CVE-2022-49281

CVE-2022-49281 affects Linux kernel CIFS multiuser handling: each user has a separate tcon and handle for a cached directory, but on unmount the kernel must release the pinned dentry for every tcon rather than only the master tcon. If not, unmount can emit warnings of in-use dentries. The issue i...

CVE-2022-49211

CVE-2022-49211 concerns a Linux kernel issue in the MIPS CDMM code path where of_find_compatible_node() returns a node pointer with an incremented refcount and the code omits of_node_put() to release it. The fixed description states: add the missing of_node_put() to release the refcount. Affected...
