SUSE 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...

SUSE CVE-2015-8961

The ext4journalstop function in fs/ext4/ext4jbd2.c in the Linux kernel before 4.3.3 allows local users to gain privileges or cause a denial of service use-after-free by leveraging improper access to a certain error field...

SUSE CVE-2016-10208

The ext4fillsuper function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly validate meta block groups, which allows physically proximate attackers to cause a denial of service out-of-bounds read and system crash via a crafted ext4 image...

SUSE CVE-2017-7374

Use-after-free vulnerability in fs/crypto/ in the Linux kernel before 4.10.7 allows local users to cause a denial of service NULL pointer dereference or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be...

SUSE CVE-2017-7495

fs/ext4/inode.c in the Linux kernel before 4.6.2, when ext4 data=ordered mode is used, mishandles a needs-flushing-before-commit list, which allows local users to obtain sensitive information from other users' files in opportunistic circumstances by waiting for a hardware reset, creating a new...

SUSE CVE-2018-1093

The ext4validblockbitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows attackers to cause a denial of service out-of-bounds read and system crash via a crafted ext4 image because balloc.c and ialloc.c do not validate bitmap block numbers...

SUSE CVE-2018-1092

The ext4iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a root directory with a zero ilinkscount, which allows attackers to cause a denial of service ext4processfreeddata NULL pointer dereference and OOPS via a crafted ext4 image...

SUSE CVE-2018-1095

The ext4xattrcheckentries function in fs/ext4/xattr.c in the Linux kernel through 4.15.15 does not properly validate xattr sizes, which causes misinterpretation of a size as an error code, and consequently allows attackers to cause a denial of service getacl NULL pointer dereference and system...

SUSE CVE-2018-10840

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...

SUSE CVE-2018-10877

Linux kernel ext4 filesystem is vulnerable to an out-of-bound access in the ext4extdroprefs function when operating on a crafted ext4 filesystem image...

SUSE 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...

SUSE 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...

SUSE CVE-2018-10880

Linux kernel is vulnerable to a stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4updateinlinedata. An attacker could use this to cause a system crash and a denial of service...

SUSE CVE-2018-10883

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bounds write in jbd2journaldirtymetadata, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image...

SUSE CVE-2018-10882

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

SUSE CVE-2018-10881

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in ext4getgroupinfo function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image...

SUSE CVE-2018-11412

In the Linux kernel 4.13 through 4.16.11, ext4readinlinedata in fs/ext4/inline.c 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...

SUSE CVE-2019-5094

An exploitable code execution vulnerability exists in the quota file functionality of E2fsprogs 1.45.3. A specially crafted ext4 partition can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability...

SUSE CVE-2019-5188

A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability...
