CVE-2021-47482

CVE-2021-47482 concerns a Linux kernel issue in the batman-adv code path. The root cause was incorrect error handling in batadv_mesh_init(), which could trigger a free when some batadv_init() failed and risk operating on uninitialized fields. Syzbot observed an ODEBUG warning in batadv_nc_mesh_fr...

CVE-2021-47483

CVE-2021-47483 affects the Linux kernel regmap subsystem (regcache_rbtree). The issue is a double-free in error handling when a reallocation fails, causing rbnode->block to reference freed memory. The fix moves the rbnode->block assignment to immediately after a successful reallocation, ens...
