UBUNTU-CVE-2026-98770

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: midi2: Fix the jack descriptor array sizes The jack in/out descriptor arrays in struct fmidi2usbconfig have the size of MAXCABLES, which look reasonable -- but it turned out to be incorrect. Namely, the entries for...

Chimera

Chimera Hardware Emulation & Proximity Exploitation Why Hak5 gear is heavy and obvious. My phone has a full Linux kernel in it, so I made it do the same job — HID emulation, RNDIS, mass storage, the whole thing — straight through ConfigFS. No extra hardware. No cables dangling out of a bag. Plug...

CVE-2026-98770

The Linux kernel contains a vulnerability in the usb gadget midi2 component. Specifically, the jack_ins and jack_outs descriptor arrays in struct f_midi2_usb_config were incorrectly sized to MAX_CABLES. Because entries are added from both inputs and outputs during loop cycles, the arrays actually...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: frndis: Protect RNDIS options with a mutex The class/subclass/protocol options are susceptible to race conditions, as they can be accessed concurrently through configfs. A mutex should be used to protect these option...

CVE-2026-90184

A flaw was found in the Linux kernel's nullblk module. A race condition exists where configfs attribute updates can occur concurrently with the nullblk device setup. This lack of synchronization can lead to incorrect device configuration, resulting in a system crash Denial of Service or failure t...

CVE-2026-90189

A flaw was found in the Linux kernel's nullblk component. A race condition can occur when the configfs subsystem is registered before default devices are created. This allows a local attacker, by performing a specific sequence of operations, to trigger a Use-After-Free UAF vulnerability. This cou...

CVE-2026-90185

A flaw was found in the Linux kernel's nullblk module. This vulnerability occurs because concurrent operations on configfs attributes are not properly synchronized. A local user could exploit this timing issue to modify data during device setup, leading to an out-of-bounds memory access. This cou...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: PCI: Endpoint – Avoid creating sub-groups asynchronously Asynchronous creation of sub-groups by a delayed operation could lead to a NULL pointer dereference when the driver directory is removed before the operation completes. The...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fsubset: Fixed an unbalanced reference count in gethfree. gethalloc increments the reference count, but gethfree fails to decrement it. This causes issues when configuring attributes via configfs after unlinking the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: scsi: target: Fixed recursive locking in configfsopenfile. In flushwritebuffer, the variable &p-fragsem is acquired, and then the loaded store function is called—specifically, targetcoreitemdbrootstore. This function calls...
