Segmentation Fault in Linux Kernel's tcm_loop Functionality
CVE-2025-68229
What is CVE-2025-68229?
A vulnerability has been identified in the Linux Kernel's SCSI target subsystem, specifically within the tcm_loop driver. This issue arises when memory allocation for the 'struct scsi_host' fails during the execution of the 'tcm_loop_driver_probe()' function. If the allocation fails and a subsequent attempt is made to dereference the pointer, it results in a segmentation fault, potentially compromising system stability. Proper checks must be implemented to ensure that 'tl_hba->sh' is validated before dereferencing to prevent this critical failure.
