Title
io_uring/rw: split io_read() into a helper
Summary
In the Linux kernel, the following vulnerability has been resolved:
IORING_OP_READ did not correctly consume the provided buffer list when
read i/o returned < 0 (except for -EAGAIN and -EIOCBQUEUED return).
This can lead to a potential use-after-free when the completion via
io_rw_done runs at separate context.
Severity

any race with async io_rw_done task-work is attacker-controlled.\\nPR:L - io_uring is usable by unprivileged users by default (sysctl kernel.io_uring_disabled=0); no CAP_SYS_ADMIN or init-namespace root is required.\\nUI:N - The attacker submits their own io_uring SQEs and provided buffers; no victim action is required.\\nS:U - This is kernel memory corruption within the host kernel\u0027s authority (local privilege escalation), not a VM escape or IOMMU/security-boundary crossover.\\nC:H - CVE documents a use-after-free on provided buffer list mishandling; UAF enables control of freed object contents and arbitrary kernel memory disclosure.\\nI:H - Kernel UAF on provided buffers is exploitable for heap reuse and arbitrary write/control-flow hijacking, enabling privilege escalation.\\nA:H - Use-after-free in io_uring completion can cause kernel oops/panic even when not fully exploited for code execution.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"2b188cc1bb857a9d4701ae59aa7768b5124e262e\", \"lessThan\": \"72060434a14caea20925e492310d6e680e3f9007\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"2b188cc1bb857a9d4701ae59aa7768b5124e262e\", \"lessThan\": \"6c27fc6a783c8a77c756dd5461b15e465020d075\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"2b188cc1bb857a9d4701ae59aa7768b5124e262e\", \"lessThan\": \"a08d195b586a217d76b42062f88f375a3eedda4d\", \"versionType\": \"git\"}], \"programFiles\": [\"io_uring/rw.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.1\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.1\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.122\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.68\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"io_uring/rw.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/72060434a14caea20925e492310d6e680e3f9007\"}, {\"url\": \"https://git.kernel.org/stable/c/6c27fc6a783c8a77c756dd5461b15e465020d075\"}, {\"url\": \"https://git.kernel.org/stable/c/a08d195b586a217d76b42062f88f375a3eedda4d\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nIORING_OP_READ did not correctly consume the provided buffer list when\\nread i/o returned \u003c 0 (except for -EAGAIN and -EIOCBQUEUED return).\\nThis can lead to a potential use-after-free when the completion via\\nio_rw_done runs at separate context.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.122\", \"versionStartIncluding\": \"5.1\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.68\", \"versionStartIncluding\": \"5.1\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.7\", \"versionStartIncluding\": \"5.1\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-05T09:12:04.609Z\"}}}",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
