Design/Logic Flaw

The EXT4IOCMOVEEXT aka move extents ioctl implementation in the ext4 filesystem in the Linux kernel before 2.6.32-git6 allows local users to overwrite arbitrary files via a crafted request, related to insufficient checks for file permissions...

Design/Logic Flaw

Unspecified vulnerability in the EXT4IOCMOVEEXT aka move extents ioctl implementation in the ext4 filesystem in the Linux kernel 2.6.32-git6 and earlier allows local users to cause a denial of service filesystem corruption via unknown vectors, a different vulnerability than CVE-2009-4131...

Denial of service

The ext4fillflexinfo function in fs/ext4/super.c in the Linux kernel before 2.6.32-git6 allows user-assisted remote attackers to cause a denial of service divide-by-zero error and panic via a malformed ext4 filesystem containing a super block with a large FLEXBG group size aka sloggroupsperflex...

Null pointer dereference

The ext4decodeerror function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service NULL pointer dereference, and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal...

CVE-2009-4307

The CVE-2009-4307 issue affects the Linux kernel ext4 subsystem: the ext4_fill_flex_info function in fs/ext4/super.c allows a remote attacker to trigger a divide-by-zero and panic when a malformed ext4 super block has a large FLEX_BG group size (s_log_groups_per_flex). Impact is denial of service...
