Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: tee: optee: Fix incorrect page free bug Pointer to the allocated pages (struct page *page) has already progressed towards the end of allocation. It is incorrect to perform __free_pages(page, order) using this pointer as we would free any arbitrary pages. Fix this by stop modifying the page pointer.

not exposed over the network.\\nAC:L - An attacker who can open the TEE client device can reliably force the shm_register failure path (e.g., by exhausting OP-TEE dynamic SHM registration capacity or inducing allocation failure after alloc_pages succeeds), which triggers the incorrect __free_pages().\\nPR:L - /dev/tee0 is the unprivileged client interface with no capability check in the driver; access is DAC-only and commonly granted to non-root teeclnt/group users or TEE client apps on Android/embedded deployments.\\nUI:N - Exploitation requires only opening the device and issuing TEE_IOC_SHM_ALLOC; no victim action is needed.\\nS:U - The incorrect free corrupts Normal-World kernel memory within the same OS security authority; this is standard local kernel privilege escalation, not a TrustZone/VM boundary escape.\\nC:H - __free_pages() on the advanced page pointer frees unrelated in-use pages, enabling use-after-free of attacker-influenced heap objects and arbitrary kernel memory disclosure.\\nI:H - Arbitrary page free yields classic UAF/heap corruption primitives that can be turned into arbitrary write and control-flow hijacking in the kernel.\\nA:H - Freeing pages still owned by other kernel allocations causes oops/panic or allocator corruption and can crash the system even without a full exploit.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"3c712f14d8a9354a8807c15c64c8dd334499cc42\", \"lessThan\": \"806142c805cacd098e61bdc0f72c778a2389fe4a\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"1340dc3fb75ea69221f4f5dcb0cbace55ad0331c\", \"lessThan\": \"ad338d825e3f7b96ee542bf313728af2d19fe9ad\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ec185dd3ab257dc2a60953fdf1b6622f524cc5b7\", \"lessThan\": \"91e94e42f6fc49635f1a16d8ae3f79552bcfda29\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"ec185dd3ab257dc2a60953fdf1b6622f524cc5b7\", \"lessThan\": \"18549bf4b21c739a9def39f27dcac53e27286ab5\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"255e17923b22cb7abd026e044416d61f6bd0eec0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5.4.140\", \"lessThan\": \"5.4.169\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"5.10.58\", \"lessThan\": \"5.10.89\", \"versionType\": \"semver\"}, {\"status\": \"affected\", \"version\": \"5.13.10\", \"lessThan\": \"5.14\", \"versionType\": \"semver\"}], \"programFiles\": [\"drivers/tee/optee/core.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.14\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.14\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.4.169\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.89\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.12\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"5.16\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/tee/optee/core.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/806142c805cacd098e61bdc0f72c778a2389fe4a\"}, {\"url\": \"https://git.kernel.org/stable/c/ad338d825e3f7b96ee542bf313728af2d19fe9ad\"}, {\"url\": \"https://git.kernel.org/stable/c/91e94e42f6fc49635f1a16d8ae3f79552bcfda29\"}, {\"url\": \"https://git.kernel.org/stable/c/18549bf4b21c739a9def39f27dcac53e27286ab5\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ntee: optee: Fix incorrect page free bug\\n\\nPointer to the allocated pages (struct page *page) has already\\nprogressed towards the end of allocation.
