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-2022-50272 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-2022-50272/ (Markdown: https://insights.sbomify.com/CVE-2022-50272/index.md)","id":"CVE-2022-50272","markdown":"https://insights.sbomify.com/CVE-2022-50272/index.md","name":"CVE-2022-50272","record":{"aliases":["DEBIAN-CVE-2022-50272","GHSA-q5mm-hfp5-3xxh","UBUNTU-CVE-2022-50272"],"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 null pointer dereference in the Linux kernel's az6027 USB driver allows local attackers to cause a system crash via crafted I2C ioctl calls.","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\nmedia: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()\n\nWei Chen reports a kernel bug as blew:\n\ngeneral protection fault, probably for non-canonical address\nKASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017]\n...\nCall Trace:\n\u003cTASK\u003e\n__i2c_transfer+0x77e/0x1930 drivers/i2c/i2c-core-base.c:2109\ni2c_transfer+0x1d5/0x3d0 drivers/i2c/i2c-core-base.c:2170\ni2cdev_ioctl_rdwr+0x393/0x660 drivers/i2c/i2c-dev.c:297\ni2cdev_ioctl+0x75d/0x9f0 drivers/i2c/i2c-dev.c:458\nvfs_ioctl fs/ioctl.c:51 [inline]\n__do_sys_ioctl fs/ioctl.c:870 [inline]\n__se_sys_ioctl+0xfb/0x170 fs/ioctl.c:856\ndo_syscall_x64 arch/x86/entry/common.c:50 [inline]\ndo_syscall_64+0x3d/0x90 arch/x86/entry/common.c:80\nentry_SYSCALL_64_after_hwframe+0x63/0xcd\nRIP: 0033:0x7fd834a8bded\n\nIn az6027_i2c_xfer(), if msg[i].addr is 0x99,\na null-ptr-deref will caused when accessing msg[i].buf.\nFor msg[i].len is 0 and msg[i].buf is null.\n\nFix this by checking msg[i].len in az6027_i2c_xfer().","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()","id":"CVE-2022-50272","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2022"},"n_packages":0,"n_references":9,"next":{"headline":"f2fs: fix to do sanity check on destination blkaddr during recovery","id":"CVE-2022-50273"},"packages":[],"prev":{"headline":"vhost/vsock: Use kvmalloc/kvfree for larger packets.","id":"CVE-2022-50271"},"products":["Linux"],"published":"2025-09-15","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel's az6027 USB driver allows local attackers to cause a system crash via crafted I2C ioctl calls.","url":"https://insights.sbomify.com/CVE-2022-50272/"}
