Refcount Leak in Linux Kernel Affects TI PM33XX SoC

CVE-2023-53744

What is CVE-2023-53744?

A refcount leak issue has been identified in the Linux kernel related to the Texas Instruments PM33XX System-on-Chip (SoC). The vulnerability occurs in the wkup_m3_ipc_get() function, which increments a reference count that is not properly decremented in error handling paths. This oversight can lead to resource management issues, potentially compromising system integrity over time. Properly releasing the reference count in error conditions is crucial for maintaining stable operation and preventing memory-related vulnerabilities.
