CVE-2026-63952

A flaw was found in the Linux kernel's memfd component. When the SEALEXEC flag is used to create a memory file descriptor, the SEALWRITE flag is implicitly applied to prevent writing to executable memory. However, this implicit write protection is applied after checks that should deny writable...

SUSE CVE-2026-63952

In the Linux kernel, the following vulnerability has been resolved: memfd: deny writeable mappings when implying SEALWRITE When SEALEXEC is added, SEALWRITE is implied to make W^X. But the implied seal is set after the check that makes sure the memfd can not have any writable mappings. This means...
