The vulnerability of the mlx5_irq_alloc() function in the drivers/net/ethernet/mellanox/mlx5/core/pci_irq.c file of the Mellanox Ethernet network adapter driver for the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the mlx5irqalloc function in the drivers/net/ethernet/mellanox/mlx5/core/pciirq.c file of the Mellanox Ethernet network adapter driver for the Linux operating system is related to the distribution of resources without any restrictions or regulation. Exploiting this...

CVE-2026-64073

A flaw was found in the Linux kernel, specifically within the irqwork subsystem when running on systems configured with PREEMPTRT. This vulnerability is a use-after-free, where the system attempts to access memory after it has been released. A local attacker could exploit this timing issue to cau...
