kernel: nvmet-tcp: fix race between ICReq handling and queue teardown

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. A race condition exists between the handling of an Initialization Connection Request ICReq and the teardown of a queue. A remote attacker, by sending an ICReq and immediately closing the connection, could trigger a...

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: fix race between ICReq handling and queue teardown nvmettcphandleicreq updates queue-state after sending an Initialization Connection Response ICResp, but it does so without serializing against target-side queue...

CVE-2026-4652

Summary of CVE-2026-4652 (NVMe/TCP) : A remote attacker with network access to an NVMe/TCP target can trigger a kernel panic by sending a CONNECT command for an I/O queue with a bogus or stale CNTLID, leading to an unauthenticated Denial of Service. Affected systems expose an NVMe/TCP target; imp...

CVE-2023-53817

In the Linux kernel, the following vulnerability has been resolved: crypto: lib/mpi - avoid null pointer deref in mpicmpui During NVMeTCP Authentication a controller can trigger a kernel oops by specifying the 8192 bit Diffie Hellman group and passing a correctly sized, but zeroed Diffie Hellamn...

CVE-2025-38397

In the Linux kernel, the following vulnerability has been resolved: nvme-multipath: fix suspicious RCU usage warning When I run the NVME over TCP test in virtme-ng, I get the following "suspicious RCU usage" warning in nvmempathaddsysfslink: ''' 5.024557 T44 nvmet: Created nvm controller 1 for...

kernel: nvme-tcp: fix UAF when detecting digest errors

A use-after-free vulnerability was found in the Linux kernel in drivers/nvme/host/tcp.c in nvmetcpiowork. This issue can occur when a local user continues to read data after the connection finishes. This flaw allows a malicious user to cause a use-after-free problem...

kernel: NULL pointer dereference in nvmet_tcp_execute_request

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service...

AZL-67581 CVE-2024-27435 affecting package kernel 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved: nvme: fix reconnection fail due to reserved tag allocation We found a issue on production environment while using NVMe over RDMA, adminq reconnect failed forever while remote target and network is ok. After dig into it, we found ...

kernel: NULL pointer dereference in nvmet_tcp_execute_request

A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service...

kernel: nvme-tcp: don't access released socket during error recovery

A race condition leading to NULL pointer dereference was found in the Linux kernel NVMe-over-TCP driver's error recovery handling. A local user with privileges to execute NVMe management commands can run the 'nvme list' command while NVMe-over-TCP error recovery work is temporarily failing...
