An input validation issue in WhatsApp Desktop versions prior to v0.3.4932 could have allowed Cross-Site Scripting (XSS) upon clicking on a link from a specially crafted live location message.
The ppp package in Ubuntu contains a patch to load the ppp_generic kernel module when it's not built by default in the Linux kernel. The patch has a vulnerability that allows an attacker to influence the behavior of the modprobe binary using MODPROBE_OPTIONS environment variable. This vulnerability leads to arbitrary file read or arbitrary kernel module loading.
A flaw was found in the Linux kernels SELinux LSM hook implementation, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing.
In the Linux kernel, get_raw_socket() in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
Mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure.
A flaw was found in the Linux kernel's ext4_unlink function. An attacker could corrupt memory or escalate privileges when deleting a file from a recently unmounted specially crafted ext4 filesystem, including local, USB, and iSCSI.
Improper conditions check in voltage settings for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege and/or information disclosure via local access.
An untrusted domain with access to a physical device can DMA into host memory, leading to privilege escalation.
