SUSE 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...

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-2018-1092

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-2018-1093

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-2018-1095

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...
