Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a difference-one error in the buildprologue function of the LoongArch architecture BPF...

CVE-2025-22049

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Increase ARCHDMAMINALIGN up to 16 ARCHDMAMINALIGN is 1 by default, but some LoongArch-specific devices such as APBDMA require 16 bytes alignment. When the data buffer length is too small, the hardware may make an error...

CVE-2025-22049

The CVE-2025-22049 issue affects the Linux kernel's LoongArch code. It fixes the need to raise ARCH_DMA_MINALIGN from 1 to 16 to accommodate LoongArch devices (e.g., APBDMA) that require 16-byte alignment. The vulnerability stemmed from potential DMA cacheline write errors when data buffers were ...

CVE-2025-22048

The CVE-2025-22048 entry concerns LoongArch support in the Linux kernel where BPF return-value handling was fixed. The root cause was that after a commit that sign-extended the a5 return register to a0, the subsequent propagation from a0 back to a5 occurred for all function calls, which was incor...
