CVE-2021-47483 regmap: Fix possible double-free in regcache_rbtree_exit()

In the Linux kernel, the following vulnerability has been resolved: regmap: Fix possible double-free in regcacherbtreeexit In regcacherbtreeinserttoblock, when 'present' realloc failed, the 'blk' which is supposed to assign to 'rbnode-block' will be freed, so 'rbnode-block' points a freed memory,...

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...

CVE-2021-47441

CVE-2021-47441 concerns the Linux kernel mlxsw thermal driver. The issue arises when cooling state is set above the driver’s maximum state (e.g., cur_state=18 while max_state=10), which triggers out-of-bounds memory accesses in thermal statistics code. The thermal maintainer indicates it is the d...
