| Description: | Summary:
The remote host is missing an update for the 'linux-oem-6.1' package(s) announced via the USN-6033-1 advisory.
Vulnerability Insight:
It was discovered that the Traffic-Control Index (TCINDEX) implementation
in the Linux kernel did not properly perform filter deactivation in some
situations. A local attacker could possibly use this to gain elevated
privileges. Please note that with the fix for this CVE, kernel support for
the TCINDEX classifier has been removed. (CVE-2023-1829)
William Zhao discovered that the Traffic Control (TC) subsystem in the
Linux kernel did not properly handle network packet retransmission in
certain situations. A local attacker could use this to cause a denial of
service (kernel deadlock). (CVE-2022-4269)
Thadeu Cascardo discovered that the io_uring subsystem contained a double-
free vulnerability in certain memory allocation error conditions. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2023-1032)
It was discovered that the TUN/TAP driver in the Linux kernel did not
properly initialize socket data. A local attacker could use this to cause a
denial of service (system crash). (CVE-2023-1076)
It was discovered that the Real-Time Scheduling Class implementation in the
Linux kernel contained a type confusion vulnerability in some situations. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-1077)
It was discovered that the ASUS HID driver in the Linux kernel did not
properly handle device removal, leading to a use-after-free vulnerability.
A local attacker with physical access could plug in a specially crafted USB
device to cause a denial of service (system crash). (CVE-2023-1079)
It was discovered that the io_uring subsystem in the Linux kernel did not
properly perform file table updates in some situations, leading to a null
pointer dereference vulnerability. A local attacker could use this to cause
a denial of service (system crash). (CVE-2023-1583)
It was discovered that the Xircom PCMCIA network device driver in the Linux
kernel did not properly handle device removal events. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2023-1670)
It was discovered that the APM X-Gene SoC hardware monitoring driver in the
Linux kernel contained a race condition, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or expose sensitive information (kernel memory).
(CVE-2023-1855)
It was discovered that a race condition existed in the Bluetooth HCI SDIO
driver, leading to a use-after-free vulnerability. A local attacker could
use this to cause a denial of service (system crash). (CVE-2023-1989)
It was discovered that the ST NCI NFC driver did not properly handle device
removal events. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2023-1990)
Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2
mitigations with prctl syscall ... [Please see the references for more information on the vulnerabilities]
