Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

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...

LoongArch: Add spectre boundry for syscall dispatch table

...

CVE-2026-45993

A flaw was found in the Linux kernel, specifically affecting the LoongArch architecture. The system call syscall dispatch table, which handles requests from user programs, does not properly validate the syscall number provided by userspace. This missing boundary check could allow a local attacker...
