Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR

A flaw was found in the way the Linux kernel derived the IP ID field from a partial kernel space address returned by a nethashmix function. A remote user could observe this IP ID field to extract the kernel address bits used to derive its value, which may result in leaking the hash key and...

CVE-2019-19126

A vulnerability was discovered in glibc where the LDPREFERMAP32BITEXEC environment variable is not ignored when running binaries with the setuid flag on x8664 architectures. This allows an attacker to force system to utilize only half of the memory making the system think the software is 32-bit...
