The bug is reached via DRM ioctls (DRM_IOCTL_PANFROST_SUBMIT) and close() on the Panfrost render node (/dev/dri/renderD*), which requires local process access to the device file rather than network or adjacent-network input.\nAC:L - An attacker controls both sides by submitting GPU jobs then closing the FD; panfrost_postclose frees file_priv while in-flight/hard-stopped jobs still dereference it on the IRQ completion path, and the author reproduced the UAF splat without depending on uncontrolled conditions.\nPR:L - Panfrost ioctls are marked DRM_RENDER_ALLOW on a render node that grants GPU access to unprivileged clients (e.g., Android apps or desktop users with render-node access) without root or DRM master authentication.\nUI:N - The attacker opens the render node, submits jobs, and closes their own FD; no separate victim action is required.\nS:U - Impact is confined to the host kernel authority (heap UAF / potential local privilege escalation); this is not a VM escape or IOMMU/DMA security-boundary bypass.\nC:H - Use-after-free of panfrost_file_priv lets an attacker reclaim the object and corrupt the mmu pointer used by panfrost_mmu_as_get/put, enabling arbitrary kernel memory disclosure per UAF exploitation guidance.\nI:H - The same reclaimed file_priv/MMU pointer is consumed by job submit and IRQ completion paths that mutate MMU address-space state, yielding a controllable write/control-flow primitive suitable for integrity compromise and code execution.\nA:H - Dereferencing the freed file_priv causes a kernel oops/splat (as reported by the fix author) and can panic or hang the system, which is High availability impact." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/panfrost/panfrost_drv.c", "drivers/gpu/drm/panfrost/panfrost_job.c", "drivers/gpu/drm/panfrost/panfrost_job.h" ], "versions": [ { "version": "7fdc48cc63a30fa3480d18bdd8c5fff2b9b15212", "lessThan": "8c8e8cc91a6ffc79865108279a74fd57d9070a17", "status": "affected", "versionType": "git" }, { "version": "7fdc48cc63a30fa3480d18bdd8c5fff2b9b15212", "lessThan": "472dd7ea5e19a1aeabf1711ddc756777e05ee7c2", "status": "affected", "versionType": "git" }, { "version": "7fdc48cc63a30fa3480d18bdd8c5fff2b9b15212", "lessThan": "6e516faf04317db2c46cbec4e3b78b4653a5b109", "status": "affected", "versionType": "git" }, { "version": "c29485e34e63198dca6289639aa711f99d88e76e", "status": "affected", "versionType": "git" }, { "version": "626adede2642f00c8918999a2451bd0a644ab9b7", "status": "affected", "versionType": "git" }, { "version": "cf461fa9250a634e8afc4433d82ae0decea8136e", "status": "affected", "versionType": "git" }, { "version": "5.10.67", "lessThan": "5.11", "status": "affected", "versionType": "semver" }, { "version": "5.13.19", "lessThan": "5.14", "status": "affected", "versionType": "semver" }, { "version": "5.14.6", "lessThan": "5.15", "status": "affected", "versionType": "semver" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/panfrost/panfrost_drv.c", "drivers/gpu/drm/panfrost/panfrost_job.c", "drivers/gpu/drm/panfrost/panfrost_job.h" ], "versions": [ { "version": "5.15", "status": "affected" }, { "version": "0", "lessThan": "5.15", "status": "unaffected", "versionType": "semver" }, { "version": "5.17.15", "lessThanOrEqual": "5.17.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.18.4", "lessThanOrEqual": "5.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.19", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "5.17.15" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "5.18.4" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "5.19" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10.67" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.13.19" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.14.6" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/8c8e8cc91a6ffc79865108279a74fd57d9070a17" }, { "url": "https://git.kernel.org/stable/c/472dd7ea5e19a1aeabf1711ddc756777e05ee7c2" }, { "url": "https://git.kernel.org/stable/c/6e516faf04317db2c46cbec4e3b78b4653a5b109" } ], "title": "drm/panfrost: Job should reference MMU not file_priv", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 7.8, "attackVector": "LOCAL", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH" } }, { "other": { "type": "ssvc", "content": { "id": "CVE-2022-49359", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "version": "2.0.3", "timestamp": "2025-02-27T18:16:38.134749Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-416", "description": "CWE-416 Use After Free" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-02-27T18:22:33.808Z" } } ] } }
