? __die+0x20/0x70 ? page_fault_oops+0x15a/0x460 ? sched_balance_find_src_group+0x58d/0xd10 ? exc_page_fault+0x6e/0x180 ? asm_exc_page_fault+0x22/0x30 ? bnxt_get_queue_stats_rx+0xf/0x70 [bnxt_en cdd546fd48563c280cfd30e9647efa420db07bf1] netdev_nl_stats_by_netdev+0x2b1/0x4e0 ? xas_load+0x9/0xb0 ? xas_find+0x183/0x1d0 ? xa_find+0x8b/0xe0 netdev_nl_qstats_get_dumpit+0xbf/0x1e0 genl_dumpit+0x31/0x90 netlink_dump+0x1a8/0x360 | ||||

| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: l2cap: fix null-ptr-deref in l2cap_chan_timeout There is a race condition between l2cap_chan_timeout() and l2cap_chan_del(). When we use l2cap_chan_del() to delete the channel, the chan->conn will be set to null. But the conn could be dereferenced again in the mutex_lock() of l2cap_chan_timeout(). As a result the null pointer dereference bug will happen.

| CVE-2025-68141 | 1 Everest | 1 Everest-core | 2026-01-22 | 7.4 High |
| 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. | ||||
| CVE-2025-66646 | 1 Riot-os | 1 Riot | 2026-01-22 | 7.5 High |
| RIOT is an open-source microcontroller operating system, designed to match the requirements of Internet of Things (IoT) devices and other embedded devices. A vulnerability was discovered in the IPv6 fragmentation reassembly implementation of RIOT OS v2025.07. When receiving an fragmented IPv6 packet with fragment offset 0 and an empty payload, the payload pointer is set to NULL. However, the implementation still tries to copy the payload into the reassembly buffer, resulting in a NULL pointer dereference which crashes the OS (DoS). To trigger the vulnerability, the `gnrc_ipv6_ext_frag` module must be enabled and the attacker must be able to send arbitrary IPv6 packets to the victim. RIOT OS v2025.10 fixes the issue. | ||||
| CVE-2025-8114 | 2 Libssh, Redhat | 3 Libssh, Enterprise Linux, Openshift | 2026-01-22 | 4.7 Medium |
| 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. | ||||
| CVE-2025-6395 | 1 Redhat | 7 Ceph Storage, Discovery, Enterprise Linux and 4 more | 2026-01-22 | 6.5 Medium |

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. | ||||
| CVE-2026-22976 | 1 Linux | 1 Linux Kernel | 2026-01-21 | 5.5 Medium |
| 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: [ 0.903172] BUG: kernel NULL pointer dereference, address: 0000000000000000 [ 0.903571] #PF: supervisor write access in kernel mode [ 0.903860] #PF: error_code(0x0002) - not-present page [ 0.904177] PGD 10299b067 P4D 10299b067 PUD 10299c067 PMD 0 [ 0.904502] Oops: Oops: 0002 [#1] SMP NOPTI [ 0.904737] CPU: 0 UID: 0 PID: 135 Comm: exploit Not tainted 6.19.0-rc3+ #2 NONE [ 0.905157] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.17.0-0-gb52ca86e094d-prebuilt.qemu.org 04/01/2014 [ 0.905754] RIP: 0010:qfq_deactivate_agg (include/linux/list.h:992 (discriminator 2) include/linux/list.h:1006 (discriminator 2) net/sched/sch_qfq.c:1367 (discriminator 2) net/sched/sch_qfq.c:1393 (discriminator 2)) [ 0.906046] Code: 0f 84 4d 01 00 00 48 89 70 18 8b 4b 10 48 c7 c2 ff ff ff ff 48 8b 78 08 48 d3 e2 48 21 f2 48 2b 13 48 8b 30 48 d3 ea 8b 4b 18 0 Code starting with the faulting instruction =========================================== 0: 0f 84 4d 01 00 00 je 0x153 6: 48 89 70 18 mov %rsi,0x18(%rax) a: 8b 4b 10 mov 0x10(%rbx),%ecx d: 48 c7 c2 ff ff ff ff mov $0xffffffffffffffff,%rdx 14: 48 8b 78 08 mov 0x8(%rax),%rdi 18: 48 d3 e2 shl %cl,%rdx 1b: 48 21 f2 and %rsi,%rdx 1e: 48 2b 13 sub (%rbx),%rdx 21: 48 8b 30 mov (%rax),%rsi 24: 48 d3 ea shr %cl,%rdx 27: 8b 4b 18 mov 0x18(%rbx),%ecx ...
