CVE-2026-46115
In the Linux kernel, the following vulnerability has been resolved: block: add pgmap check to biovecphysmergeable biovecphysmergeable is used by the request merge, DMA mapping, and integrity merge paths to decide if two physically contiguous bvec segments can be coalesced into one. It currently h...

CVE-2026-46115
In the Linux kernel block subsystem, CVE-2026-46115 was addressed by adding a check so that zone_device_pages_have_same_pgmap() prevents merging bvec segments that span different dev_pagemaps in biovec_phys_mergeable. Root cause: biovec_phys_mergeable() did not verify that two physically contiguo...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of a devpagemap check in the block layer’s biovecphysmergeable function. This...
