Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from an incorrect sb-ssequence check in jbd2...

The vulnerability of the tcf_ct_handle_fragments() function in the net/sched/act_ct.c module of the net/sched/networking subsystem of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the tcfcthandlefragments function in the net/sched/actct.c module of the net/sched/networking subsystem of the Linux operating system is related to insufficient checking of exceptional states. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2025-37819

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v2m: Prevent use after free of gicv2mgetfwnode With ACPI in place, gicv2mgetfwnode is registered with the pci subsystem as pcimsigetfwnodecb, which may get invoked at runtime during a PCI host bridge probe. But, the...

CVE-2025-37819

CVE-2025-37819 affects the Linux kernel and relates to a use-after-free in irqchip/gic-v2m: gicv2m_get_fwnode() registered as pci_msi_get_fwnode_cb().
