CVE-2022-49997

In the Linux kernel, the following vulnerability has been resolved:

net: lantiq_xrx200: restore buffer if memory allocation failed

In a situation where memory allocation fails, an invalid buffer address is stored. When this descriptor is used again, the system panics in the build_skb() function when accessing memory.

This vulnerability does not affect Red Hat Enterprise Linux as the Lantiq XRX200 network driver is not enabled in supported kernels. The affected code is specific to embedded MIPS architecture platforms that are not supported by Red Hat.
