Vulnerability from cvelistv5
Published

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: dmaengine: Fix possible use after free In dma_release_channel(), check chan->device->privatecnt after call dma_chan_put(). However, dma_chan_put() call dma_device_put() which could release the last reference of the device if the DMA provider is already gone and hence free it. Fixes it by moving dma_chan_put() after the check.

when the DMA provider has already unregistered via unbind, hot-unplug, or module teardown, dma_chan_put() frees dma_device and the subsequent privatecnt access is a reliably triggerable UAF with attacker-controlled release timing.\\nPR:L - Exploitation requires only a local unprivileged process able to open a device whose driver uses dma_request_chan() or dma_request_channel(); on embedded ADI FPGA, Android, and industrial platforms, non-root application users commonly have such device-node access without init-namespace root or CAP_SYS_ADMIN.\\nUI:N - No victim interaction is required beyond the attacker opening, holding, and closing their own device handle or racing driver teardown; no other user must mount filesystems, approve prompts, or perform separate actions for exploitation to succeed.\\nS:U - This is a kernel slab use-after-free in the dmaengine channel-release path affecting the same kernel security authority; it does not cross VM, IOMMU, container, or other sandbox boundaries and is standard in-kernel memory corruption rather than a scope change.\\nC:H - After dma_chan_put() frees the last dma_device kref, the code reads and decrements privatecnt and may clear cap_mask on freed kmalloc memory; UAF on dma_device objects enables disclosure of attacker-influenced freed-heap contents per kernel UAF scoring guidance.\\nI:H - Post-free modification of privatecnt and cap_mask corrupts reused slab objects under attacker influence, providing a plausible kernel heap corruption path toward arbitrary write primitives, control-flow hijacking, or local privilege escalation.\\nA:H - Dereferencing freed dma_device memory during dma_release_channel() can cause KASAN slab-use-after-free reports, kernel oops, BUG, or panic; kernel guidance treats any use-after-free as high availability impact even when full exploitation is not demonstrated.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"0f571515c332e00b3515dbe0859ceaa30ab66e00\", \"lessThan\": \"444f96066937f3fdf0e79b53289cff223c7d638b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0f571515c332e00b3515dbe0859ceaa30ab66e00\", \"lessThan\": \"ab438a9efb9042c79d2f8db28a326d55feb8591f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0f571515c332e00b3515dbe0859ceaa30ab66e00\", \"lessThan\": \"9bdc8dce4068dadbdf7cf5ad6d4983e2afffedce\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0f571515c332e00b3515dbe0859ceaa30ab66e00\", \"lessThan\": \"5876f38b67a309c00628942cb25679749b53b397\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0f571515c332e00b3515dbe0859ceaa30ab66e00\", \"lessThan\": \"3b0240483dc977dbec4f3bc7a5383d4691ecb625\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0f571515c332e00b3515dbe0859ceaa30ab66e00\", \"lessThan\": \"329ec20a86091d2a6e5b4fe507545e7d678a22a2\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0f571515c332e00b3515dbe0859ceaa30ab66e00\", \"lessThan\": \"0bc191050c3253da8ef4bfaf157c44efed6e22cd\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"0f571515c332e00b3515dbe0859ceaa30ab66e00\", \"lessThan\": \"92f853f0645aebf1d05d333e97ab7c342ace1892\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/dma/dmaengine.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"2.6.30\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"2.6.30\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.261\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.212\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.178\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.145\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.97\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.40\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/dma/dmaengine.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/444f96066937f3fdf0e79b53289cff223c7d638b\"}, {\"url\": \"https://git.kernel.org/stable/c/ab438a9efb9042c79d2f8db28a326d55feb8591f\"}, {\"url\": \"https://git.kernel.org/stable/c/9bdc8dce4068dadbdf7cf5ad6d4983e2afffedce\"}, {\"url\": \"https://git.kernel.org/stable/c/5876f38b67a309c00628942cb25679749b53b397\"}, {\"url\": \"https://git.kernel.org/stable/c/3b0240483dc977dbec4f3bc7a5383d4691ecb625\"}, {\"url\": \"https://git.kernel.org/stable/c/329ec20a86091d2a6e5b4fe507545e7d678a22a2\"}, {\"url\": \"https://git.kernel.org/stable/c/0bc191050c3253da8ef4bfaf157c44efed6e22cd\"}, {\"url\": \"https://git.kernel.org/stable/c/92f853f0645aebf1d05d333e97ab7c342ace1892\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ndmaengine: Fix possible use after free\\n\\nIn dma_release_channel(), check chan-\u003edevice-\u003eprivatecnt after call\\ndma_chan_put().
