CVE-2026-63928

The CVE-2026-63928 entry concerns the Linux kernel USB serial omninet driver. The issue is a memory corruption risk when handling a small endpoint: bulk-out buffers must be at least as large as the hardcoded transfer size to prevent user‑controlled slab corruption if a malicious device reports a ...

CVE-2026-63903 USB: serial: belkin_sa: validate interrupt status length

In the Linux kernel, the following vulnerability has been resolved: USB: serial: belkinsa: validate interrupt status length The Belkin interrupt callback treats interrupt data as a four-byte status report and reads LSR/MSR fields at offsets 2 and 3. The interrupt-in buffer length is derived from...

CVE-2026-63902 USB: serial: cypress_m8: validate interrupt packet headers

In the Linux kernel, the following vulnerability has been resolved: USB: serial: cypressm8: validate interrupt packet headers cypressreadintcallback parses the interrupt-in buffer according to the selected Cypress packet format. Format 1 has a two-byte status/count header and format 2 has a...

CVE-2026-63902

The CVE-2026-63902 issue affects the Linux kernel USB-serial Cypress M8 driver. cypress_read_int_callback() parses the interrupt-in buffer for two Cypress packet formats (format 1: two-byte status/count header; format 2: one-byte combined header). The interrupt buffer is sized from the endpoint w...
