Denial Of Service (DoS)

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: A heap-based buffer overflow flaw was found in the Linux kernel's iSCSI target subsystem. A remote attacker could use a specially-crafted iSCSI request to caus...

Denial Of Service (DoS)

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: A memory leak flaw was found in the way the Linux kernel's memory subsystem handled resource clean up in the mmap failure path when the MAPHUGETLB flag was set...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service. A local user is able to crash the process in a divide-by-zero error and kernel oops by reading TCP stats...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service. A local user is able to crash the system via vectors involving munmap and close system call due to multiple race conditions in the function madviseremove in mm/madvise.c...

Netlink Messages Spoofing

kernel-rt is vulnerable to message spoofing. A flaw was found in the way Netlink messages without SCMCREDENTIALS used for authentication data set were handled. When not explicitly set, the data was sent but with all values set to 0, including the process ID and user ID, causing the Netlink messag...

Information Disclosure

kernel-rt is vulnerable to information disclosure. Local users are able to obtain confidential information from the kernel stack memory via recvfrom or recvmsgsystem call on an RDS socket. due to failure to initialize certain structure member in the rdsrecvmsg function in net/rds/recv.c...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service. A heap-based buffer overflow in the function udfloadlogicalvol in fs/udf/super.c allows remote attackers to crash the system using a malicious UDF filesystem...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service A use-after-free flaw was found in the Linux kernel's memory management subsystem in the way quota handling for huge pages was performed. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their...

RHEL 7 : kernel-rt (RHSA-2019:0188)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:0188 advisory. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Securi...

Information Disclosure

kernel-rt is vulnerable to information disclosure attacks. The vulnerability exists through an information disclosure vulnerability in the Upstream kernel encrypted-key...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as net/xfrm/xfrmpolicy.c in the Linux kernel through 4.12.3, when CONFIGXFRMMIGRATE is enabled, does not ensure that the dir value of xfrmuserpolicyid is XFRMPOLICYMAX or less, which allows local users to cause a...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as the XFRM dump policy implementation in net/xfrm/xfrmuser.c in the Linux kernel before 4.13.11 allows local users to gain privileges or cause a denial of service use-after-free via a crafted SORCVBUF setsockopt...

Arbitrary Code Execution

kernel-rt is vulnerable to arbitrary code execution attacks. The vulnerability exists as arch/x86/kvm/mmu.c in the Linux kernel through 4.13.5, when nested virtualisation is used, does not properly traverse guest pagetable entries to resolve a guest virtual address, which allows L1 guest OS users...

ASLR Bypass

kernel-rt is vulnerable to ASLR bypass attacks. The vulnerability exists as the archpickmmaplayout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists in the Linux kernel through 4.14.13, the rdsmessageallocsgs function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write related to the rdsrdmaextrasize...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as 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...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as the pivotroot implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service...
