CVE-2025-38444
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
raid10: cleanup memleak at raid10_make_request
If raid10_read_request or raid10_write_request registers a new request and the REQ_NOWAIT flag is set, the code does not free the malloc from the mempool.
V4: changing backing tree to see if CKI tests will pass. The patch code has not changed between any versions.
