CVE-2026-23156 (opens in a new tab)Amendment
The AlmaLinux security team deemed this advisory irrelevant for AlmaLinux:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rtla package and not the rtla package as distributed by AlmaLinux.
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().
