CVE-2026-89771

A flaw was found in the Linux kernel. A race condition exists in the ring buffer resizing mechanism, where tracebuffer subbufsize can be read without proper locking while it is being simultaneously resized. This could allow a local attacker to trigger unpredictable behavior or a denial of service...

CVE-2026-89771

This Linux kernel race condition affects the trace ring buffer resize mechanism. The field trace_buffer::subbuf_size is read locklessly in ring_buffer_read_page() and ring_buffer_read_start() while it can be concurrently modified by ring_buffer_subbuf_order_set(). According to Red Hat, this can a...
