Buffer overflow

kernel could return a received message length higher than expected, which leads to buffer overflow in a subsequent operation and stops normal operation in Snapdragon Auto, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Wearables, in MDM9150, MDM9206, MDM9607,...

kernel: use-after-free in jbd2_journal_commit_transaction funtion

A flaw was found in the Linux kernel's ext4 filesystem code. A use-after-free is possible in ext4extremovespace function when mounting and operating a crafted ext4 image...

DEBIAN-CVE-2018-20784

In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfsrq's, which allows attackers to cause a denial of service infinite loop in updateblockedaverages or possibly have unspecified other impact by inducing a high load...

kernel: userfaultfd bypasses tmpfs file permissions

A flaw was found in the Linux kernel with files on tmpfs and hugetlbfs. An attacker is able to bypass file permissions on filesystems mounted with tmpfs/hugetlbs to modify a file and possibly disrupt normal system behavior. At this time there is an understanding there is no crash or privilege...

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: drivers/block/loop.c mishandles lo_release serialization allowing denial-of-service

A flaw was found in the Linux kernel's handling of loopback devices. An attacker, who has permissions to setup loopback disks, may create a denial of service or other unspecified actions...

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...

UBUNTU-CVE-2018-18281

Since Linux kernel version 3.2, the mremap syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate removes entries from the pagetables of a task that is in the middle of mremap, a stale TLB entry can remain for a short time that permits access to a physical pag...

kernel: IP fragments with random offsets allow a remote denial of service (FragmentSmack)

A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU...

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...

UBUNTU-CVE-2018-14614

An issue was discovered in the Linux kernel through 4.17.10. There is an out-of-bounds access in removedirtysegment in fs/f2fs/segment.c when mounting an f2fs image...

CVE-2018-10876

A flaw was found in Linux kernel in the ext4 filesystem code. A use-after-free is possible in ext4extremovespace function when mounting and operating a crafted ext4 image...

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...

kernel: Out-of-bounds access via an XFRM_MSG_MIGRATE xfrm Netlink message

The xfrmmigrate function in the net/xfrm/xfrmpolicy.c file in the Linux kernel built with CONFIGXFRMMIGRATE does not verify if the dir parameter is less than XFRMPOLICYMAX. This allows a local attacker to cause a denial of service out-of-bounds access or possibly have unspecified other impact by...

Kernel: error in exception handling leads to DoS

A flaw was found in the way the Linux kernel handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the...

kernel: guest kernel crash during core dump on POWER9 host

A flaw was found in the Linux kernel where a crash can be triggered from unprivileged userspace during core dump on a POWER system with a certain configuration. This is due to a missing processor feature check and an erroneous use of transactional memory TM instructions in the core dump path...
