Exploitation requires local system access via syscalls/ioctls on those device files.\nAC:L - The attacker controls both sides of the race: the drain-loop side is widened arbitrarily (seconds) by selecting a slow baud rate so the peer PDMA lags, and the terminate side is fired on demand via `tcflush()`, which reaches `dmaengine_terminate_async()` \u2192 `udma_terminate_all()`'s non-synchronous `cancel_delayed_work()`. The sequence is freely repeatable until it lands.\nPR:L - Only an unprivileged account with access to a device node backed by a UDMA channel is needed \u2014 a tty (dialout/owning session), `/dev/snd/pcm*` (audio group), or spidev \u2014 all routinely granted to non-root users on the embedded, industrial, and automotive K3 deployments this driver targets. No capability check gates the path.\nUI:N - The attacker's own `write()`/`ioctl(TCFLSH)` sequence on a device it already has open drives the entire race. No victim action or cooperation is involved.\nS:U - The corruption is confined to kernel heap objects and virt-dma lists within the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The unlocked worker dereferences a `struct udma_desc` that `vchan_dma_desc_free_list()`/`udma_purge_desc_work()` may have already `kfree()`d, and traverses spliced list heads \u2014 a use-after-free that lets a groomed replacement object be read back, yielding arbitrary kernel memory disclosure.\nI:H - `list_del()` in `udma_start()` and `list_add_tail()` in `vchan_cookie_complete()` execute unlocked against concurrently spliced and freed nodes, giving classic doubly-linked-list corruption plus writes through a stale descriptor in `udma_decrement_byte_counters()` \u2014 a controllable write primitive suitable for control-flow hijack.\nA:H - Even unweaponized, the use-after-free and list corruption reliably produce oopses, double-frees, and slab corruption panics; the concurrent double `udma_start()` from worker and IRQ handler also wedges the DMA channel."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/dma/ti/k3-udma.c"], "versions": [{"version": "25dcb5dd7b7ce5587c1df18f584ff78f51a68a94", "lessThan": "27e71fa08711e09d81e06a54007b362a5426fd22", "status": "affected", "versionType": "git"}, {"version": "25dcb5dd7b7ce5587c1df18f584ff78f51a68a94", "lessThan": "0ea0433f822ed0549715f7044c9cd1cf132ff7fa", "status": "affected", "versionType": "git"}, {"version": "25dcb5dd7b7ce5587c1df18f584ff78f51a68a94", "lessThan": "df5987e76a4ae4cbd705d81ab4b15ed232250a4a", "status": "affected", "versionType": "git"}, {"version": "25dcb5dd7b7ce5587c1df18f584ff78f51a68a94", "lessThan": "d87f1cddc592387359fde157cc4296556f6403c2", "status": "affected", "versionType": "git"}, {"version": "25dcb5dd7b7ce5587c1df18f584ff78f51a68a94", "lessThan": "26e63b2fe30c61bd25981c6084f67a8af79945d0", "status": "affected", "versionType": "git"}, {"version": "25dcb5dd7b7ce5587c1df18f584ff78f51a68a94", "lessThan": "99df1edf17493cb49a8c01f6bde55c3abb6a2a6c", "status": "affected", "versionType": "git"}, {"version": "25dcb5dd7b7ce5587c1df18f584ff78f51a68a94", "lessThan": "fca280992af8c2fbd511bc43f65abb4a17363f2f", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/dma/ti/k3-udma.c"], "versions": [{"version": "5.6", "status": "affected"}, {"version": "0", "lessThan": "5.6", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.238", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.184", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.140", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.92", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.30", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.14.8", "lessThanOrEqual": "6.14.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.15", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.6", "versionEndExcluding": "5.10.238"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.6", "versionEndExcluding": "5.15.184"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.6", "versionEndExcluding": "6.1.140"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.6", "versionEndExcluding": "6.6.92"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.6", "versionEndExcluding": "6.12.30"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.6", "versionEndExcluding": "6.14.8"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.6", "versionEndExcluding": "6.15"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/27e71fa08711e09d81e06a54007b362a5426fd22"}, {"url": "https://git.kernel.org/stable/c/0ea0433f822ed0549715f7044c9cd1cf132ff7fa"}, {"url": "https://git.kernel.org/stable/c/df5987e76a4ae4cbd705d81ab4b15ed232250a4a"}, {"url": "https://git.kernel.org/stable/c/d87f1cddc592387359fde157cc4296556f6403c2"}, {"url": "https://git.kernel.org/stable/c/26e63b2fe30c61bd25981c6084f67a8af79945d0"}, {"url": "https://git.kernel.org/stable/c/99df1edf17493cb49a8c01f6bde55c3abb6a2a6c"}, {"url": "https://git.kernel.org/stable/c/fca280992af8c2fbd511bc43f65abb4a17363f2f"}], "title": "dmaengine: ti: k3-udma: Add missing locking", "x_generator": {"engine": "bippy-1.2.0"}}, "adp": [{"title": "CVE Program Container", "references": [{"url": "https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"}, {"url": "https://lists.debian.org/debian-lts-announce/2025/08/msg00010.html"}], "providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T19:58:13.689Z"}}]}}
