It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-38222 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-38222/ (Markdown: https://insights.sbomify.com/CVE-2025-38222/index.md)","id":"CVE-2025-38222","markdown":"https://insights.sbomify.com/CVE-2025-38222/index.md","name":"CVE-2025-38222","record":{"aliases":["AZL-64746","BELL-CVE-2025-38222","DEBIAN-CVE-2025-38222","GHSA-4x5c-w433-979g","ROOT-OS-DEBIAN-11-CVE-2025-38222","ROOT-OS-DEBIAN-12-CVE-2025-38222","ROOT-OS-UBUNTU-2204-CVE-2025-38222","ROOT-OS-UBUNTU-2404-CVE-2025-38222","UBUNTU-CVE-2025-38222"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel ext4","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel crash in the ext4 filesystem by exploiting an integer overflow in inline data handling when the inline_data feature is enabled.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\next4: inline: fix len overflow in ext4_prepare_inline_data\n\nWhen running the following code on an ext4 filesystem with inline_data\nfeature enabled, it will lead to the bug below.\n\n        fd = open(\"file1\", O_RDWR | O_CREAT | O_TRUNC, 0666);\n        ftruncate(fd, 30);\n        pwrite(fd, \"a\", 1, (1UL \u003c\u003c 40) + 5UL);\n\nThat happens because write_begin will succeed as when\next4_generic_write_inline_data calls ext4_prepare_inline_data, pos + len\nwill be truncated, leading to ext4_prepare_inline_data parameter to be 6\ninstead of 0x10000000006.\n\nThen, later when write_end is called, we hit:\n\n        BUG_ON(pos + len \u003e EXT4_I(inode)-\u003ei_inline_size);\n\nat ext4_write_inline_data.\n\nFix it by using a loff_t type for the len parameter in\next4_prepare_inline_data instead of an unsigned int.\n\n[   44.545164] ------------[ cut here ]------------\n[   44.545530] kernel BUG at fs/ext4/inline.c:240!\n[   44.545834] Oops: invalid opcode: 0000 [#1] SMP NOPTI\n[   44.546172] CPU: 3 UID: 0 PID: 343 Comm: test Not tainted 6.15.0-rc2-00003-g9080916f4863 #45 PREEMPT(full)  112853fcebfdb93254270a7959841d2c6aa2c8bb\n[   44.546523] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014\n[   44.546523] RIP: 0010:ext4_write_inline_data+0xfe/0x100\n[   44.546523] Code: 3c 0e 48 83 c7 48 48 89 de 5b 41 5c 41 5d 41 5e 41 5f 5d e9 e4 fa 43 01 5b 41 5c 41 5d 41 5e 41 5f 5d c3 cc cc cc cc cc 0f 0b \u003c0f\u003e 0b 0f 1f 44 00 00 55 41 57 41 56 41 55 41 54 53 48 83 ec 20 49\n[   44.546523] RSP: 0018:ffffb342008b79a8 EFLAGS: 00010216\n[   44.546523] RAX: 0000000000000001 RBX: ffff9329c579c000 RCX: 0000010000000006\n[   44.546523] RDX: 000000000000003c RSI: ffffb342008b79f0 RDI: ffff9329c158e738\n[   44.546523] RBP: 0000000000000001 R08: 0000000000000001 R09: 0000000000000000\n[   44.546523] R10: 00007ffffffff000 R11: ffffffff9bd0d910 R12: 0000006210000000\n[   44.546523] R13: fffffc7e4015e700 R14: 0000010000000005 R15: ffff9329c158e738\n[   44.546523] FS:  00007f4299934740(0000) GS:ffff932a60179000(0000) knlGS:0000000000000000\n[   44.546523] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[   44.546523] CR2: 00007f4299a1ec90 CR3: 0000000002886002 CR4: 0000000000770eb0\n[   44.546523] PKRU: 55555554\n[   44.546523] Call Trace:\n[   44.546523]  \u003cTASK\u003e\n[   44.546523]  ext4_write_inline_data_end+0x126/0x2d0\n[   44.546523]  generic_perform_write+0x17e/0x270\n[   44.546523]  ext4_buffered_write_iter+0xc8/0x170\n[   44.546523]  vfs_write+0x2be/0x3e0\n[   44.546523]  __x64_sys_pwrite64+0x6d/0xc0\n[   44.546523]  do_syscall_64+0x6a/0xf0\n[   44.546523]  ?
