NVD Description

Note: Versions mentioned in the description apply only to the upstream perf-debuginfo package and not the perf-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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().
