CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:HIn 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(). A flaw was found in the efivarfs component of the Linux kernel. This vulnerability, an information disclosure issue, arises from incorrect error handling in the efivar_entry_get function. An unprivileged local attacker can exploit this by reading from efivarfs, potentially causing uninitialized kernel memory to be copied to userspace. This could allow the attacker to obtain sensitive kernel memory contents, which may aid in bypassing security mitigations.
