kernel: keys: Fix linking a duplicate key to a keyring's assoc_array

A race condition was found in the Linux kernel's keyring subsystem. When concurrent DNS queries resolve the same hostname, a duplicate index key can be created in the keyring's assocarray. The assocarray implementation has a BUGON check that detects this invalid state, causing a kernel crash. Thi...

kernel: Missing permissions check for request_key() destination allows local attackers to add keys to keyring without Write permission

The KEYS subsystem in the Linux kernel omitted an access-control check when writing a key to the current task's default keyring, allowing a local user to bypass security checks to the keyring. This compromises the validity of the keyring for those who rely on it...

USN-3053-1 linux-lts-vivid vulnerabilities

A missing permission check when settings ACLs was discovered in nfsd. A local user could exploit this flaw to gain access to any file by setting an ACL. CVE-2016-1237 It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was initialized before...

USN-2911-1: Linux kernel vulnerability

It was discovered that the Linux kernel keyring subsystem contained a race between read and revoke operations. A local attacker could use this to cause a denial of service system crash...

kernel: denial of service due to memory leak in add_key()

It was found that the Linux kernel's keyring implementation would leak memory when adding a key to a keyring via the addkey function. A local attacker could use this flaw to exhaust all available memory on the system...

CVE-2015-1333

Memory leak in the keylinkend function in security/keys/keyring.c in the Linux kernel before 4.1.4 allows local users to cause a denial of service memory consumption via many addkey system calls that refer to existing keys...
