The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5865-1 advisory.
In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
A-223375145References: Upstream kernel (CVE-2022-20369)
Non-transparent sharing of return predictor targets between contexts in some Intel® Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)
An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)
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)
A vulnerability, which was classified as problematic, has been found in Linux Kernel. This issue affects the function nilfs_attach_log_writer of the file fs/nilfs2/segment.c of the component BPF. The manipulation leads to memory leak. The attack may be initiated remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-211961 was assigned to this vulnerability. (CVE-2022-3646)
A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is the function nilfs_new_inode of the file fs/nilfs2/inode.c of the component BPF. The manipulation leads to use after free. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue.
The identifier of this vulnerability is VDB-211992. (CVE-2022-3649)
An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur. NOTE: the original discoverer disputes that the overflow can actually happen. (CVE-2022-39842)
drivers/video/fbdev/smscufx.c in the Linux kernel through 5.19.12 has a race condition and resultant use- after-free if a physically proximate attacker removes a USB device while calling open(), aka a race condition between ufx_ops_open and ufx_usb_disconnect. (CVE-2022-41849)
roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free in certain situations where a report is received while copying a report->value is in progress. (CVE-2022-41850)
drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user- space client to corrupt the monitor’s internal memory. (CVE-2022-43750)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
