Title
dmaengine: ti: k3-udma-glue: Fix of_k3_udma_glue_parse_chn_by_id()
Summary
In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma-glue: Fix of_k3_udma_glue_parse_chn_by_id() The of_k3_udma_glue_parse_chn_by_id() helper function erroneously invokes "of_node_put()" on the "udmax_np" device-node passed to it, without having incremented its reference count at any point. Fix it.

Repetition requires local actions such as driver bind/unbind or module reload, so local access is the applicable vector.\nAC:L - The unbalanced of_node_put() executes unconditionally on every call path, success and failure alike, with no race to win and no memory-layout precondition the attacker cannot influence. Each invocation \u2014 including every deferred-probe retry \u2014 deterministically drops one reference.\nPR:L - No capability check, credential test, or access-control gate exists anywhere between the entry point and the underflow, and the reference is dropped automatically during boot-time probe without any privileged action being needed to create the condition. Choosing the higher-severity reading, a basic local user rather than real root is treated as sufficient.\nUI:N - The refcount underflow happens inside the driver\u0027s own probe/channel-request flow with no victim action required \u2014 no filesystem mount, file open, or device attach by another user is part of the trigger.\nS:U - The corrupted object is a kernel OF device_node, and all consequences \u2014 the erroneous release, the refcount saturation warning, and any subsequent use-after-free \u2014 remain within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The immediate of_node_release() failure path dumps a kernel stack trace exposing addresses and symbols, and on DT-overlay-based K3 platforms the premature refcount-zero permits the node to be freed while still referenced, yielding a use-after-free read primitive over device_node contents. Per use-after-free guidance this is High.\nI:H - A device_node freed while other subsystems retain pointers is a classic heap-spray target whose properties, full_name, and data pointers are written through, converting the underflow into an arbitrary-write and control-flow-hijack primitive. Use-after-free is scored High for integrity.\nA:H - The underflow reaches refcount_warn_saturate() with the \"refcount_t: underflow; use-after-free\" splat, which is a fatal panic under panic_on_warn or CONFIG_BUG_ON_DATA_CORRUPTION, and the resulting use-after-free causes kernel oopses even when not weaponized."

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
