Important: kernel-livepatch-4.14.177-139.253

Issue Overview: A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending...

CVE-2020-10732

A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data...

The vulnerability of the ext4_protect_reserved inode function (fs/ext4/block_validity.c) in the Linux kernel allows a attacker to cause a service failure.

The vulnerability of the ext4protectreserved inode function fs/ext4/blockvalidity.c in the Linux kernel involves uncontrolled resource consumption. Exploiting this vulnerability could allow an attacker to cause service failures...

UBUNTU-CVE-2019-14901

A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability ...

CVE-2019-13272

A flaw was found in the way PTRACETRACEME functionality was handled in the Linux kernel. The kernel's implementation of ptrace can inadvertently grant elevated permissions to an attacker who can then abuse the relationship between the tracer and the process being traced. This flaw could allow a...

UBUNTU-CVE-2019-10126

A flaw was found in the Linux kernel. A heap based buffer overflow in mwifiexuapparsetailies function in drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory corruption and possibly other consequences...

CVE-2018-16885

A flaw was found in the Linux kernel that allows the userspace to call memcpyfromiovecend and similar functions with a zero offset and buffer length which causes the read beyond the buffer boundaries, in certain cases causing a memory access fault and a system halt by accessing invalid memory...

kernel: out-of-bound write in ext4_init_block_bitmap function with a crafted ext4 image

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bounds write and a denial of service or unspecified other impact is possible by mounting and operating a crafted ext4 filesystem image...

CVE-2018-10938

A flaw was found in the Linux kernel present since v4.0-rc1 and through v4.13-rc4. A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipsov4optptr function in net/ipv4/cipsoipv4.c leading to a denial-of-service. A certain non-default...

CVE-2018-10879

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in ext4xattrsetentry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image...

CVE-2017-15128

A flaw was found in the hugetlbmcopyatomicpte function in mm/hugetlb.c in the Linux kernel before 4.13.12. A lack of size check could cause a denial of service BUG...

CVE-2017-15127

A flaw was found in the hugetlbmcopyatomicpte function in mm/hugetlb.c in the Linux kernel before 4.13. A superfluous implicit page unlock for VMSHARED hugetlbfs mapping could trigger a local denial of service BUG...

UBUNTU-CVE-2017-14991

The sgioctl function in drivers/scsi/sg.c in the Linux kernel before 4.13.4 allows local users to obtain sensitive information from uninitialized kernel heap-memory locations via an SGGETREQUESTTABLE ioctl call for /dev/sg0...

BSA-2017-353

Security Advisory ID : BSA-2017-353 Component : Linux Kernel Revision : 3.0: Interim The IPv6 DCCP implementation in the Linux kernel mishandles inheritance, which allows local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue t...

DEBIAN-CVE-2017-8797

The NFSv4 server in the Linux kernel before 4.11.3 does not properly validate the layout type when processing the NFSv4 pNFS GETDEVICEINFO or LAYOUTGET operand in a UDP packet from a remote attacker. This type value is uninitialized upon encountering certain error conditions. This value is used a...

Why you can’t update it all at once?

It’s the second part of our talk with Daniil Svetlov at his radio show “Safe Environment” recorded 29.03.2017. In this part we talk about vulnerabilities in Linux and proprietary software, problems of patch an vulnerability management, and mention some related compliance requirements. Video with...
