SUSE CVE-2015-7550

The keyctlreadkey function in security/keys/keyctl.c in the Linux kernel before 4.3.4 does not properly use a semaphore, which allows local users to cause a denial of service NULL pointer dereference and system crash or possibly have unspecified other impact via a crafted application that leverag...

SUSE CVE-2015-7872

The keygcunusedkeys function in security/keys/gc.c in the Linux kernel through 4.2.6 allows local users to cause a denial of service OOPS via crafted keyctl commands...

SUSE CVE-2015-8539

The KEYS subsystem in the Linux kernel before 4.4 allows local users to gain privileges or cause a denial of service BUG via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/userdefined.c...

SUSE CVE-2016-0728

The joinsessionkeyring function in security/keys/processkeys.c in the Linux kernel before 4.4.1 mishandles object references in a certain error case, which allows local users to gain privileges or cause a denial of service integer overflow and use-after-free via crafted keyctl commands...

SUSE CVE-2016-4470

The keyrejectandlink function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service system crash via vectors involving a crafted keyctl request2 command...

SUSE CVE-2017-12192

The keyctlreadkey function in security/keys/keyctl.c in the Key Management subcomponent in the Linux kernel before 4.13.5 does not properly consider that a key may be possessed but negatively instantiated, which allows local users to cause a denial of service OOPS and system crash via a crafted...

SUSE CVE-2017-15274

security/keys/keyctl.c in the Linux kernel before 4.11.5 does not consider the case of a NULL payload in conjunction with a nonzero length value, which allows local users to cause a denial of service NULL pointer dereference and OOPS via a crafted addkey or keyctl system call, a different...

SUSE CVE-2017-18270

In the Linux kernel before 4.13.5, a local user could create keyrings for other users via keyctl commands, setting unwanted defaults or causing a denial of service...

kernel: watch queue race condition can lead to privilege escalation

A race condition was found in the Linux kernel's watch queue due to a missing lock in the piperesizering. The race condition occurs when a thread uses ioctlIOCWATCHQUEUESETSIZE to resize the pipe buffer and free the old pipe buffer, while another thread uses keyctl to trigger a notification in th...

kernel: NULL pointer dereference due to KEYCTL_READ on negative key

A vulnerability was found in the Key Management sub component of the Linux kernel, where when trying to issue a KEYTCLREAD on a negative key would lead to a NULL pointer dereference. A local attacker could use this flaw to crash the kernel...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists if a memory leak in keyctl handling. A local user could use this flaw to deplete kernel memory, eventually leading to a denial of service...

kernel: dereferencing NULL payload with nonzero length

A flaw was found in the implementation of associative arrays where the addkey systemcall and KEYCTLUPDATE operations allowed for a NULL payload with a nonzero length. When accessing the payload within this length parameters value, an unprivileged user could trivially cause a NULL pointer...
