Description
This security bulletin contains information about 1 security vulnerability.
1) Memory leak (CVE-ID: CVE-2026-23431)
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a memory leak in aml_spisg_probe() when probing the amlogic-spisg driver. A local user can trigger driver probe failures to cause a denial of service.
The issue occurs in error paths after spi_alloc_target() or spi_alloc_host() allocates the controller and the reference is not released. Exploitation requires the vulnerable driver to be probed.
