Details

In the Linux kernel, the following vulnerability has been resolved: cxl/acpi: Fix a use-after-free in cxlparsecfmws() KASAN and KFENCE detected an user-after-free in the CXL driver. This happens in the cxldecoderadd() fail path. KASAN prints the following error: BUG: KASAN: slab-use-after-free in cxlparsecfmws (drivers/cxl/acpi.c:299) This happens in cxlparsecfmws(), where putdevice() is called, releasing cxld, which is accessed later. Use the local variables in the deverr() instead of pointing to the released memory. Since the dev_err() is printing a resource, change the open coded print format to use the %pr format specifier.
