    table is deleted (bsc#1202095).
  * CVE-2023-6121: Fixed an out-of-bounds read vulnerability in the NVMe-oF/TCP
    subsystem that could lead to information leak (bsc#1217250).
  * CVE-2023-6606: Fixed an out of bounds read in the SMB client when receiving
    a malformed length from a server (bsc#1217947).
  * CVE-2023-6610: Fixed an out of bounds read in the SMB client when printing
    debug information (bsc#1217946).
  * CVE-2023-6931: Fixed an out of bounds write in the Performance Events
    subsystem when adding a new event (bsc#1218258).
