Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. Prior to versions 6.2.7 and 7.0.0, an attacker who attempted to load a specially crafted Lua script could cause a NULL pointer dereference, resulting in a crash of the redis-server process. This issue was fixed in Redis versions 7.0.0 and...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: rpmpd: Check for a null return from devmkcalloc. Due to the potential failure of the allocation, data-domains might be a NULL pointer, and this could lead to the dereferencing of a NULL pointer later. Therefore, it mig...
