Loading vulnerability…
CVE-2024-54456 is a potential buffer overflow in the Linux kernel NFS subsystem's nfs_sysfs_link_rpc_client() function. The function uses a fixed 64-byte name buffer while the length of clnt->cl_program->name is unknown; direct strcat() use can therefore exceed the destination buffer. The upstream fix replaces the unsafe string-copying and concatenation operations with bounded strscpy() and strncat() calls.
