- Summary
- s390/dasd: protect device queue against concurrent access
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: protect device queue against concurrent access
In dasdprofilestart() the amount of requests on the device queue are counted. The access to the device queue is unprotected against concurrent access. With a lot of parallel I/O, especially with alias devices enabled, the device queue can change while dasdprofilestart() is accessing the queue. In the worst case this leads to a kernel panic due to incorrect pointer accesses.
Fix this by taking the device lock before accessing the queue and counting the requests. Additionally the check for a valid profile data pointer can be done earlier to avoid unnecessary locking in a hot path.
