CVE-2026-63901 Details
Description
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.
A memory corruption vulnerability has been identified in the Linux kernel's USB serial Digi Acceleport driver. This issue arises from the absence of proper sanity checks on the bulk-out buffer sizes, allowing for out-of-bounds memory accesses or slab corruption. The vulnerability can be exploited if a malicious device reports smaller buffer sizes than expected. The problem has been addressed by adding the necessary buffer size checks to prevent such memory corruption.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched kernel can be found on the official Linux kernel website.
