Linux Kernel Security Vulnerabilities

The Linux kernel version 5.16 contains a security vulnerability. This vulnerability arises from the fact that SORESERVEMEM is not limited to TCP sockets, and no upper limit is set. This may lead to concurrent operations on UDP sockets damaging skforwardalloc and memcg accounting, or causing...

Astra Linux – Vulnerability in libxml2

In libxml2 versions before 2.9.14, several buffer handling functions in buf.c xmlBuf and tree.c xmlBuffer do not check for integer overflows. This can lead to out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software that uses libxml2’s...
