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 the fact that the PMD-sized page cache of the mm/shmem module may not be supported by xarray and needs to be...

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, which stems from the xarray of the mm/filemap module being unable to accept arbitrary page cache sizes. On ARM64 systems, a...

CVE-2024-41031

A vulnerability was found in the Linux kernel related to how large page caching is handled, particularly for AMD64 architectures. The issue stems from the xarray data structure's inability to support PMD-sized page caches when the base page size is larger than MAXPAGECACHEORDER. The particular...
