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...

SUSE CVE-2019-19241

In the Linux kernel before 5.4.2, the iouring feature leads to requests that inadvertently have UID 0 and full capabilities, aka CID-181e448d8709. This is related to fs/io-wq.c, fs/iouring.c, and net/socket.c. For example, an attacker can bypass intended restrictions on adding an IPv4 address to...

SUSE CVE-2020-29534

An issue was discovered in the Linux kernel before 5.9.3. iouring takes a non-refcounted reference to the filesstruct of the process that submitted a request, causing execve to incorrectly optimize unsharefd, aka CID-0f2122045b94...

SUSE CVE-2021-3491

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 execution in the kernel. It was...

SUSE CVE-2021-20226
