7.8 HIGH — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Description

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().

Affected configurations

• linux linux kernel (>= 6.0 < 6.1.162) • linux linux kernel (>= 6.2 < 6.6.123) • linux linux kernel (>= 6.7 < 6.12.69) • linux linux kernel (>= 6.13 < 6.18.9) • linux linux kernel 6.19
