CVE-2026-98155
HIGHDescription
In the Linux kernel, the following vulnerability has been resolved:
accel/qaic: Address potential out-of-bounds read in resp_worker()
Although 'commit 2feec5ae5df7 ("accel/qaic: Handle DBC deactivation if the
owner went away")' fixes the scenario it was intended for by walking the
message and only decoding QAIC_TRANS_DEACTIVATE_FROM_DEV, if present, it
skipped over the bounds checking code that is included in decode_message().
This could lead to issues such as reading past the slab allocation's end,
infinite loops or kernel panics. For those issues to happen, a malformed
wire message is needed to be sent from the device.
Instead of duplicating the bounds checking code already present in
decode_message(), use the function inside resp_worker().
