- Summary
- efivarfs: fix error propagation in efivar_entry_get()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
efivarfs: fix error propagation in efivar_entry_get()
efivar_entry_get() always returns success even if the underlying __efivar_entry_get() fails, masking errors.
This may result in uninitialized heap memory being copied to userspace in the efivarfs_file_read() path.
Fix it by returning the error from __efivar_entry_get().
