Name of the Vulnerable Software and Affected Versions: Linux Kernel versions prior to v6.0.3 Description: A null pointer dereference issue was discovered in the ext4 write info function. The actual impact and attack plausibility have not yet been proven. Recommendations: For Linux Kernel versions...

kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL
A data leak flaw was found in the way XFSIOCALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A bug has been fixed in the Linux kernel's ext4 file system, specifically in the ext4 es cache extent function, which is called by ext4 split extent at. The issue occurs when running...
kernel: sync of excessive duration via an XFS v5 image with crafted metadata
A flaw was discovered in the XFS source in the Linux kernel. This flaw allows an attacker with the ability to mount an XFS filesystem, to trigger a denial of service while attempting to sync a file located on an XFS v5 image with crafted metadata...
The vulnerability of the ext4_xattr_set_entry() function in the Linux operating system allows a hacker to cause a service failure.
The vulnerability of the ext4xattrsetentry function in the Linux operating system is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to cause a service failure during the renaming of a file in a specially created ext4 file system image...
kernel: NULL pointer dereference in ext4/mballoc.c:ext4_process_freed_data() when mounting crafted ext4 image
The Linux kernel is vulnerable to a NULL pointer dereference in the ext4/mballoc.c:ext4processfreeddata function. An attacker could trick a legitimate user or a privileged attacker could exploit this by mounting a crafted ext4 image to cause a kernel panic...
kernel: xfs: _xfs_buf_find oops on blocks beyond the filesystem end
The xfsbuffind function in fs/xfs/xfsbuf.c in the Linux kernel before 3.7.6 does not validate block numbers, which allows local users to cause a denial of service NULL pointer dereference and system crash or possibly have unspecified other impact by leveraging the ability to mount an XFS filesyst...
kernel: ext4: AIO vs fallocate stale data exposure
Race condition in fs/ext4/extents.c in the Linux kernel before 3.4.16 allows local users to obtain sensitive information from a deleted file by reading an extent that was not properly marked as uninitialized...
kernel: xfs heap overflow
Integer overflow in the xfsaclfromdisk function in fs/xfs/xfsacl.c in the Linux kernel before 3.1.9 allows local users to cause a denial of service panic via a filesystem with a malformed ACL, leading to a heap-based buffer overflow...
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."...
kernel: xfs: potential buffer overflow in xfs_readlink()
Buffer overflow in the xfsreadlink function in fs/xfs/xfsvnodeops.c in XFS in the Linux kernel 2.6, when CONFIGXFSDEBUG is disabled, allows local users to cause a denial of service memory corruption and crash and possibly execute arbitrary code via an XFS image containing a symbolic link with a...
kernel: ext4: kernel panic when writing data to the last block of sparse file
Multiple off-by-one errors in the ext4 subsystem in the Linux kernel before 3.0-rc5 allow local users to cause a denial of service BUGON and system crash by accessing a sparse file in extent format with a write operation involving a block number corresponding to the largest possible 32-bit unsign...
security flaw
The ext2 file system code in Linux kernel 2.6.x allows local users to cause a denial of service crash via an ext2 stream with malformed data structures that triggers an error in the ext2checkpage due to a length that is smaller than the minimum...
security flaw
Linux kernel 2.6.x, when using both NFS and EXT3, allows remote attackers to cause a denial of service file system panic via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle inode number, which triggers an error and causes an exported directory to be remounted...
security flaw
xattr.c in the ext2 and ext3 file system code for Linux kernel 2.6 does not properly compare the nameindex fields when sharing xattr blocks, which could prevent default ACLs from being applied...
