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-2022-50295 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-2022-50295/ (Markdown: https://insights.sbomify.com/CVE-2022-50295/index.md)","id":"CVE-2022-50295","markdown":"https://insights.sbomify.com/CVE-2022-50295/index.md","name":"CVE-2022-50295","record":{"aliases":["DEBIAN-CVE-2022-50295","GHSA-pwv6-q4qx-8vf8","UBUNTU-CVE-2022-50295"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel crash via a NULL pointer dereference in the io_uring subsystem, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"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-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring/msg_ring: Fix NULL pointer dereference in io_msg_send_fd()\n\nSyzkaller produced the below call trace:\n\n BUG: KASAN: null-ptr-deref in io_msg_ring+0x3cb/0x9f0\n Write of size 8 at addr 0000000000000070 by task repro/16399\n\n CPU: 0 PID: 16399 Comm: repro Not tainted 6.1.0-rc1 #28\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.11.0-2.el7\n Call Trace:\n  \u003cTASK\u003e\n  dump_stack_lvl+0xcd/0x134\n  ?
