CVE-2026-63899

In the Linux kernel, the following vulnerability has been resolved: USB: serial: mxuport: fix memory corruption with small endpoint Make sure that the bulk-out endpoint max packet size is at least eight bytes to avoid user-controlled slab corruption should a malicious device report a smaller size...

CVE-2026-63899

CVE-2026-63899 concerns a memory corruption in Linux kernel USB serial mxuport implementation. The vulnerability arises when handling the bulk-out endpoint where the maximum packet size could be smaller than safe, enabling user-controlled slab corruption if a malicious USB device reports a small ...
