SWAPGS Attack — New Speculative Execution Flaw Affects All Modern Intel CPUs

A new variant of the Spectre Variant 1 side-channel vulnerability has been discovered that affects all modern Intel CPUs, and probably some AMD processors as well, which leverage speculative execution for high performance, Microsoft and Red Hat warned. Identified as CVE-2019-1125, the vulnerabili...

The vulnerability of the `show_opcodes` function in the Linux operating system’s kernel allows a hacker to disclose protected information.

The vulnerability of the showopcodes function in the Linux operating system’s kernel is caused by errors in the input data validation process. Exploiting this vulnerability can allow an attacker to gain access to the protected information stored in the kernel...

FreeBSD : FreeBSD -- System call kernel data register leak (683c714d-2d91-11e9-bf3e-a4badb2f4699)

The callee-save registers are used by kernel and for some of them %r8, %r10, and for non-PTI configurations, %r9 the content is not sanitized before return from syscalls, potentially leaking sensitive information. Impact : Typically an address of some kernel data structure used in the syscall...
