CVE-2022-2602
CVE-2022-2602 is a Linux kernel vulnerability in io_uring related to a use-after-free in the Unix garbage collection path. Multiple connected sources confirm a local, kernel-side issue (io_uring UAF) that can be exploited to crash the kernel and, in PoC scenarios, enable privilege escalation by r...
Linux 6.4 io_uring Use-After-Free Exploit
Linux =6.4: iouring: page UAF via buffer ring mmap Since commit c56e022c0a27 "iouring: add support for user mapped provided buffer ring", landed in Linux 6.4, iouring makes it possible to allocate, mmap, and deallocate "buffer rings". A "buffer ring" can be allocated with iouringregister...,...
Linux io_uring __io_uaddr_map() Dangerous Multi-Page Handling Exploit
iouring: iouaddrmap handles multi-page region dangerously iouaddrmap wants to import a region from userspace, and then address the imported region through the linear mapping area. This requires that the imported region is physically contiguous. A comment in iouaddrmap explains that the imported...
