CVE-2026-89909

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for LoongArch architecture. During initialization, if a specific setup function fails, critical resources are not properly released. This can lead to a resource leak, potentially allowing a local attacker to cause a denial of...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: All reserved memblocks on Node0 are set at initialization. After the commit 61167ad5fecdea "mm: pass nid to reservebootmemregion", a panic occurs if DEFERREDSTRUCTPAGEINIT is enabled: 0.000000 CPU 0 Unable to handle...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Do not crash in stacktop for tasks without vDSO Not all tasks have a vDSO mapped; for example, kthreads never have one. If such a task ever calls stacktop, it will dereference the NULL vdso pointer and crash. This can...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Make cpumaskofnode robust against NUMANONODE. The arch definition of cpumaskofnode cannot handle NUMANONODE—which is a valid index—so a check must be added for this case...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: A “off-by-one” error occurred in buildprologue. Vincent reported that running BPF programs with tailcalls on LoongArch causes a kernel hard lockup. Debugging these issues revealed that the JIT-compiled code missed...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fixed the jump offset calculation in tailcall. The additional call to bpfintjitcompile skips the JIT context initialization. This effectively skips the offset calculation, resulting in outoffset = -1. Therefore, t...
