What is CVE-2025-21772?

A vulnerability has been identified in the Linux kernel's handling of partition tables. This problem arises during the processing of defective partition tables, where improper handling can lead to access violations. Specifically, issues include failing to correctly validate sector sizes given as absurd values, which could allow for out-of-bounds memory access. Additionally, assumptions about the null termination of partition table entries may lead to incorrect memory operations. Proper safeguards have been implemented to mitigate these risks, ensuring robust partition probing and enhancing overall system security.
