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...

DEBIAN-CVE-2016-10318

A missing authorization check in the fscryptprocesspolicy function in fs/crypto/policy.c in the ext4 and f2fs filesystem encryption support in the Linux kernel before 4.7.4 allows a user to assign an encryption policy to a directory owned by a different user, potentially creating a denial of...

Linux kernel denial of service vulnerability (CNVD-2016-09487)

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A security vulnerability exists in the mbcache function during ext2 and ext4 filesystem realities in Linux kernel versions 4.5.7 and earlier, which stems from the program...

Kernel: fs: ext4 race condition

A race condition flaw was found in the Linux kernel's ext4 file system implementation that allowed a local, unprivileged user to crash the system by simultaneously writing to a file and toggling the ODIRECT flag using fcntlFSETFL on that file...

UBUNTU-CVE-2014-8086

Race condition in the ext4filewriteiter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service file unavailability via a combination of a write action and an FSETFL fcntl operation for the ODIRECT flag...

DEBIAN-CVE-2013-2015

The ext4orphandel function in fs/ext4/namei.c in the Linux kernel before 3.7.3 does not properly handle orphan-list entries for non-journal filesystems, which allows physically proximate attackers to cause a denial of service system hang via a crafted filesystem on removable media, as demonstrate...

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

The cleanupjournaltail function in the Journaling Block Device JBD functionality in the Linux kernel 2.6 allows local users to cause a denial of service assertion error and kernel oops via an ext3 or ext4 image with an "invalid log first block value."...
