CVE-2026-64427

CVE-2026-64427 is a NULL pointer dereference in the Linux kernel's HID Logitech DJ driver (hid_logitech_dj). A specially crafted device descriptor that creates a DJ short output report (report ID 0x20) containing only padding items causes rep->maxfield to remain zero. When the validation error...

CVE-2026-64398

CVE-2026-64398 affects the Linux kernel ksmbd component. A permission check bypass in FSCTL_SET_ZERO_DATA allows an authenticated SMB client with only FILE_WRITE_ATTRIBUTES to zero out file data via fsctl path, bypassing per-handle checks. The operation uses vfs_fallocate(PUNCH_HOLE/ZERO_RANGE) a...
