CVE-2024-42320 Information

Description

In the Linux kernel the following vulnerability has been resolved:

s390/dasd: fix error checks in dasd_copy_pair_store()

dasd_add_busid() can return an error via ERR_PTR() if an allocation fails. However two callsites in dasd_copy_pair_store() do not check the result potentially resulting in a NULL pointer dereference. Fix this by checking the result with IS_ERR() and returning the error up the stack.
