Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: gpio: tegra: Do not call pinctrl for GPIO operations. The functions tegragpiodirectioninput and tegra gpiodirectionoutput already program the GPIO controller’s direction registers directly. Additional calls to pinctrl...

CVE-2026-90098

A flaw was found in the Linux kernel's net: sparx5 driver. The sparx5setrxmode function attempts to acquire a mutex and poll a register while operating in an atomic context, which is not allowed. This improper operation can lead to a "sleep in atomic context" bug, causing system instability or a...

DEBIAN-CVE-2026-98223

In the Linux kernel, the following vulnerability has been resolved: mm: filemap: retain mapped dropbehind folios Fault-around can map ready dropbehind folios without going through the normal page-cache lookup that clears dropbehind. A mapping represents a competing cached user, so retain the foli...

CVE-2026-93815

In the Linux kernel, the following vulnerability has been resolved: net: au1000: move freeirq out of the close-time spinlocked section au1000close calls freeirq while aup-lock is still held with spinlockirqsave. freeirq can sleep because it takes the IRQ descriptor request mutex, so it does not...

CVE-2026-72063: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: gpio: tegra: do not call pinctrl for GPIO direction tegragpiodirectioninput and tegragpiodirectionoutput already program the GPIO controller direction registers directly. The additional pinctrlgpiodirectioninput/output calls do n...

Linux Kernel Security Vulnerabilities

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the IPsec MAC address query in net mlx5e calling a sleep function within atomic context,...

CVE-2026-23134 slab: fix kmalloc_nolock() context check for PREEMPT_RT

In the Linux kernel, the following vulnerability has been resolved: slab: fix kmallocnolock context check for PREEMPTRT On PREEMPTRT kernels, locallock becomes a sleeping lock. The current check in kmallocnolock only verifies we're not in NMI or hard IRQ context, but misses the case where...
