There is no fixed version for RHEL:8 kernel-cross-headers.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-cross-headers package and not the kernel-cross-headers package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
tipc: guard against string buffer overrun
Smatch reports that copying media_name and if_name to name_parts may overwrite the destination.
.../bearer.c:166 bearer_name_validate() error: strcpy() 'media_name' too large for 'name_parts->media_name' (32 vs 16) .../bearer.c:167 bearer_name_validate() error: strcpy() 'if_name' too large for 'name_parts->if_name' (1010102 vs 16)
This does seem to be the case so guard against this possibility by using strscpy() and failing if truncation occurs.
Introduced by commit b97bf3fd8f6a ("[TIPC] Initial merge")
Compile tested only.
