An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.

An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

A vulnerability of remote credential disclosure was discovered in Advan VD-1 firmware versions up to 230. An attacker can export system configuration which is not encrypted to get the administrator’s account and password in plain text via cgibin/ExportSettings.cgi?Export=1 without any authentication.

A XSS found in Advan VD-1 firmware versions up to 230. VD-1 responses a path error message when a requested resource was not found in page cgibin/ssi.cgi. It leads to a reflected XSS because the error message does not escape properly.

A relative path traversal vulnerability found in Advan VD-1 firmware versions up to 230. It allows attackers to download arbitrary files via url cgibin/ExportSettings.cgi?Download=filepath, without any authentication.

Within multiple XEROX products a vulnerability allows remote command execution on the Linux system, as the "nobody" user through a crafted "HTTP" request (OS Command Injection vulnerability in the HTTP interface). Depending upon configuration authentication may not be necessary.

The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.
