GHSA-726G-XGHF-35VC
Vulnerability from github – Published: 2025-05-02 18:31 – Updated: 2025-11-10 18:30In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add()
Port is allocated by sas_port_alloc_num() and rphy is allocated by either sas_end_device_alloc() or sas_expander_alloc(), all of which may return NULL. So we need to check the rphy to avoid possible NULL pointer access.
If sas_rphy_add() returned with failure, rphy is set to NULL. We would access the rphy in the following lines which would also result NULL pointer access.
