Denial Of Service (DoS)

kernel is vulnerable to denial of servie DoS. The vulnerability exists through NULL pointer dereference in fs/xfs/libxfs/xfsinodebuf.c...

kernel: NULL pointer dereference in lookup_slow function

An issue was discovered in the XFS filesystem in fs/xfs/xfsicache.c in the Linux kernel. There is a NULL pointer dereference leading to a system panic in lookupslow on a NULL inode-iops pointer when doing pathwalks on a corrupted xfs image. This occurs because of a lack of proper validation that...

kernel: NULL pointer dereference in fs/xfs/libxfs/xfs_inode_buf.c

An issue was discovered in the XFS filesystem in fs/xfs/libxfs/xfsinodebuf.c in the Linux kernel. A denial of service due to the NULL pointer dereference can occur for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service DoS attacks. The vulnerability exists in an unknown code block in the library fs/xfs/libxfs/xfsattr.c of the component XFS File System because xfsattrshortformaddname in fs/xfs/libxfs/xfsattr.c mishandles ATTRREPLACE operations with conversion of an...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of serviceDoS attacks. The xfsdinodeverify function in fs/xfs/libxfs/xfsinodebuf.c in the Linux kernel could cause a NULL pointer dereference in xfsilockattrmapshared function. An attacker could exploit this by mounting a crafted xfs filesystem image to cause ...

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - In the Linux kernel, Hisilicon Network Subsystem HNS does not consider the ETHSSPRIVFLAGS case when retrieving ssetcou...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service attacks. A race condition between direct and memory-mapped I/O which is handled with BUGON instead of an I/O failure enables local users to cause a denial of service via system crash. Affected is the functionality of file fs/xfs/xfsaops.c of the...

Denial Of Service (DoS)

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic acce...

Denial Of Service (DoS)

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's XFS file system handled replacing of remote attributes under certain conditions. A local user with access to XFS file system mount could potentially use this fla...
