In the Linux kernel, the following vulnerability has been resolved: PCI: pnvphp: Clean up allocated IRQs on unplug When the root of a nested PCIe bridge configuration is unplugged, the pnvphp driver leaks the allocated IRQ resources for the child bridges’ hotplug event notifications, resulting in...

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

In the Linux kernel, the following vulnerability has been resolved: usb: net: sierra: check for no status endpoint The driver checks whether it has three endpoints, as well as endpoints for bulk in-and-out operations. However, it does not check whether the third endpoint is an interrupt input. Th...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: spi: tegra: A memory leak has been fixed in tegraslinkprobe. In tegraslinkprobe, when platformgetirq fails, it directly returns from the function with an error code, resulting in a memory leak. This issue can be addressed by...

In the Linux kernel, the following vulnerability has been resolved: ALSA: mts64: fix possible null-ptr-defer in sndmts64interrupt I got a null-ptr-defer error report when I do the following tests on the qemu platform: make defconfig and CONFIGPARPORT=m, CONFIGPARPORTPC=m, CONFIGSNDMTS64=m Then...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm: bridge: anx7625: Fixed NULL pointer dereferencing due to early interrupt requests. If an interrupt occurs before resource initialization is complete, the interrupt handler/worker may access uninitialized data, such as the I2...

In the Linux kernel, the following vulnerability has been resolved: powerpc/52xx: Fixed a resource leak in the error handling path. The error handling path of mpc52xxlpbfifoprobe contains a requestirq call, which is not accompanied by a corresponding freeirq call. We have added the missing call,...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: ks8851: Packets are queued in the IRQ handler instead of being disabled during the BH handling process. Currently, the driver uses localbhdisable/localbhenable in its IRQ handler to avoid triggering netrxaction in the softir...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: remoteproc: mediatek: Ensure that the IPI buffer fits within the L2TCM.
