CVE-2023-54123

The CVE-2023-54123 issue is in the Linux kernel md/raid10 path where, in the error path of raid10_run(), conf is freed but conf->bio_split is not, causing a memory leak. The root cause was that memory allocated for conf->bio_split was not freed in all error-handling paths; three exit points...

CVE-2023-54089

CVE-2023-54089 : In the Linux kernel, the virtio_pmem path did not assign REQ_OP_WRITE for flush bios, causing submit_bio_noacct() to fail when flushing PMEM-backed devices (e.g., during mkfs.xfs). The root cause is that async_pmem_flush() allocated a flush bio without setting REQ_OP_WRITE, so th...
