CVE-2021-47086 (GCVE-0-2021-47086)

Vulnerability from cvelistv5 – Published: 2024-03-04 18:06 – Updated: 2025-05-21 08:31

Title

phonet/pep: refuse to enable an unbound pipe

Summary

In the Linux kernel, the following vulnerability has been resolved: phonet/pep: refuse to enable an unbound pipe This ioctl() implicitly assumed that the socket was already bound to a valid local socket name, i.e. Phonet object. If the socket was not bound, two separate problems would occur: 1) We'd send an pipe enablement request with an invalid source object. 2) Later socket calls could BUG on the socket unexpectedly being connected yet not bound to a valid object.

Severity ?
