Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: s390/syscalls: Added a spectre boundary for the syscall dispatch table. The s390 syscall number is directly controlled by the user space, but there is no arrayindexnospec boundary to prevent access beyond the syscall function...

CVE-2026-31483

CVE-2026-31483 affects the s390 architecture in the Linux kernel. The root cause is a missing array_index_nospec() boundary in the syscall dispatch table, allowing a user-controlled syscall number to exceed the function pointer table and potentially read kernel memory via speculative execution (S...
