Answer in brief
CVE-2026-63860 records a Unknown severity vulnerability in RDMA/core: Prefer NLA_NUL_STRING. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Prefer NLA_NUL_STRING These attributes are evaluated as c-string (passed to strcmp), but NLA_STRING doesn't check for the presence of a \0 terminator. Either this needs to switch to nla_strcmp() and needs to adjust printf fmt specifier to not use plain %s, or this needs to use NLA_NUL_STRING. As the code has been this way for long time, it seems to me that userspace does include the terminating nul, even tough its not enforced so far, and thus NLA_NUL_STRING use is the simpler solution.
