USN-7939-1 linux-azure, linux-azure-5.4 vulnerabilities

Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this t...

EUVD-2025-203790

In the Linux kernel, the following vulnerability has been resolved: most: usb: fix double free on late probe failure The MOST subsystem has a non-standard registration function which frees the interface on registration failures and on deregistration. This unsurprisingly leads to bugs in the MOST...

CVE-2025-68319

The CVE-2025-68319 entry describes a Linux kernel race in netconsole related to iterating over the userdata cg_children list via configfs. The issue arises when concurrent add/remove operations occur while update_userdata() or count_extradata_entries() traverse the same list, potentially causing ...

CVE-2025-68290

The CVE-2025-68290 entry corresponds to a Linux kernel issue in the MOST subsystem where a non-standard registration path frees the interface on registration failures and deregistration. This led to reference underflows, use-after-free, and multiple double-free conditions in MOST/USB-related driv...
