Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Disable IRQs before initfn for non-boot CPUs. Disable IRQs before initfn for non-boot CPUs during hotplug operations, in order to silence such warnings and also to avoid potential errors due to unexpected interrupts...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: um: time-travel: fix time corruption In the “basic” time-travel mode without =inf-cpu or =ext, we still encounter timer interrupts. These can occur at arbitrary times, for example, while inside the timerread function, which simpl...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: tty: serial: imx: disable Ageing Timer interrupt request irq There might be pending USR interrupts before requesting the IRQ. However, the uartaddoneport function has not been executed, which could lead to a kernel panic. 0.79566...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: clockevents: Added missing resets to the nexteventforced flag. The mechanism used to prevent timer interrupts from being missed caused issues when the nexteventforced flag wasn’t reset in certain situations: - When the state of t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: macb: Use devconsumeskbany to free TX SKBs The napiconsumeskb function is not intended to be called in a disabled IRQ context. However, after commit 6bc8a5098bf4 “net: macb: Fix txptrlock locking”, the freeing of TX SKBs is...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sfc: Fixed the TX channel offset when using legacy interrupts. In the legacy interrupt mode, the txchanneloffset was hardcoded to 1, but this is incorrect if efxsepparatetxChannels is set to false. In that case, the offset is 0...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: irqchip/gic-v3: Do not enable IRQs when handling spurious interrupts. The following error occurred while running our 4.19 kernel with the pseudo-NMI patches backported to it: 14.816231 ------------ Cut here ------------...

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

In the Linux kernel, the following vulnerability has been resolved: BPF, sockmap: Prevent lock inversion deadlock in mapdeleteelem operation. The syzkaller started using corpuses where a BPF tracing program deletes elements from a sockmap/sockhash map. Since BPF tracing programs can be invoked fr...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: media: rkisp1: Fixed handling of IRQs due to shared interrupts. The driver requests interrupts using IRQFSHARED, so the interrupt handlers can be called at any time. If such a call occurs while the ISP is powered down, the SoC wi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: pinctrl: mcp23s08: Disables all pin interrupts during probing The chip being probed may have the interrupt-on-change feature enabled on some of its pins, for example after a reboot. This can cause the chip to generate interrupts...

CVE-2026-43324

A flaw was found in the Linux kernel's dummy-hcd driver. This vulnerability stems from an interrupt synchronization error where emulated interrupts can occur after the system attempts to synchronize interrupt handlers. This timing issue creates a race condition, potentially allowing a callback...

SUSE CVE-2025-40048

In the Linux kernel, the following vulnerability has been resolved: uiohvgeneric: Let userspace take care of interrupt mask Remove the logic to set interrupt mask by default in uiohvgeneric driver as the interrupt mask value is supposed to be controlled completely by the user space. If the mask b...

EUVD-2026-28608

In the Linux kernel, the following vulnerability has been resolved: USB: dummy-hcd: Fix interrupt synchronization error This fixes an error in synchronization in the dummy-hcd driver. The error has a somewhat involved history. The synchronization mechanism was introduced by commit 7dbd8f4cabd9...

CVE-2026-43351

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Eagerly init vgic dist/redist on vgic creation If vgicallocateprivateirqslocked fails for any odd reason, we exit kvmvgiccreate early, leaving dist-rdregions uninitialised. kvmvgicdistdestroy then comes along and walk...
