Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ibprctlset function updates the Thread Information Flags TIFs for the task and updates the SPECCTRL MSR in the function speculationctrlupdate, but the IBPB is only issued at the next schedul...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: hugetlbfs: Do not delete the error page from the page cache. This change is very similar to the change made for shmem 1. It addresses the same issue, but for the HugeTLBFS mechanism instead. Currently, when a poisoned HugeTLB pag...

CVE-2026-89603

CVE-2026-89603 is a race condition in the Linux kernel's syscall_trace_enter() that allows seccomp filter bypass via ptrace. When a thread is stopped for ptrace, another thread can install a seccomp filter with SECCOMP_FILTER_FLAG_TSYNC; however, syscall_trace_enter() evaluates a cached 'work' va...

CVE-2026-89489

CVE-2026-89489 affects the Linux kernel on the openrisc (or1k) architecture. The sys_or1k_atomic() syscall (number 244) swaps two user-supplied words via hand-written assembly without validating the pointers with access_ok() and without exception table entries for the four memory accesses. An unp...
