MariaDB ColumnStore 23.02.24 is a Stable (GA) release of MariaDB ColumnStore.

Fixed security vulnerabilities

The bundled Apache Thrift library was updated from 0.23.0 to 0.24.0, which resolves the following vulnerabilities in the C++ bindings that ColumnStore uses:

• CVE-2026-48145

• CVE-2026-48586

• CVE-2026-55969

• CVE-2026-55970

• CVE-2026-58662

Notable changes

• [MCOL-6434] - The Block Resolution Manager now stores its shared memory on a versioned, copy-on-write scheme, so a fatal signal can no longer leave the extent map in a partially written state

• [MCOL-6513] - Updated the bundled Apache Thrift to 0.24.0

Issues fixed

Can result in hang or crash

• [MCOL-6512] - Fixed a potential SIGSEGV in MCSSETPARMS/CALSETPARMS processing

• [MCOL-6528] - PrimProc could reach an inconsistent aggregation state, leading to excessive memory use and a crash

Can result in data corruption

• [MCOL-6434] - Corruption of BRM data after a fatal unrecoverable signal
