Description

In the Linux kernel before 4.15, fs/ocfs2/aops.c omits use of a semaphore and consequently has a race condition for access to the extent tree during read operations in DIRECT mode, which allows local users to cause a denial of service (BUG) by modifying a certain e_cpos field.

Weakness classification

  • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
