CVE-2024-56546

CVE-2024-56546 affects the Linux kernel in drivers/soc/xilinx, specifically xlnx_add_cb_for_suspend. The issue arises if kmalloc fails to allocate cb_data, because the error path does not free eve_data (missing kfree), potentially causing a memory leak and impacting availability. The patch adds t...
