Description OSIDB Bzimport 2026-07-19 16:07:24 UTC
In the Linux kernel, the following vulnerability has been resolved:

USB: serial: digi_acceleport: fix memory corruption with small endpoints

Add the missing bulk-out buffer size sanity checks to avoid
out-of-bounds memory accesses or slab corruption should a malicious
device report smaller buffers than expected.
