kernel: use-after-free related to leaf anon_vma double reuse
A memory leak flaw with use-after-free capability was found in the Linux kernel. The VMA mm/rmap.c functionality in the ismergeableanonvma function continuously forks, using memory operations to trigger an incorrect reuse of leaf anonvma. This issue allows a local attacker to crash the system...

Authorization Bypass
openssl is vulnerable to Authorization Bypasses. Invalid certificate policies in leaf certificates are ignored by OpenSSL, allowing malicious CA to bypass policy checking. Policy processing is disabled by default, but can be enabled by passing the '-policy' argument to command line utilities or...
