CVSS: 7.2EPSS: 0%CPEs: 4EXPL: 1CVE-2019-15794 – Reference counting error in overlayfs/shiftfs error path when used in conjuction with aufs
https://notcve.org/view.php?id=CVE-2019-15794
Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, both replace vma->vm_file in their mmap handlers. On error the original value is not restored, and the reference is put for the file to which vm_file points. On upstream kernels this is not an issue, as no callers dereference vm_file following after call_mmap() returns an error. However, the aufs patchs change mmap_region() to replace the fput() using a local variable with vma_fput(), which will fput() vm_file, leading to a refcount underflow. Overlayfs en el kernel de Linux y shiftfs, un parche no upstream para el kernel de Linux incluido en las series de kernel Ubuntu versiones 5.0 y 5.3, ambos reemplazan vma->vm_file en sus manejadores de mmap. • https://www.exploit-db.com/exploits/47692 https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/eoan/commit/?id=270d16ae48a4dbf1c7e25e94cc3e38b4bea37635 https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/eoan/commit/?id=ef81780548d20a786cc77ed4203fca146fd81ce3 https://usn.ubuntu.com/usn/usn-4208-1 https://usn.ubuntu.com/usn/usn-4209-1 • CWE-672: Operation on a Resource after Expiration or Release •
