In the Linux kernel, the following vulnerability has been resolved: macintosh/via-macii: Fixed “BUG: sleeping function called from invalid context”. The via-macii ADB driver calls requestirq after disabling hard interrupts. However, disabling interrupts is not necessary here, because the VIA shif...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: x86/entry32: CPU buffers are cleared after register restoration in NMI return. Currently, CPU buffers are cleared after a call to excnmi, but before the register state is restored. This may be acceptable for MDS mitigation, but n...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Networks: Ethernet, ARC, EMAC: Quiesce interrupts before requesting the IRQ. Normal RX/TX interrupts are enabled later, in arcemacopen. Therefore, the probe should not detect any interrupt deliveries in the usual case. However, t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM – Fix for a panic occurring on an out-of-bounds guest IRQ. Since the guestIRQ comes from the KVMIRQFD API call, it may trigger a crash in svmupdatepiirte, due to an out-of-bounds access. Crash output: pid: 22218 task:...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: ACPI: GTDT: Do not corrupt interrupt mappings during watchdog probe failures When the driver probe fails due to invalid firmware properties, the GTDT driver unmaps the interrupt that was previously mapped. However, it never check...
