CVE-2026-92495: CVE-2026-92495: güvenlik açığı
Açıklama (NVD)
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Clear VM_MAYWRITE on DBR/toggle page mmap bnxt_re_mmap() rejects VM_WRITE for the DBR_PAGE and TOGGLE_PAGE mmap flags, but a read-only mapping can still retain VM_MAYWRITE. nd later be upgraded with mprotect(PROT_WRITE). This can bypass the write check that only runs at mmap time. Clear VM_MAYWRITE before vm_insert_page() in the shared DBR/toggle-page branch, matching the existing policy that userspace writes are not expected for these pages.
