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-2024-50151 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-50151/ (Markdown: https://insights.sbomify.com/CVE-2024-50151/index.md)","id":"CVE-2024-50151","markdown":"https://insights.sbomify.com/CVE-2024-50151/index.md","name":"CVE-2024-50151","record":{"aliases":["AZL-53543","AZL-53733","BELL-CVE-2024-50151","DEBIAN-CVE-2024-50151","GHSA-g8wq-w697-wh26","UBUNTU-CVE-2024-50151"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel CIFS client","requires_auth":"low_privilege","summary":"A local attacker can trigger an out-of-bounds write in the Linux kernel CIFS client when using encrypted mounts, potentially causing a crash or code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: fix OOBs when building SMB2_IOCTL request\n\nWhen using encryption, either enforced by the server or when using\n'seal' mount option, the client will squash all compound request buffers\ndown for encryption into a single iov in smb2_set_next_command().\n\nSMB2_ioctl_init() allocates a small buffer (448 bytes) to hold the\nSMB2_IOCTL request in the first iov, and if the user passes an input\nbuffer that is greater than 328 bytes, smb2_set_next_command() will\nend up writing off the end of @rqst-\u003eiov[0].iov_base as shown below:\n\n  mount.cifs //srv/share /mnt -o ...,seal\n  ln -s $(perl -e \"print('a')for 1..1024\") /mnt/link\n\n  BUG: KASAN: slab-out-of-bounds in\n  smb2_set_next_command.cold+0x1d6/0x24c [cifs]\n  Write of size 4116 at addr ffff8881148fcab8 by task ln/859\n\n  CPU: 1 UID: 0 PID: 859 Comm: ln Not tainted 6.12.0-rc3 #1\n  Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS\n  1.16.3-2.fc40 04/01/2014\n  Call Trace:\n   \u003cTASK\u003e\n   dump_stack_lvl+0x5d/0x80\n   ?
