CVE-2026-64368

The CVE-2026-64368 issue affects the Linux kernel’s slab allocator: when red zoning is enabled, zeroing was overly broad and could affect krealloc()’s __GFP_ZERO contract. The root cause is an imprecise check for the tracked requested size; fixes switch to slub_debug_orig_size() to determine if t...

CVE-2026-64366

CVE-2026-64366 affects the Linux kernel HID wacom driver. The vulnerability stems from wacom_wac_queue_insert() calling kfifo_skip() in a loop even when the FIFO could be empty. When empty, stale data in the kmalloc buffer can be read by __kfifo_peek_n() and treated as a record length, advancing ...
