Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: genirq/irqdesc: Prevent use-after-free in irqfindatorafter The irqfindatorafter function dereferences the interrupt descriptor returned by mtfind, without holding the sparseirqlock or RCU read lock. This means that the descriptor...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: A WARN message is generated on vNMI when an NMI window is requested, provided that the NMIs are effectively masked. This occurs only if the vCPU is already handling an NMI. KVM’s approach for handling simultaneous NMIs ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: mt76: mt7921e: Fix use-after-free in freeirq From the commit “a304e1b82808” “PATCH Debug shared irqs”, there is a test to ensure that the shared irq handler should be able to handle unexpected events after deregistration. I...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys – cancels delayed work only in case of GPIO. The gpiokeys module can accept gpios or interrupts. The module initializes delayed work only in case of gpios and is only used if the debounce timer is not used...

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: octeontx2-af: Separate handlers are used for interrupts. The interrupt vector from PF to AF, and the interrupt vector from VF to AF, both use the same interrupt handler. This causes a race condition. When two interrupts are raise...

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 – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: spi: hisi-sfc-v3xx: Return IRQNone if no interrupts were detected Return IRQNone from the interrupt handler when no interrupt was detected. This is because an empty interrupt will cause a null pointer error. "Unable to handle...
