CVE-2020-29534

Published: 3 December 2020

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

From the Ubuntu Security Team

Jann Horn discovered that the io_uring subsystem in the Linux kernel did not properly perform reference counting in some situations. A local attacker could use this to expose sensitive information or possibly escalate privileges.
