Description
A flaw was found in the Linux kernel's ring-buffer component. This vulnerability occurs because a specific function, ring_buffer_subbuf_order_set(), does not properly manage access when updating internal data structures. This lack of exclusive access allows other parts of the system to read data while it is being modified, which can lead to incorrect memory operations and system crashes. A local attacker could exploit this to cause a Denial of Service (DoS).
