kernel: Double free in the inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c

The inetcskclonelock function in net/ipv4/inetconnectionsock.c in the Linux kernel allows attackers to cause a denial of service double free or possibly have unspecified other impact by leveraging use of the accept system call. An unprivileged local user could use this flaw to induce kernel memor...

Apple MacOS 32-Bit Syscall Exit Kernel Register Leak(CVE-2017-2509)

The XNU kernel, when compiled for a x86-64 CPU, can run 32-bit x86 binaries in compatibility mode. 32-bit binaries use partly separate syscall entry and exit paths. To return to userspace, unixsyscall in bsd/dev/i386/systemcalls.c calls threadexceptionreturn in osfmk/x8664/locore.s, which in turn...
