CVE-2024-52906

Local denial of service via TCP/IP kernel race

Published Dec 25, 2024 · Updated Dec 26, 2024

Race condition in the TCP/IP kernel extension in IBM AIX 7.2, 7.3, VIOS 3.1, and 4.1 allows local users to cause a denial of service. IBM identifies improper synchronization in the extension but has not disclosed the shared resource or conflicting operations. A non-privileged local account is required, and the reported consequence is limited to loss of availability without data disclosure or modification.
