CVE-2026-89483

A flaw was found in the Linux kernel's Non-Volatile Memory Express NVMe subsystem. Under specific memory pressure conditions, a local user could trigger a scenario where uninitialized kernel memory is used and potentially exposed. This could lead to information disclosure, revealing sensitive dat...

CVE-2026-89481

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express over TCP nvme-tcp component. A malicious NVMe controller can exploit this vulnerability by sending a Ready to Transfer R2T command for a read request. The host system, failing to properly validate the request direction, will...

CVE-2026-89482

A flaw was found in the nvme-tcp module of the Linux kernel. This vulnerability arises from improper handling of C2HData for REQOPWRITEZEROES commands, where the system fails to adequately validate the data length. A remote attacker could exploit this by sending specially crafted C2HData, leading...

CVE-2026-89480

A flaw was found in the NVMe-TCP implementation of the Linux kernel. This vulnerability occurs when the system completes a data read request even if the connected controller transfers fewer bytes than expected. As a result, the user application receives a mix of legitimate and stale data,...
