Description OSIDB Bzimport 2026-07-19 16:09:58 UTC
In the Linux kernel, the following vulnerability has been resolved:

USB: serial: omninet: fix memory corruption with small endpoint

Make sure that the bulk-out buffers are at least as large as the
hardcoded transfer size to avoid user-controlled slab corruption should
a malicious device report a smaller endpoint max packet size than
expected.
