Linux io_uring Heap Buffer Overflow Privilege Escalation

The vulnerability of the ioinstallfixedfile function in the iouring subsystem of Linux kernels relates to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to increase their privileges or cause service interruptions...

CVE-2023-2236

A use-after-free vulnerability in the Linux Kernel iouring subsystem can be exploited to achieve local privilege escalation. Both ioinstallfixedfile and its callers call fput in a file in case of an error, causing a reference underflow which leads to a use-after-free vulnerability. We recommend...

CVE-2023-2236: Use After Free

A use-after-free vulnerability in the Linux Kernel iouring subsystem can be exploited to achieve local privilege escalation. Both ioinstallfixedfile and its callers call fput in a file in case of an error, causing a reference underflow which leads to a use-after-free vulnerability. We recommend...

Linux kernel io_uring Heap Buffer Overflow DoS

The vulnerability of the ioinstallfixedfile function in the iouring/filetable.c module of the iouring subsystem in the Linux kernel is related to the use of previously freed memory. Exploiting this vulnerability could allow an attacker to cause a service failure...

A use-after-free flaw was found in io_uring/filetable.c in io_install_fixed_file in the io_uring subcomponent in the Linux Kernel during call cleanup. This flaw may lead to a denial of service.

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. The Linux Kernel suffers from a resource management error vulnerability that stems from a denial of service that could result from a post-release reuse of the iofilatable .c fi...

CVE-2023-0469

A use-after-free flaw was found in iouring/filetable.c in ioinstallfixedfile in the iouring subcomponent in the Linux Kernel during call cleanup. This flaw may lead to a denial of service...

CVE-2023-0469: Integer Underflow (Wrap or Wraparound)

A use-after-free flaw was found in iouring/filetable.c in ioinstallfixedfile in the iouring subcomponent in the Linux Kernel during call cleanup. This flaw may lead to a denial of service...
