The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2478-1 advisory.
The usb_serial_console_disconnect function in drivers/usb/serial/console.c in the Linux kernel before 4.13.8 allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device, related to disconnection and failed setup.
(CVE-2017-16525)
Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage. (CVE-2021-26341)
An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)
A use-after-free flaw was found in the Linux kernel’s Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)
In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds read due to improper input validation. This could lead to local information disclosure if a malicious USB HID device were plugged in, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream kernel (CVE-2022-20132)
In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead to local escalation of privilege when opening and closing inet sockets with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29900)
Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29901)
drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.
(CVE-2022-33981)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
