CVE-2022-50025 Details
Description
In the Linux kernel, the following vulnerability has been resolved: cxl: Fix a memory leak in an error handling path A bitmap_zalloc() must be balanced by a corresponding bitmap_free() in the error handling path of afu_allocate_irqs().
A memory leak vulnerability has been identified in the Linux kernel's CXL (Compute Express Link) subsystem. The issue arises in the error handling path of the 'afu_allocate_irqs()' function, where a 'bitmap_zalloc()' operation is not properly balanced by a corresponding 'bitmap_free()'. This oversight can lead to resource leaks.
