Descriptions

A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream "x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()" commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped.

Se descubiró un error de backporting en el kernel de Linux estable/a largo plazo en sus versiones 4.4.x hasta 4.4.190, versiones 4.9.x hasta 4.9.190, versiones 4.14.x hasta 4.14.141, versiones 4.19.x hasta 4.19.69 y versiones 5.2.x hasta 5.2 .11. El uso incorrecto del commit "x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()" aguas arriba reintrodujo la vulnerabilidad Spectre que se pretendía eliminar. Esto ocurrió porque el proceso de backport depende de que cherry recolecte commits específicas y porque se intercambiaron dos líneas de código (ordenadas correctamente).
