| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.8
Description
The issue is related to the rose ioctl function in the net/rose/af rose.c module of the Linux kernel, which implements the Amateur Radio X.25 PLP (Rose) protocol. It is caused by a use-after-free error due to a race condition in the rose accept function. This can allow an attacker to impact the confidentiality, integrity, and availability of protected information.
Recommendations
For Linux kernel versions prior to 6.6.8, update to version 6.6.8 or later to resolve the issue.
As a temporary workaround, consider disabling the rose ioctl function until a patch is available.
Restrict access to the net/rose/af rose.c module to minimize the risk of exploitation.
