In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: fix memory leak when blob is malformed The bug fix was incomplete; it “replaced” a crash with a memory leak. The old code contained an assignment to ret embedded within a conditional statement; this has been...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: sparx5: switchdev: fixed the possible NULL pointer dereferencing issue. As a possible failure in allocation, devmkzalloc may return a NULL pointer. Therefore, it is better to check for ‘db’ to prevent the dereferencing of a...
