A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS.

IBM Spectrum Scale V4.2.0.0 through V4.2.3.22 and V5.0.0.0 through V5.0.5 could allow a local attacker to cause a denial of service by sending a large number of RPC requests to the mmfsd daemon which would cause the service to crash. IBM X-Force ID: 181991.

IBM Spectrum Scale V5.0.0.0 through V5.0.4.3 and V4.2.0.0 through V4.2.3.21 could allow a local attacker to cause a denial of service crashing the kernel by sending a subset of ioctls on the device with invalid arguments. IBM X-Force ID: 181992.

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, 11.1, and 11.5 could allow local attacker to cause a denial of service inside the "DB2 Management Service".

IBM AIX 7.1, 7.2, 7.3 and VIOS , 3.1 could allow a non-privileged local user to exploit a vulnerability in X11 to cause a buffer overflow that could result in a denial of service or arbitrary code execution. IBM X-Force ID: 243556.  

IBM AIX 7.1, 7.2, 7.3, and VIOS 3.1 could allow a non-privileged local user to exploit a vulnerability in the AIX NFS kernel extension to cause a denial of service. IBM X-Force ID: 238640.

A security vulnerability in the Spectrum Scale 5.0 and 5.1 allows a non-root user to overflow the mmfsd daemon with requests and preventing the daemon to service other requests. IBM X-Force ID: 191599.

IBM AIX 7.1, 7.2, 7.3, and VIOS 3.1could allow a non-privileged local user to exploit a vulnerability in the AIX SMB client to cause a denial of service. IBM X-Force ID: 238639.

IBM AIX 7.1, 7.2, 7.3, and VIOS 3.1could allow a local user with elevated privileges to exploit a vulnerability in the lpd daemon to cause a denial of service. IBM X-Force ID: 238641.

IBM MQ 9.3 CD and 9.4 LTS/CD could allow a local user to cause a denial of service due to improper memory allocation causing a segmentation fault.

IBM SmartCloud Analytics - Log Analysis 1.3.7.0, 1.3.7.1, 1.3.7.2, 1.3.8.0, 1.3.8.1, and 1.3.8.2 could allow a local user to cause a denial of service due to improper validation of specified type of input.

IBM Security Verify Access Appliance 10.0.0 through 10.0.7 uses uninitialized variables when deploying that could allow a local user to cause a denial of service. IBM X-Force ID: 287318.
