Descriptions
In the Linux kernel, the following vulnerability has been resolved: net: nfc: fix races in nfc_llcp_sock_get() and nfc_llcp_sock_get_sn() Sili Luo reported a race in nfc_llcp_sock_get(), leading to UAF. Getting a reference on the socket found in a lookup while
holding a lock should happen before releasing the lock. nfc_llcp_sock_get_sn() has a similar problem. Finally nfc_llcp_recv_snl() needs to make sure the socket
found by nfc_llcp_sock_from_sn() does not disappear.

Lyu Tao discovered that the NFS implementation in the Linux kernel did not properly handle requests to open a directory on a regular file. A local attacker could use this to expose sensitive information. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
