Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/secretmem: fixed a use-after-free race condition in the fault handler. When a page fault occurs in a secret memory file created with memfdsecret2, the kernel will allocate a new folio for it, mark the underlying page as not...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: secretmem: Disable memfdsecret if arch cannot set the direct map. The memfdsecret syscall returns -ENOSYS if !cansetdirectmap is true. This occurs, for example, in some arm64 configurations, where marking 4k PTEs in the direct ma...

CVE-2025-40272

A use-after-free race condition was found in the secretmem subsystem of the Linux kernel. When two tasks concurrently fault on the same page in a memfdsecret file, the losing task may free its folio before restoring the direct map entry. This allows the freed page to be reallocated while still...
