CVE-2026-74679

CVE-2026-74679 affects the Linux kernel USB gadget NCM function (f_ncm). The variable ndp_index is declared as a signed integer but stores the unsigned return value of get_ncm(). A malicious host can supply a large offset that overflows the signed ndp_index, making it negative. Because the value ...

CVE-2026-74677

CVE-2026-74677 is a use-after-free in the Linux kernel's ipheth USB network driver. The root cause is that ipheth_sndbulk_callback() re-arms the carrier_work delayed work on any non-zero URB status without checking whether the interface is still up. After ipheth_close() drains the work, a late UR...
