Astra Linux – Vulnerability in Linux 5.10, Linux

KGDB and KDB allow read and write access to kernel memory, and therefore should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger, so it is important that the debugger respects the lockdown mode when/if it is triggered. CVSS 3.1 Base Score: 6.7...

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fixed an issue where incomplete state saving occurred in rxerequester. If a send packet is dropped by the IP layer in rxerequester, the call to rxexmitpacket may fail with an error code of -EAGAIN. To recover from this...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Do not generate an interrupt during bus reset. Now that the i2c-i801 driver supports interrupts, setting the KILL bit in an attempt to recover from a timed-out transaction triggers an interrupt. Unfortunately, the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: spacemit: Fix error handling in emactxmemmap The DMA mappings were exposed due to mapping errors. These mappings can now be freed using the existing emacfreetxbuf function...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU implementation of VMWare’s paravirtual RDMA device. This flaw allows a malicious guest driver to allocate and initialize a large number of page tables, which can be used as a ring of descriptors for CQ and async events. This could potentially lead to out-of-bound...
