Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: efivarfs: fixed error propagation in efivarentryget The efivarentryget function always returns success, even if the underlying efivarentryget function fails, thereby masking errors. This may result in uninitialized heap memory...

kernel: Linux kernel: Information disclosure in efivarfs via incorrect error propagation

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 efivarentryget function. An unprivileged local attacker can exploit this by reading from efivarfs, potentially causing uninitialized...

CVE-2026-23156

CVE-2026-23156 affects Linux kernel efivarfs: efivar_entry_get() may return success even if __efivar_entry_get() fails, potentially enabling uninitialized heap data to be copied to userspace via efivarfs_file_read(). The root cause is error propagation being suppressed; the fix is to return the e...
