kernel: umask not applied on filesystem without ACL support

A vulnerability was found in NFSv4.2 in the Linux kernel, where a server fails to correctly apply umask when creating a new object on filesystem without ACL support for example, ext4 with the "noacl" mount option. This flaw allows a local attacker with a user privilege to cause a kernel informati...

USN-4249-1 e2fsprogs vulnerability

It was discovered that e2fsprogs incorrectly handled certain ext4 partitions. An attacker could possibly use this issue to execute arbitrary code...

USN-4142-1 e2fsprogs vulnerability

It was discovered that e2fsprogs incorrectly handled certain ext4 partitions. An attacker could possibly use this issue to execute arbitrary code...

kernel: fs/ext4/extents.c leads to information disclosure

A flaw was found in the Linux kernel's implementation of ext4 extent management. The kernel doesn't correctly initialize memory regions in the extent tree block which may be exported to a local user to obtain sensitive information by reading empty/uninitialized data from the filesystem...

CVE-2019-13106

Das U-Boot versions 2016.09 through 2019.07-rc4 can memset too much data while reading a crafted ext4 filesystem, which results in a stack buffer overflow and likely code execution...

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...

kernel: out-of-bounds memcpy in fs/ext4/inline.c:ext4_read_inline_data() with crafted ext4 image

The fs/ext4/inline.c:ext4readinlinedata function in the Linux kernel performs a memcpy with an untrusted length value in certain circumstances involving a crafted filesystem that stores the system.data extended attribute value in a dedicated inode. The unbound copy can cause memory corruption or...

kernel: Heap-based buffer overflow in fs/ext4/xattr.c:ext4_xattr_set_entry() with crafted ext4 image

The Linux kernel is vulnerable to a heap-based buffer overflow in the fs/ext4/xattr.c:ext4xattrsetentry function. An attacker could exploit this by operating on a mounted crafted ext4 image...

kernel: NULL pointer dereference in ext4/xattr.c:ext4_xattr_inode_hash() causes crash with crafted ext4 image

The Linux kernel is vulnerable to a NULL pointer dereference in the ext4/xattr.c:ext4xattrinodehash function. An attacker could trick a legitimate user or a privileged attacker could exploit this to cause a NULL pointer dereference with a crafted ext4 image...

kernel: stack-out-of-bounds write infs/jbd2/transaction.c

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound write in the fs/jbd2/transaction.c code, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image...

USN-3753-1 linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities

It was discovered that the generic SCSI driver in the Linux kernel did not properly enforce permissions on kernel memory access. A local attacker could use this to expose sensitive information or possibly elevate privileges. CVE-2017-13168 Wen Xu discovered that a use-after-free vulnerability...

PT-2018-10156 · Linux +5 · Linux Kernel +5

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A flaw was found in the Linux kernel's ext4 filesystem, allowing a local user to cause an out-of-bound access in the ext4 get group info function. This can lead to a denial of service...

Linux Kernel Denial of Service Vulnerability (CNVD-2017-10818)

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the U.S. The NFSv4 implementation is one of the distributed file system protocols. A security vulnerability exists in the 'fscryptprocesspolicy' function in the fs/crypto/policy.c file of the ex...

UBUNTU-CVE-2015-8952

The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6 mishandles xattr block caching, which allows local users to cause a denial of service soft lockup via filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samb...

UBUNTU-CVE-2015-8839

Multiple race conditions in the ext4 filesystem implementation in the Linux kernel before 4.5 allow local users to cause a denial of service disk corruption by writing to a page that is associated with a different user's file after unsynchronized hole punching and page-fault handling...

e2fsprogs Local Buffer Overflow Vulnerability

e2fsprogs Ext2 Filesystem Utilities is a set of disk utilities for the EXT2 filesystem. A local buffer overflow vulnerability exists in e2fsprogs, which can be exploited by an attacker to execute arbitrary code in an affected application...

kernel: ext4: fix inconsistency in ext4_fill_flex_info()

The ext4fillflexinfo function in fs/ext4/super.c in the Linux kernel before 3.2.2, on the x86 platform and unspecified other platforms, allows user-assisted remote attackers to trigger inconsistent filesystem-groups data and possibly cause a denial of service via a malformed ext4 filesystem...

kernel: jbd2: unmapped buffer with _Unwritten or _Delay flags set can lead to DoS

The journalunmapbuffer function in fs/jbd2/transaction.c in the Linux kernel before 3.3.1 does not properly handle the Delay and Unwritten buffer head states, which allows local users to cause a denial of service system crash by leveraging the presence of an ext4 filesystem that was mounted with ...

kernel: jbd/jbd2: invalid value of first log block leads to oops
