CVE-2024-54456
In the Linux kernel, the following vulnerability has been resolved: NFS: Fix potential buffer overflowin nfs_sysfs_link_rpc_client() name is char[64] where the size of clnt->cl_program->name remains unknown.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.22%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: NFS: Fix potential buffer overflowin nfs_sysfs_link_rpc_client() name is char[64] where the size of clnt->cl_program->name remains unknown. Invoking strcat() directly will also lead to potential buffer overflow. Change them to strscpy() and strncat() to fix potential issues.
