A flaw was found in xorg-x11-server in versions before 21.1.2 and before 1.20.14. An out-of-bounds access can occur in the SProcXFixesCreatePointerBarrier function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...
SUSE CVE-2021-29650
An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to cause a denial of service panic because net/netfilter/xtables.c and include/linux/netfilter/xtables.h lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf...
SUSE CVE-2021-42072
An issue was discovered in Barrier before 2.4.0. The barriers component aka the server-side implementation of Barrier does not sufficiently verify the identify of connecting clients. Clients can thus exploit weaknesses in the provided protocol to cause denial-of-service or stage further attacks...
SUSE CVE-2021-42073
An issue was discovered in Barrier before 2.4.0. An attacker can enter an active session state with the barriers component aka the server-side implementation of Barrier simply by supplying a client label that identifies a valid client configuration. This label is "Unnamed" by default but could...

Linux kernel 安全漏洞
The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. The Linux kernel suffers from a security vulnerability that stems from nVMX allowing speculative execution attacks where L2 can execute a Spectre v2 attack against L1 because L1 believes it does not...
The vulnerability of the KVM virtualization subsystem in the Linux operating system allows a hacker to gain unauthorized access and increase their privileges.
The vulnerability of the KVM virtualization subsystem in the Linux operating system is related to the execution of the Indirect Branch Prediction Barrier IBPB mechanism on the virtual machine when the guest system uses the Indirect Branch Restricted Speculation IBRS mechanism for indirect branch...
The vulnerability of the Indirect Branch Prediction Barrier (IBPB) implementation in AMD microprogramming software allows a hacker to gain unauthorized access to protected information.
The vulnerability of the Indirect Branch Prediction Barrier IBPB implementation in AMD microprocessors is related to improper cleaning of the RAS stack. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information through a secondary channel...
