Title
drm: adv7511: Fix use-after-free in adv7533_attach_dsi()
Summary
In the Linux kernel, the following vulnerability has been resolved: drm: adv7511: Fix use-after-free in adv7533_attach_dsi() The host_node pointer was assigned and freed in adv7533_parse_dt(), and later, adv7533_attach_dsi() uses the same. Fix this use-after-free issue by dropping of_node_put() in adv7533_parse_dt() and calling of_node_put() in error path of probe() and also in the remove().

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\u0027d 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 \u2014 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."

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\u0027d 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 \\u2014 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\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"1e4d58cd7f888522d16f221d628356befbb08468\", \"lessThan\": \"acec80d9f126cd3fa764bbe3d96bc0cb5cd2b087\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1e4d58cd7f888522d16f221d628356befbb08468\", \"lessThan\": \"d208571943ffddc438a7ce533d5d0b9219806242\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1e4d58cd7f888522d16f221d628356befbb08468\", \"lessThan\": \"1f49aaf55652580ae63ab83d67211fe6a55d83dc\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1e4d58cd7f888522d16f221d628356befbb08468\", \"lessThan\": \"ca9d077350fa21897de8bf64cba23b198740aab5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1e4d58cd7f888522d16f221d628356befbb08468\", \"lessThan\": \"81adbd3ff21c1182e06aa02c6be0bfd9ea02d8e8\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/gpu/drm/bridge/adv7511/adv7511_drv.c\", \"drivers/gpu/drm/bridge/adv7511/adv7533.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.8\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.8\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.234\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.125\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.70\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.9\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.13\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/gpu/drm/bridge/adv7511/adv7511_drv.c\", \"drivers/gpu/drm/bridge/adv7511/adv7533.c\"], \"defaultStatus\": \"affected\"}], \"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\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ndrm: adv7511: Fix use-after-free in adv7533_attach_dsi()\\n\\nThe host_node pointer was assigned and freed in adv7533_parse_dt(), and\\nlater, adv7533_attach_dsi() uses the same.
