USN-5384-1: Linux kernel vulnerabilities

Read Time:40 Second

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)

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 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)

USN-5383-1: Linux kernel vulnerabilities

Read Time:1 Minute, 41 Second

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)

USN-5381-1: Linux kernel (OEM) vulnerabilities

Read Time:2 Minute, 13 Second

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)

It was discovered that the block layer subsystem in the Linux kernel did
not properly initialize memory in some situations. A privileged local
attacker could use this to expose sensitive information (kernel memory).
(CVE-2022-0494)

It was discovered that the DMA subsystem in the Linux kernel did not
properly ensure bounce buffers were completely overwritten by the DMA
device. A local attacker could use this to expose sensitive information
(kernel memory). (CVE-2022-0854)

Jann Horn discovered that the FUSE file system in the Linux kernel
contained 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-2022-1011)

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)

Hu Jiahui discovered that multiple race conditions existed in the Advanced
Linux Sound Architecture (ALSA) framework, leading to use-after-free
vulnerabilities. A local attacker could use these to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2022-1048)

It was discovered that the USB Gadget file system interface in the Linux
kernel contained 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-2022-24958)

It was discovered that the ST21NFCA NFC driver in the Linux kernel did not
properly validate the size of certain data in EVT_TRANSACTION events. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-26490)

It was discovered that the USB SR9700 ethernet device driver for the Linux
kernel did not properly validate the length of requests from the device. A
physically proximate attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-26966)

It was discovered that the Xilinx USB2 device gadget driver in the Linux
kernel did not properly validate endpoint indices from the host. A
physically proximate attacker could possibly use this to cause a denial of
service (system crash). (CVE-2022-27223)

赵子轩 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not
properly perform reference counting in some error conditions. A local
attacker could use this to cause a denial of service. (CVE-2022-28356)

Vicarius releases free Nmap scanning tool

Read Time:35 Second

Nmap is a popular and versatile tool for port scanning, network discovery, and security auditing, but its scan results can be complex to interpret. Vulnerability remediation platform maker Vicarius wants to change that. It began offering Wednesday a free tool—Nmap Scan Analysis—that security professionals, IT administrators and pentesters can use to get a comprehensive visualization of Nmap scan data.

Nmap users can use the tool to import an XML file of their scan results into the company’s TOPIA dashboard, where the data is analyzed and subsequently displayed in a clear and visually coherent way that includes open ports, services, operating systems, and detected CVEs.
