CVE-2022-49366

CVE-2022-49366 affects ksmbd in the Linux kernel. The vulnerability arises in smb_check_perm_dacl() when id and uid have the same value, causing a path to exit the loop without decrementing the reference count of the posix_acls object (increased by get_acl()), which may lead to memory leaks. The ...

CVE-2022-49367

Summary (CVE-2022-49367) In the Linux kernel, the mv88e6xxx DSA MDIO registration path contains a refcount leak. The function of_get_child_by_name() returns a node pointer with an incremented refcount, but of_node_put() is not called when finished, leaking references. mv88e6xxx_mdio_register() fo...
