CVE-2018-10322

The xfs_dinode_verify function in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_ilock_attr_map_shared invalid pointer dereference) via a crafted xfs image.

These are all security issues fixed in the kernel-devel-5.14.6-1.4 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the kernel-devel-longterm-6.6.17-1.1 package on the GA media of openSUSE Tumbleweed.

Hadar Manor discovered that the DCCP protocol implementation in the Linux kernel improperly handled socket reuse, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-16119)

Wen Xu discovered that the XFS file system in the Linux kernel did not properly validate inode metadata in some situations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10322)

It was discovered that the btrfs file system in the Linux kernel contained a use-after-free vulnerability when merging free space. An attacker could use this to construct a malicious btrfs image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2019-19448)

Jay Shin discovered that the ext4 file system implementation in the Linux kernel did not properly handle directory access with broken indexing, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-14314)

Giuseppe Scrivano discovered that the overlay file system in the Linux kernel did not properly perform permission checks in some situations. A local attacker could possibly use this to bypass intended restrictions and gain read access to restricted files. (CVE-2020-16120)

It was discovered that the NFS client implementation in the Linux kernel did not properly perform bounds checking before copying security labels in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)

It was discovered that the NFC implementation in the Linux kernel did not properly perform permissions checks when opening raw sockets. A local attacker could use this to create or listen to NFC traffic. (CVE-2020-26088)

It was discovered that a race condition existed in the hugetlb sysctl implementation in the Linux kernel. A privileged attacker could use this to cause a denial of service (system crash). (CVE-2020-25285)
