Linux kernel 资源管理错误漏洞

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 resource management error vulnerability that originates from a confusion in the instruction responsible for freeing memory in iouring. An attacker...

CVE-2022-3176: Use After Free

There exists a use-after-free in iouring in the Linux kernel. Signalfdpoll and binderpoll use a waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before the queue is freed. Unfortunately, the iouring poll doesn't handle POLLFREE. This allows a...

Amazon Linux 2022 : kernel-livepatch-5.15.29-16.111 (ALAS2022-2022-101)

It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-101 advisory. A use-after-free flaw was found in the Linux kernel's iouring interface subsystem in the way a user triggers a race condition between timeout flush and removal. This flaw allows a local user to crash or...

ASB-A-231494876

In fs, there is a possible use-after-free due to a race condition in iouring timeouts. This could lead to local escalation of privileges with no additional execution privileges needed. User interaction is not needed for exploitation...
