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. Linux kernel suffers from a memory leak vulnerability that originates from nftsetcatchallflush in net/netfilter/nftablesapi.c not freeing or failing to free dynamically allocat...

The vulnerability of the netfilter kernel module in Linux operating systems, located in the function nf_tables_newrule(), allows an attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the netfilter kernel module in Linux operating systems relates to improper handling when rules are added to the function nftablesnewrule in the net/netfilter/nftablesapi.c module. Exploiting this vulnerability can allow an attacker to compromise the confidentiality, integrity...

The vulnerability of the nf_tables_delrule() function in the /net/netfilter/nf_tables_api.c file of the Linux kernel’s netfilter network interface layer allows a hacker to trigger a service failure.

The vulnerability of the nftablesdelrule function in the /net/netfilter/nftablesapi.c file of the Linux kernel’s netfilter network interface layer is related to improper handling of usage counters, which can lead to a memory leak. Exploiting this vulnerability could allow an attacker to cause a...

OESA-2023-1467 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for...

Denial Of Service (DoS)

qemu is vulnerable to Denial of Service DoS attacks. The flaw allows a crafted guest driver to allocate and initialize a huge number of page tables to be used as a ring of descriptors for CQ and async events, potentially leading to an out-of-bounds read and an application crash...

UBUNTU-CVE-2023-3777

A use-after-free vulnerability in the Linux kernel's netfilter: nftables component can be exploited to achieve local privilege escalation. When nftablesdelrule is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain...
