CVE-2026-43465

A flaw was found in the Linux kernel's mlx5e driver. This vulnerability arises from incorrect fragment counting when XDP eXpress Data Path multi-buffer programs modify the XDP buffer layout. This issue could allow a local attacker or a specially crafted network packet to trigger a negative...

CVE-2026-43466

A flaw was found in the Linux kernel's mlx5e network driver. During a transmit TX error recovery process, a desynchronization occurs in the Direct Memory Access DMA First-In, First-Out FIFO buffer. This desynchronization causes the system to incorrectly unmap memory addresses, which can lead to...

CVE-2026-43464

A flaw was found in the Linux kernel's mlx5e driver. When using eXpress Data Path XDP multi-buffer programs, an attacker could manipulate the XDP buffer layout. This manipulation leads to incorrect tracking of page fragments, causing a critical error in memory management. The issue can result in ...
