CVE-2023-2598
A flaw was found in the fixed buffer registration code for iouring iosqebufferregister in iouring/rsrc.c in the Linux kernel that allows out-of-bounds access to physical memory beyond the end of the buffer. This flaw enables full local privilege escalation...
CVE-2023-2598
The CVE-2023-2598 issue arises from a flaw in Linux kernel io_uring buffer registration (io_sqe_buffer_register) that can trigger out-of-bounds access to physical memory beyond the end of the buffer, enabling local privilege escalation. Public discussions and PoC-like exploits demonstrate local e...

Ubuntu 22.04 LTS : Linux kernel (OEM) vulnerabilities (USN-6071-1)
The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6071-1 advisory. It was discovered that the Traffic-Control Index TCINDEX implementation in the Linux kernel did not properly perform filter deactivation in some...
There exists a use-after-free vulnerability in the Linux kernel through io_uring and the IORING_OP_SPLICE operation. If IORING_OP_SPLICE is missing the IO_WQ_WORK_FILES flag which signals that the operation won't use current->nsproxy so its reference counter is not increased. This assumption is not always true as calling io_splice on specific files will call the get_uts function which will use current->nsproxy leading to invalidly decreasing its reference counter later causing the use-after-free vulnerability. We recommend upgrading to version 5.10.160 or above
