The UAF was observed occurring naturally in the field via KFENCE, confirming the window is routinely hit.\nPR:L - SR-IOV VF assignment is the mainstream QAT deployment model, and a tenant guest or VFIO-granted user holding a QAT function can make it signal an uncorrectable error; `pci_walk_bridge()` then broadcasts `slot_reset` across the port's subordinate bus, invoking the host PF's `adf_slot_reset()` \u2014 no host root needed. Unprivileged local users can additionally drive arbitrary traffic through the device via AF_ALG, which dispatches to the QAT skcipher/aead implementations.\nUI:N - The reset worker and the timing-out caller both run entirely within kernel context once the PCIe error is signalled; no victim action, mount, or file open is required.\nS:U - The freed `adf_reset_dev_data` and the corruption caused by the stale `complete()` are both host kernel heap objects under the same security authority; no hypervisor, IOMMU, or sandbox boundary is itself bypassed by the flaw.\nC:H - The worker performs a use-after-free read of `reset_data->mode` and dereferences `x->wait.task_list` out of the freed ~80-byte `kmalloc-96` object, a cache an attacker can reliably reoccupy with sprayed objects (msg_msg, xattr, etc.), turning the stale reference into a controlled read of kernel memory.\nI:H - `complete()` on the freed object writes into it \u2014 taking a raw spinlock, incrementing `x->done`, and running `swake_up_locked()` over an attacker-groomed wait list, yielding `wake_up_process()` on a controlled task pointer; because `ADF_DEV_RESET_ASYNC == 0`, a zeroed reallocation of the slot also produces a second `kfree()` on the already-freed pointer, a classic double-free route to an arbitrary write.\nA:H - The use-after-free and potential double free corrupt the slab allocator, producing KASAN/KFENCE splats and kernel panics (immediate under `panic_on_warn`), and the reset path additionally hits `WARN(1, \"QAT: device restart failed. Device is unusable\")`, leaving the crypto accelerator dead."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "daba62d9eeddcc5b1081be7d348ca836c83c59d7", "versionType": "git"}, {"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "8e81cd58aee14a470891733181a47d123193ba81", "versionType": "git"}, {"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "d03092550f526a79cf1ade7f0dfa74906f39eb71", "versionType": "git"}, {"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "4ae5a97781ce7d6ecc9c7055396535815b64ca4f", "versionType": "git"}, {"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "226fc408c5fcd23cc4186f05ea3a09a7a9aef2f7", "versionType": "git"}, {"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "8a5a7611ccc7b1fba8d933a9f22a2e76859d94dc", "versionType": "git"}, {"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "0c2cf5142bfb634c0ef0a1a69cdf37950747d0be", "versionType": "git"}, {"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "bb279ead42263e9fb09480f02a4247b2c287d828", "versionType": "git"}, {"status": "affected", "version": "d8cba25d2c68992a6e7c1d329b690a9ebe01167d", "lessThan": "7d42e097607c4d246d99225bf2b195b6167a210c", "versionType": "git"}], "programFiles": ["drivers/crypto/intel/qat/qat_common/adf_aer.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "3.17"}, {"status": "unaffected", "version": "0", "lessThan": "3.17", "versionType": "semver"}, {"status": "unaffected", "version": "4.19.312", "versionType": "semver", "lessThanOrEqual": "4.19.*"}, {"status": "unaffected", "version": "5.4.274", "versionType": "semver", "lessThanOrEqual": "5.4.*"}, {"status": "unaffected", "version": "5.10.215", "versionType": "semver", "lessThanOrEqual": "5.10.*"}, {"status": "unaffected", "version": "5.15.154", "versionType": "semver", "lessThanOrEqual": "5.15.*"}, {"status": "unaffected", "version": "6.1.84", "versionType": "semver", "lessThanOrEqual": "6.1.*"}, {"status": "unaffected", "version": "6.6.24", "versionType": "semver", "lessThanOrEqual": "6.6.*"}, {"status": "unaffected", "version": "6.7.12", "versionType": "semver", "lessThanOrEqual": "6.7.*"}, {"status": "unaffected", "version": "6.8.3", "versionType": "semver", "lessThanOrEqual": "6.8.*"}, {"status": "unaffected", "version": "6.9", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["drivers/crypto/intel/qat/qat_common/adf_aer.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/daba62d9eeddcc5b1081be7d348ca836c83c59d7"}, {"url": "https://git.kernel.org/stable/c/8e81cd58aee14a470891733181a47d123193ba81"}, {"url": "https://git.kernel.org/stable/c/d03092550f526a79cf1ade7f0dfa74906f39eb71"}, {"url": "https://git.kernel.org/stable/c/4ae5a97781ce7d6ecc9c7055396535815b64ca4f"}, {"url": "https://git.kernel.org/stable/c/226fc408c5fcd23cc4186f05ea3a09a7a9aef2f7"}, {"url": "https://git.kernel.org/stable/c/8a5a7611ccc7b1fba8d933a9f22a2e76859d94dc"}, {"url": "https://git.kernel.org/stable/c/0c2cf5142bfb634c0ef0a1a69cdf37950747d0be"}, {"url": "https://git.kernel.org/stable/c/bb279ead42263e9fb09480f02a4247b2c287d828"}, {"url": "https://git.kernel.org/stable/c/7d42e097607c4d246d99225bf2b195b6167a210c"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: qat - resolve race condition during AER recovery\n\nDuring the PCI AER system's error recovery process, the kernel driver\nmay encounter a race condition with freeing the reset_data structure's\nmemory.
