Linux io_uring Buffer Overflow DoS
The vulnerability of the iouring subsystem in the fs/iouring.c module of the Linux operating system is related to the execution of operations outside the buffer in memory. Exploiting this vulnerability can allow an attacker to disclose sensitive information or cause service failures...
CVE-2023-1032
The Linux kernel iouring IORINGOPSOCKET operation contained a double free in function syssocketfile in file net/socket.c. This issue was introduced in da214a475f8bd1d3e9e7a19ddfeb4d1617551bab and fixed in 649c15c7691e9b13cbe9bf6c65c365350e056067...

OESA-2023-1157 kernel security update
The Linux Kernel, the operating system core itself. Security Fixes: There is a logic error in iouring's implementation which can be used to trigger a use-after-free vulnerability leading to privilege escalation. In the ioprepasyncwork function the assumption that the last iograbidentity call cann...
OESA-2023-1152 kernel security update
The Linux Kernel, the operating system core itself. Security Fixes: Due to a vulnerability in the iouring subsystem, it is possible to leak kernel memory information to the user process. timensinstall calls currentissinglethreaded to determine if the current process is single-threaded, but this...
USN-5914-1: Linux kernel (OEM) vulnerabilities
It was discovered that the Upper Level Protocol ULP subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execut...
CVE-2023-23586
A use-after-free vulnerability was discovered in the Linux kernel's iouring subsystem. It was found that it is possible to insert a time namespace's vvar page to process memory space via a page fault. When this time namespace is destroyed, the vvar page is also freed, but not removed from the...
K53092542: Linux kernel vulnerability CVE-2021-20226
Security Advisory Description A use-after-free flaw was found in the iouring in Linux kernel, where a local attacker with a user privilege could cause a denial of service problem on the system The issue results from the lack of validating the existence of an object prior to performing operations ...
K84602160: Linux kernel vulnerability CVE-2021-3491
Security Advisory Description The iouring subsystem in the Linux kernel allowed the MAXRWCOUNT limit to be bypassed in the PROVIDEBUFFERS operation, which led to negative values being usedin memrw when reading /proc//mem. This could be used to create a heap overflow leading to arbitrary code...
SUSE CVE-2023-23586
Due to a vulnerability in the iouring subsystem, it is possible to leak kernel memory information to the user process. timensinstall calls currentissinglethreaded to determine if the current process is single-threaded, but this call does not consider iouring's ioworker threads, thus it is possibl...
Linux kernel information disclosure vulnerability (CNVD-2023-54416)
Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel has an information disclosure vulnerability, which originates from timensinstall call currentissinglethreaded to determine whether the current process is...

CVE-2023-23586
CVE-2023-23586 affects the Linux kernel io_uring subsystem. A time namespace vvar page can be leaked into a process via a page fault because timens_install’s single-thread check ignores io_uring io_worker threads; when the time namespace is destroyed, the vvar page may remain and a subsequent pag...
