FKIE_CVE-2026-53148
Vulnerability from fkie_nvd - Published: 2026-06-25 09:16 - Updated: 2026-06-30 14:44
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Clamp XDomain response data copy to allocation size
tb_xdp_properties_request() derives the per-packet copy length from
the response header without checking that it fits in the previously
allocated data buffer. A malicious peer can set its length field
larger than the declared data_length, causing memcpy to write past
the kcalloc allocation.
Clamp the per-packet copy length so that the cumulative offset
never exceeds data_len.
