CVE-2026-74634

This vulnerability affects the Linux kernel ring-buffer subsystem. The root cause is that ring_buffer_subbuf_order_set() frees buffer pages even when resizing is disabled, leaving a non-consuming reader exposed to a use-after-free in rb_advance_iter(). The fix returns -EBUSY on resize_disabled, m...
