The remote host is missing an update for the 'linux, linux-aws, linux-aws-5.13, linux-azure, linux-azure-5.13, linux-gcp, linux-gcp-5.13, linux-hwe-5.13, linux-intel-5.13, linux-kvm, linux-oracle, linux-oracle-5.13, linux-raspi' package(s) announced via the USN-5383-1 advisory.
Vulnerability Insight:
David Bouman discovered that the netfilter subsystem in the Linux kernel
did not properly validate passed user register indices. A local attacker
could use this to cause a denial of service or possibly execute arbitrary
code. (CVE-2022-1015)
Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver
in the Linux kernel did not properly handle some error conditions. A
physically proximate attacker could use this to cause a denial of service
(system crash). (CVE-2021-43976)
Wenqing Liu discovered that the f2fs file system implementation in the
Linux kernel did not properly validate inode types while performing garbage
collection. An attacker could use this to construct a malicious f2fs image
that, when mounted and operated on, could cause a denial of service (system
crash). (CVE-2021-44879)
It was discovered that the UDF file system implementation in the Linux
kernel could attempt to dereference a null pointer in some situations. An
attacker could use this to construct a malicious UDF image that, when
mounted and operated on, could cause a denial of service (system crash).
(CVE-2022-0617)
David Bouman discovered that the netfilter subsystem in the Linux kernel
did not initialize memory in some situations. A local attacker could use
this to expose sensitive information (kernel memory). (CVE-2022-1016)
Lyu Tao discovered that the NFS implementation in the Linux kernel did not
properly handle requests to open a directory on a regular file. A local
attacker could use this to expose sensitive information (kernel memory).
(CVE-2022-24448)
It was discovered that the VirtIO Bluetooth driver in the Linux kernel did
not properly deallocate memory in some error conditions. A local attacker
could possibly use this to cause a denial of service (memory exhaustion).
(CVE-2022-26878)
It was discovered that the YAM AX.25 device driver in the Linux kernel did
not properly deallocate memory in some error conditions. A local privileged
attacker could use this to cause a denial of service (kernel memory
exhaustion). (CVE-2022-24959)
Affected Software/OS:
'linux, linux-aws, linux-aws-5.13, linux-azure, linux-azure-5.13, linux-gcp, linux-gcp-5.13, linux-hwe-5.13, linux-intel-5.13, linux-kvm, linux-oracle, linux-oracle-5.13, linux-raspi' package(s) on Ubuntu 20.04, Ubuntu 21.10.
