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-2023-53349 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-2023-53349/ (Markdown: https://insights.sbomify.com/CVE-2023-53349/index.md)","id":"CVE-2023-53349","markdown":"https://insights.sbomify.com/CVE-2023-53349/index.md","name":"CVE-2023-53349","record":{"aliases":["BELL-CVE-2023-53349","DEBIAN-CVE-2023-53349","GHSA-8g4h-m7m7-62x8","UBUNTU-CVE-2023-53349"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A memory leak in the ov2740 camera driver allows attackers to exhaust kernel memory, potentially causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: ov2740: Fix memleak in ov2740_init_controls()\n\nThere is a kmemleak when testing the media/i2c/ov2740.c with bpf mock\ndevice:\n\nunreferenced object 0xffff8881090e19e0 (size 16):\n  comm \"51-i2c-ov2740\", pid 278, jiffies 4294781584 (age 23.613s)\n  hex dump (first 16 bytes):\n    00 f3 7c 0b 81 88 ff ff 80 75 6a 09 81 88 ff ff  ..|......uj.....\n  backtrace:\n    [\u003c000000004e9fad8f\u003e] __kmalloc_node+0x44/0x1b0\n    [\u003c0000000039c802f4\u003e] kvmalloc_node+0x34/0x180\n    [\u003c000000009b8b5c63\u003e] v4l2_ctrl_handler_init_class+0x11d/0x180\n[videodev]\n    [\u003c0000000038644056\u003e] ov2740_probe+0x37d/0x84f [ov2740]\n    [\u003c0000000092489f59\u003e] i2c_device_probe+0x28d/0x680\n    [\u003c000000001038babe\u003e] really_probe+0x17c/0x3f0\n    [\u003c0000000098c7af1c\u003e] __driver_probe_device+0xe3/0x170\n    [\u003c00000000e1b3dc24\u003e] device_driver_attach+0x34/0x80\n    [\u003c000000005a04a34d\u003e] bind_store+0x10b/0x1a0\n    [\u003c00000000ce25d4f2\u003e] drv_attr_store+0x49/0x70\n    [\u003c000000007d9f4e9a\u003e] sysfs_kf_write+0x8c/0xb0\n    [\u003c00000000be6cff0f\u003e] kernfs_fop_write_iter+0x216/0x2e0\n    [\u003c0000000031ddb40a\u003e] vfs_write+0x658/0x810\n    [\u003c0000000041beecdd\u003e] ksys_write+0xd6/0x1b0\n    [\u003c0000000023755840\u003e] do_syscall_64+0x38/0x90\n    [\u003c00000000b2cc2da2\u003e] entry_SYSCALL_64_after_hwframe+0x63/0xcd\n\nov2740_init_controls() won't clean all the allocated resources in fail\npath, which may causes the memleaks.
