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 Linux kernel that stems from the presence of a refcount leak and a iomem leak vulnerability...

CVE-2024-27054

A vulnerability was found in the dasdgenericsetonline function in the Linux Kernel's s390 dasd.c driver, where improper reference count handling on error paths can lead to the refcount value being decreased twice, resulting in an incorrect underflow. This issue can lead to system instability...

CVE-2024-27054

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: fix double module refcount decrement Once the discipline is associated with the device, deleting the device takes care of decrementing the module's refcount. Doing it manually on this error path causes refcount to...

UBUNTU-CVE-2024-27054

CVE-2024-27054

The CVE-2024-27054 issue resides in the Linux kernel s390/dasd path where the module refcount could be decremented twice due to manual handling of refcounts after device association. The vulnerability results in an artificial decrease of the module’s refcount on each error path, rather than keepi...

kernel: bpf: Make bpf_refcount_acquire fallible for non-owning refs

A memory-safety flaw was found in the Linux kernel extended Berkeley Packet Filter eBPF subsystem in the way reference counts are acquired for objects after a failed tree insertion. When a program attempts to acquire a reference to a node that may already have been released, the reference count...

kernel: Linux kernel: Denial of Service due to memory leak in mlx5e driver

A flaw was found in the Linux kernel. This memory leak vulnerability occurs when a flow rule, forwarding packets from an internal port over a tunnel, is split and extra post-action rules are added. The intport object's reference count is incremented but never decremented, leading to the object no...

kernel: irqchip/ti-sci: Fix refcount leak in ti_sci_intr_irq_domain_probe

In the Linux kernel, the following vulnerability has been resolved: irqchip/ti-sci: Fix refcount leak in tisciintrirqdomainprobe ofirqfindparent returns a node pointer with refcount incremented, We should use ofnodeput on it when not needed anymore. Add missing ofnodeput to avoid refcount leak...

kernel: hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new()

A counting logic flaw exists in the Linux kernel. When cigetdomainbusandslot is called, it returns a pci device with refcount incremented. When finishing it, the caller must decrement the reference count by calling pcidevput, leading to the loss of confidentiality of the system...
