Exploitation requires local interaction with the platform-driver lifecycle or subsequent local use of the dangling kernel objects.\nAC:L - On an affected non-OF deployment, probe-error cleanup or driver removal deterministically drops a reference that was never acquired. No race must be won, and heap reclaim can be attacker-groomed.\nPR:L - Although manual unbind or module removal requires init-namespace administration, the same release occurs during automatic probe-failure cleanup. A basic local user can groom and exercise the resulting published dangling I2C and USB-PHY objects.\nUI:N - Probe and cleanup can occur automatically without a victim performing an action. Subsequent exploitation of the dangling objects requires no user interaction.\nS:U - The corruption affects the kernel and resources governed by the same system security authority. It does not cross a VM, IOMMU, or comparable isolation boundary.\nC:H - The release frees the I2C client and devres-managed ISP1301 object while global pointers and I2C and USB-PHY lists still reference them. Reclaiming these objects can expose arbitrary kernel memory through attacker-shaped stale pointers.\nI:H - Dangling klist operations can modify reclaimed memory, while a reclaimed client can supply a forged adapter and indirect I2C algorithm callbacks. This can provide arbitrary writes and kernel control-flow hijacking.\nA:H - Traversal or use of the dangling client, device-private nodes, or USB-PHY list entry can cause an immediate kernel oops, panic, or invalid function call." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/usb/phy/phy-isp1301.c" ], "versions": [ { "version": "0c2b0e747010fa645342138d71339a0ecb823bb0", "lessThan": "43e58abad6c08c5f0943594126ef4cd6559aac0b", "status": "affected", "versionType": "git" }, { "version": "33c2e2a87313bc1afe9f7febbbb2014c431a2c5d", "lessThan": "03bbdaa4da8c6ea0c8431a5011db188a07822c8a", "status": "affected", "versionType": "git" }, { "version": "8481323710062051b3c42bff94ee5b18a2b496ca", "lessThan": "75c5d9bce072abbbc09b701a49869ac23c34a906", "status": "affected", "versionType": "git" }, { "version": "8bd518ea03b81eb7b4a734b7b901866c448f6c07", "lessThan": "5d3df03f70547d4e3fc10ed4381c052eff51b157", "status": "affected", "versionType": "git" }, { "version": "cefaad839a384a72331aedad927b1944fb6943dc", "lessThan": "7501ecfe3e5202490c2d13dc7e181203601fcd69", "status": "affected", "versionType": "git" }, { "version": "c84117912bddd9e5d87e68daf182410c98181407", "lessThan": "b4b64fda4d30a83a7f00e92a0c8a1d47699609f3", "status": "affected", "versionType": "git" }, { "version": "21c7c83d592e6335bfb6d65608da3726f976bad4", "status": "affected", "versionType": "git" }, { "version": "5.10.248", "lessThan": "5.11", "status": "affected", "versionType": "semver" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/usb/phy/phy-isp1301.c" ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10.248" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/43e58abad6c08c5f0943594126ef4cd6559aac0b" }, { "url": "https://git.kernel.org/stable/c/03bbdaa4da8c6ea0c8431a5011db188a07822c8a" }, { "url": "https://git.kernel.org/stable/c/75c5d9bce072abbbc09b701a49869ac23c34a906" }, { "url": "https://git.kernel.org/stable/c/5d3df03f70547d4e3fc10ed4381c052eff51b157" }, { "url": "https://git.kernel.org/stable/c/7501ecfe3e5202490c2d13dc7e181203601fcd69" }, { "url": "https://git.kernel.org/stable/c/b4b64fda4d30a83a7f00e92a0c8a1d47699609f3" } ], "title": "usb: phy: isp1301: fix non-OF device reference imbalance", "x_generator": { "engine": "bippy-1.2.0" } } } }
