Threats tagged 'ghsa-rj67-jfhc-gr45'

A vulnerability in the Linux kernel's nvdimm pmem subsystem allowed data writes to proceed after a failed REQ_PREFLUSH flush due to improper error handling in pmem_submit_bio(). This could cause the bio operation to complete successfully despite a failed ordering barrier, potentially leading to data integrity issues. The flaw has been resolved by ensuring the REQ_PREFLUSH flush is run synchronously before copying bio data and completing the bio with the flush error if it fails.
