Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: The ioaw hook was defined as mmiowb. The commit fb24ea52f78e0d595852e states that “drivers: Explicit invocations of mmiowb were removed.” All occurrences of mmiowb in drivers were removed. However, it is noted that:...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: The hugepteoffset function currently returns a pointer to a PMD slot, even when the underlying entry points to an invalid invalidptetable indicating no mapping. Functions like smapshugetlbrange retrieve this invalid...

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...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: LoongArch: BPF: Prevent out-of-bounds memory access The testtag test triggers an unhandled page fault: ./testtag 130.640218 CPU 0 Unable to handle kernel paging request at virtual address ffff80001b898004, era ==...

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...

CVE-2026-72295

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for LoongArch architecture. An unvalidated interrupt controller irqchip index in the irqfd routing mechanism could allow a local attacker to perform an out-of-bounds memory access. This could lead to a denial of service or...

CVE-2026-72294

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component, specifically within the LoongArch architecture. The kvmvcpuioctlinterrupt function, which can be invoked from userspace, lacks proper validation of interrupt requests. This missing validity check could allow a loca...
