In the Linux kernel, the following vulnerability has been resolved: vfio/pci: fixed a potential memory leak in vfiointxenable If vfioirqctxalloc fails, it will lead to a ‘name’ memory leak...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mfd: intelsocpmicbxtwc: Use the IRQ domain for PMIC devices While the idea of adapting the driver to utilize the hierarchy of IRQ chips is correct from a design perspective, the implementation contains flaws. This issue was...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/entry32: CPU buffers are cleared after registers are restored during a 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 mitigatio...

Astra Linux – Vulnerability in Linux 6.1

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 – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: usb: lan78xx: Fixed the double-free issue with interrupt buffer allocation. In lan78xxprobe, the buffer buf was freed twice: once implicitly through usbfreeurbdev-urbintr with the URBFREEBUFFER flag, and again explicitly...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Masking of ring interrupts before the ring stop request is made. The bus cleanup path in DMA mode may trigger a RINGOPSTAT interrupt when the ring is being stopped. Depending on the timing between the completio...
