CVE-2025-39827

CVE-2025-39827 concerns the Linux kernel net/rose subsystem: the rose_neigh refcounting used two separate counters (count from rose_node and use from rose_sock). The patch merges these into a single refcount (use) and updates rose_rt_free(), rose_rt_device_down(), and rose_clear_route() to releas...

CVE-2025-39826 net: rose: convert 'use' field to refcount_t

In the Linux kernel, the following vulnerability has been resolved: net: rose: convert 'use' field to refcountt The 'use' field in struct roseneigh is used as a reference counter but lacks atomicity. This can lead to race conditions where a roseneigh structure is freed while still being reference...
