| CVE-2024-23078 | Cri | 0.59 | 9.1 | 0.00 | Apr 8, 2024 | JGraphT Core v1.5.2 was discovered to contain a NullPointerException via the component org.jgrapht.alg.util.ToleranceDoubleComparator::compare(Double, Double). NOTE: this is disputed by multiple third parties who believe there was not reasonable evidence to determine the existence of a vulnerability. The submission may have been based on a tool that is not sufficiently robust for vulnerability identification. | |
| CVE-2017-10917 | Cri | 0.59 | 9.1 | 0.01 | Jul 5, 2017 | Xen through 4.8.x does not validate the port numbers of polled event channel ports, which allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) or possibly obtain sensitive information, aka XSA-221. | |
| CVE-2017-5149 | Hig | 0.58 | 8.9 | 0.00 | Feb 13, 2017 | An issue was discovered in St. Jude Medical Merlin@home, versions prior to Version 8.2.2 (RF models: EX1150; Inductive models: EX1100; and Inductive models: EX1100 with MerlinOnDemand capability). The identities of the endpoints for the communication channel between the transmitter and St. Jude Medical's web site, Merlin.net, are not verified. This may allow a man-in-the-middle attacker to access or influence communications between the identified endpoints. | |
| CVE-2026-43113 | Hig | 0.57 | 8.8 | 0.00 | May 6, 2026 | In the Linux kernel, the following vulnerability has been resolved: wifi: wl1251: validate packet IDs before indexing tx_frames wl1251_tx_packet_cb() uses the firmware completion ID directly to index the fixed 16-entry wl->tx_frames[] array. The ID is a raw u8 from the completion block, and the callback does not currently verify that it fits the array before dereferencing it. Reject completion IDs that fall outside wl->tx_frames[] and keep the existing NULL check in the same guard. This keeps the fix local to the trust boundary and avoids touching the rest of the completion flow. | |
| CVE-2026-31450 | Hig | 0.57 | 8.8 | 0.00 | Apr 22, 2026 | In the Linux kernel, the following vulnerability has been resolved: ext4: publish jinode after initialization ext4_inode_attach_jinode() publishes ei->jinode to concurrent users. It used to set ei->jinode before jbd2_journal_init_jbd_inode(), allowing a reader to observe a non-NULL jinode with i_vfs_inode still unset. The fast commit flush path can then pass this jinode to jbd2_wait_inode_data(), which dereferences i_vfs_inode->i_mapping and may crash. Below is the crash I observe: ``` BUG: unable to handle page fault for address: 000000010beb47f4 PGD 110e51067 P4D 110e51067 PUD 0 Oops: Oops: 0000 [#1] SMP NOPTI CPU: 1 UID: 0 PID: 4850 Comm: fc_fsync_bench_ Not tainted 6.18.0-00764-g795a690c06a5 #1 PREEMPT(voluntary) Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.17.0-2-2 04/01/2014 RIP: 0010:xas_find_marked+0x3d/0x2e0 Code: e0 03 48 83 f8 02 0f 84 f0 01 00 00 48 8b 47 08 48 89 c3 48 39 c6 0f 82 fd 01 00 00 48 85 c9 74 3d 48 83 f9 03 77 63 4c 8b 0f <49> 8b 71 08 48 c7 47 18 00 00 00 00 48 89 f1 83 e1 03 48 83 f9 02 RSP: 0018:ffffbbee806e7bf0 EFLAGS: 00010246 RAX: 000000000010beb4 RBX: 000000000010beb4 RCX: 0000000000000003 RDX: 0000000000000001 RSI: 0000002000300000 RDI: ffffbbee806e7c10 RBP: 0000000000000001 R08: 0000002000300000 R09: 000000010beb47ec R10: ffff9ea494590090 R11: 0000000000000000 R12: 0000002000300000 R13: ffffbbee806e7c90 R14: ffff9ea494513788 R15: ffffbbee806e7c88 FS: 00007fc2f9e3e6c0(0000) GS:ffff9ea6b1444000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000010beb47f4 CR3: 0000000119ac5000 CR4: 0000000000750ef0 PKRU: 55555554 Call Trace: <TASK> filemap_get_folios_tag+0x87/0x2a0 __filemap_fdatawait_range+0x5f/0xd0 ? srso_alias_return_thunk+0x5/0xfbef5 ? __schedule+0x3e7/0x10c0 ? srso_alias_return_thunk+0x5/0xfbef5 ? srso_alias_return_thunk+0x5/0xfbef5 ? srso_alias_return_thunk+0x5/0xfbef5 ? preempt_count_sub+0x5f/0x80 ? srso_alias_return_thunk+0x5/0xfbef5 ? cap_safe_nice+0x37/0x70 ? srso_alias_return_thunk+0x5/0xfbef5 ? preempt_count_sub+0x5f/0x80 ? srso_alias_return_thunk+0x5/0xfbef5 filemap_fdatawait_range_keep_errors+0x12/0x40 ext4_fc_commit+0x697/0x8b0 ? ext4_file_write_iter+0x64b/0x950 ? srso_alias_return_thunk+0x5/0xfbef5 ? preempt_count_sub+0x5f/0x80 ? srso_alias_return_thunk+0x5/0xfbef5 ? vfs_write+0x356/0x480 ? srso_alias_return_thunk+0x5/0xfbef5 ? preempt_count_sub+0x5f/0x80 ext4_sync_file+0xf7/0x370 do_fsync+0x3b/0x80 ? syscall_trace_enter+0x108/0x1d0 __x64_sys_fdatasync+0x16/0x20 do_syscall_64+0x62/0x2c0 entry_SYSCALL_64_after_hwframe+0x76/0x7e ... ``` Fix this by initializing the jbd2_inode first.

| CVE-2024-9472 | Hig | 0.57 | — | 0.00 | Nov 14, 2024 | A null pointer dereference in Palo Alto Networks PAN-OS software on PA-800 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series hardware platforms when Decryption policy is enabled allows an unauthenticated attacker to crash PAN-OS by sending specific traffic through the data plane, resulting in a denial of service (DoS) condition. Repeated attempts to trigger this condition will result in PAN-OS entering maintenance mode. Palo Alto Networks VM-Series, Cloud NGFW, and Prisma Access are not affected. This issue only affects PA-800 Series, PA-3200 Series, PA-5200 Series, and PA-7000 Series running these specific versions of PAN-OS: * 10.2.7-h12 * 10.2.8-h10 * 10.2.9-h9 * 10.2.9-h11 * 10.2.10-h2 * 10.2.10-h3 * 10.2.11 * 10.2.11-h1 * 10.2.11-h2 * 10.2.11-h3 * 11.1.2-h9 * 11.1.2-h12 * 11.1.3-h2 * 11.1.3-h4 * 11.1.3-h6 * 11.2.2 * 11.2.2-h1 | |
