- Summary
- cxl/acpi: Fix a use-after-free in cxl_parse_cfmws()
- 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 put_device() is called, releasing cxld, which is accessed later.
Use the local variables in the deverr() instead of pointing to the released memory. Since the deverr() is printing a resource, change the open coded print format to use the %pr format specifier.
