kernel: net: mana: Fix TOCTOU double-fetch of hwc_msg_id from DMA buffer

A flaw was found in the Linux kernel's mana network driver. This Time-of-Check to Time-of-Use TOCTOU vulnerability allows a hardware component to modify a message identifier hwcmsgid in Direct Memory Access DMA memory after it has been validated but before it is used. This manipulation bypasses...

In the Linux kernel, the following vulnerabilities have been resolved: usb-storage: alauda: Fixed the uninit-value issue in alaudacheckmedia. Syzbot reported that KMSAN complained about accessing an uninitialized value within the alauda subdriver of usb-storage. Bug: KMSAN: uninit-value in...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: avoid double fput on failed usercopy If the copy back to userland fails for the FASTRPCIOCTLALLOCDMABUFF ioctl, we should not assume that ‘buf-dmabuf’ is still valid. In fact, dmabuffd calls fdinstall before, there...
