In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: fix NULL-dereferencing on non-serdev controllers during suspension Qualcomm ROME controllers can be registered through the Bluetooth interface. In this case, the HCI UART serdev pointer is NULL. A missing sanity...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: fanotify: Validate the return value of mntnsfromdentry before dereferencing it. The function dofanotifymark does not validate whether mntnsfromdentry returns NULL before dereferencing mntns-userns. This causes a NULL pointer...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: brcm80211 – Handle PMKOp allocation failure The kzalloc function in brcmfpmksav3op will return null if physical memory runs out. As a result, if we dereference the null value, a null pointer dereference bug will occur. Retu...
