Lack of websocket authentication in Lens causes remote code execution when visiting a malicious website

Linux users running Lens 5.2.6 and earlier could be compromised by visiting a malicious website. The malicious website could make websocket connections from the victim's browser to Lens and so operate the local terminal feature. This would allow the attacker to execute arbitrary commands as the Lens user.

kernel: mwifiex_usb_recv() in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker to cause DoS via crafted USB device

In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).

kernel: an array-index-out-bounds in detach_capi_ctr in drivers/isdn/capi/kcapi.c

An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c.

kernel: Insufficient validation of user-supplied sizes for the MSG_CRYPTO message type

An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type.

kernel: use-after-free in the SELinux handler for PTRACE_TRACEME

An issue was discovered in the Linux kernel before 5.14.8. A use-after-free in selinux_ptrace_traceme (aka the SELinux handler for PTRACE_TRACEME) could be used by local attackers to cause memory corruption and escalate privileges, aka CID-a3727a8bac0a. This occurs because of an attempt to access the subjective credentials of another task.

kernel: ppc: kvm: allows a malicious KVM guest to crash the host

An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register values.

kernel: Heap buffer overflow in firedtv driver

The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking.

PrinterLogic Web Stack versions 19.1.1.13 SP9 and below do not sanitize user input resulting in pre-auth remote code execution.

PrinterLogic Web Stack versions 19.1.1.13 SP9 and below use a hardcoded APP_KEY value, leading to pre-auth remote code execution.

PrinterLogic Web Stack versions 19.1.1.13 SP9 and below deserializes attacker controlled leading to pre-auth remote code execution.

kernel: heap-based buffer overflow in dp_link_settings_write() in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c

dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer.

kernel: memory overwrite in the kernel with potential privileges execution

An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison uses values that are not memory sizes.

Thales Safenet Authentication Client (SAC) for Linux and Windows through 10.7.7 creates insecure temporary hid and lock files allowing a local attacker, through a symlink attack, to overwrite arbitrary files, and potentially achieve arbitrary command execution with high privileges.

kernel: slab out-of-bounds write in decode_data() in drivers/net/hamradio/6pack.c

The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.

kernel: eBPF multiplication integer overflow in prealloc_elems_and_freelist() in kernel/bpf/stackmap.c leads to out-of-bounds write

prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write.

kernel: local user privilege escalation via loop_rw_iter in fs/io_uring.c

loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation.
