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-2026-53305 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-2026-53305/ (Markdown: https://insights.sbomify.com/CVE-2026-53305/index.md)","id":"CVE-2026-53305","markdown":"https://insights.sbomify.com/CVE-2026-53305/index.md","name":"CVE-2026-53305","record":{"aliases":["BELL-CVE-2026-53305","DEBIAN-CVE-2026-53305","GHSA-w4pj-2vvj-f3vp","UBUNTU-CVE-2026-53305"],"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 null pointer dereference in the Linux kernel ps883x driver causes a system crash when unbinding the device, leading to 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\nusb: typec: ps883x: Fix Oops at unbind\n\nWhen trying to unbind a device in order to bind to it vfio-platform as:\n\n  echo bc0000.geniqup  \u003e /sys/bus/platform/devices/bc0000.geniqup/driver/unbind\n\nI get the following Oops:\n\n[  436.478639] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020\n[  436.487762] Mem abort info:\n[  436.490716]   ESR = 0x0000000096000004\n[  436.494595]   EC = 0x25: DABT (current EL), IL = 32 bits\n[  436.500071]   SET = 0, FnV = 0\n[  436.503250]   EA = 0, S1PTW = 0\n[  436.506505]   FSC = 0x04: level 0 translation fault\n[  436.511533] Data abort info:\n[  436.514558]   ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000\n[  436.520215]   CM = 0, WnR = 0, TnD = 0, TagAccess = 0\n[  436.525436]   GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0\n[  436.530918] user pgtable: 4k pages, 48-bit VAs, pgdp=00000008861a9000\n[  436.537554] [0000000000000020] pgd=0000000000000000, p4d=0000000000000000\n[  436.544548] Internal error: Oops: 0000000096000004 [#1]  SMP\n[  436.550374] Modules linked in:\n[  436.553542] CPU: 2 UID: 0 PID: 671 Comm: bash Tainted: G        W           7.0.0-rc3-g56fcdd0911a5-dirty #2 PREEMPT\n[  436.564440] Tainted: [W]=WARN\n[  436.567515] Hardware name: LENOVO 91B6CTO1WW/3796, BIOS O6NKT3BA 05/02/2025\n[  436.574675] pstate: 21400005 (nzCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--)\n[  436.581841] pc : ps883x_retimer_remove+0x14/0x94\n[  436.586605] lr : i2c_device_remove+0x28/0x84\n[  436.591017] sp : ffff8000847137c0\n\nThat's because the ps883x_retimer_remove() retrieves the driver data\nfrom i2c_get_clientdata() which was never set at probe.
