CVE-2021-43389

Published: 4 November 2021

An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c.

From the Ubuntu Security Team

It was discovered that the ISDN CAPI implementation in the Linux kernel contained a race condition in certain situations that could trigger an array out-of-bounds bug. A privileged local attacker could possibly use this to cause a denial of service or execute arbitrary code.

Notes

AuthorNote
cascardo
Adding a CAPI controller with CMTP requires CAP_NET_ADMIN
in the initial namespace (init_ns). Other ISDN controllers that
use CAPI have been removed upstream.
