Description

A flaw was found in the Linux kernel's bcache component. This use-after-free vulnerability occurs when a cached device is stopped while an I/O operation, specifically writing to the superblock, is still in progress. This timing issue can lead to the system attempting to access memory that has already been freed, resulting in a system crash and a Denial of Service (DoS).
