- Summary
- CVE-2025-21927 affecting package kernel 5.15.200.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
nvme-tcp: fix potential memory corruption in nvmetcprecv_pdu()
nvmetcprecvpdu() doesn't check the validity of the header length. When header digests are enabled, a target might send a packet with an invalid header length (e.g. 255), causing nvmetcpverifyhdgst() to access memory outside the allocated area and cause memory corruptions by overwriting it with the calculated digest.
Fix this by rejecting packets with an unexpected header length.
