Physical access to the soldered ADV7533/ADV7535 confers no additional capability, so Local is the correct and higher-severity vector.\nAC:L - There is no race to win: dropping the reference in adv7533_parse_dt() deterministically permits the backing device_node to be freed, and the attacker drives both the free (overlay removal / detach) and the subsequent use (probe or probe-deferral retry of adv7533_attach_dsi()). Repeated bind/unbind cycles and the -EPROBE_DEFER retry loop let the attacker groom the freed kmalloc slab at will.\nPR:L - Neither adv7511_probe(), adv7533_parse_dt(), nor adv7533_attach_dsi() contains any capable()/CAP_* gate; access is governed solely by file permissions on the sysfs/configfs device-management nodes, which on the embedded, industrial and automotive ARM64 platforms where ADV7533/ADV7535 is deployed are routinely delegated to non-root device-manager and display service accounts. Real root in the initial namespace is not required.\nUI:N - The attacker triggers the sequence entirely on their own by driving the overlay/bind cycle; the stale pointer is also consumed automatically on every boot-time deferred-probe retry. No victim action, mount, or file open is involved.\nS:U - The freed struct device_node, the DSI host list, and the resulting corruption all live in the kernel of the same system under a single security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free of a kmalloc'd struct device_node in a general-purpose slab cache, so the attacker can reallocate the freed object with controlled content and steer the of_find_mipi_dsi_host_by_node() match and the ensuing mipi_dsi device registration. That yields disclosure of kernel pointers and adjacent slab contents, and UAF is scored High.\nI:H - Once the node is freed and its address reused, the pointer comparison can alias a different live DSI host, causing the bridge to register and attach against the wrong mipi_dsi_host — a type-confused attachment that programs the wrong hardware and writes through mismatched structures. The freed slab object additionally provides the write target that makes UAFs exploitable for control-flow hijacking.\nA:H - Using the dangling device_node after the overlay teardown produces a KASAN slab-use-after-free and an oops-class fault (panic with panic_on_warn), and a mis-attached DSI device leaves the display pipeline dead. The attacker can repeat the bind/unbind or overlay cycle indefinitely." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/bridge/adv7511/adv7511_drv.c", "drivers/gpu/drm/bridge/adv7511/adv7533.c" ], "versions": [ { "version": "1e4d58cd7f888522d16f221d628356befbb08468", "lessThan": "acec80d9f126cd3fa764bbe3d96bc0cb5cd2b087", "status": "affected", "versionType": "git" }, { "version": "1e4d58cd7f888522d16f221d628356befbb08468", "lessThan": "d208571943ffddc438a7ce533d5d0b9219806242", "status": "affected", "versionType": "git" }, { "version": "1e4d58cd7f888522d16f221d628356befbb08468", "lessThan": "1f49aaf55652580ae63ab83d67211fe6a55d83dc", "status": "affected", "versionType": "git" }, { "version": "1e4d58cd7f888522d16f221d628356befbb08468", "lessThan": "ca9d077350fa21897de8bf64cba23b198740aab5", "status": "affected", "versionType": "git" }, { "version": "1e4d58cd7f888522d16f221d628356befbb08468", "lessThan": "81adbd3ff21c1182e06aa02c6be0bfd9ea02d8e8", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/bridge/adv7511/adv7511_drv.c", "drivers/gpu/drm/bridge/adv7511/adv7533.c" ], "versions": [ { "version": "4.8", "status": "affected" }, { "version": "0", "lessThan": "4.8", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.234", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.125", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.70", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.9", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.13", "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": "4.8", "versionEndExcluding": "5.10.234" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.8", "versionEndExcluding": "6.1.125" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.8", "versionEndExcluding": "6.6.70" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.8", "versionEndExcluding": "6.12.9" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.8", "versionEndExcluding": "6.13" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/acec80d9f126cd3fa764bbe3d96bc0cb5cd2b087" }, { "url": "https://git.kernel.org/stable/c/d208571943ffddc438a7ce533d5d0b9219806242" }, { "url": "https://git.kernel.org/stable/c/1f49aaf55652580ae63ab83d67211fe6a55d83dc" }, { "url": "https://git.kernel.org/stable/c/ca9d077350fa21897de8bf64cba23b198740aab5" }, { "url": "https://git.kernel.org/stable/c/81adbd3ff21c1182e06aa02c6be0bfd9ea02d8e8" } ], "title": "drm: adv7511: Fix use-after-free in adv7533_attach_dsi()", "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-2024-57887", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "version": "2.0.3", "timestamp": "2025-02-11T15:41:02.098939Z" } } } ], "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": "2025-02-11T15:45:19.886Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html" }, { "url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T20:54:56.908Z" } } ] } }
