n the Linux kernel, the following vulnerability has been resolved: bpf: Fix array bounds error with may_goto may_goto uses an additional 8 bytes on the stack, which causes the interpreters[] array to go out of bounds when calculating index by stack_size. 1. If a BPF program is rewritten, re-evaluate the stack size. For non-JIT cases, reject loading directly. 2. For non-JIT cases, calculating interpreters[idx] may still cause out-of-bounds array access, and just warn about it. 3. For jit_requested cases, the execution of bpf_func also needs to be warned. So move the definition of function __bpf_prog_ret0_warn out of the macro definition CONFIG_BPF_JIT_ALWAYS_ON.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bpf: Corrección del error de los límites de la matriz con may_goto. may_goto utiliza 8 bytes adicionales en la pila, lo que provoca que la matriz interpreters[] salga de los límites al calcular el índice mediante stack_size. 1. Si se reescribe un programa BPF, reevalúe el tamaño de la pila. En casos que no sean JIT, rechace la carga directamente. 2. En casos que no sean JIT, el cálculo de interpreters[idx] puede seguir provocando un acceso a la matriz fuera de los límites y simplemente advertir al respecto. 3. En casos con jit_requested, también se debe advertir la ejecución de bpf_func. Por lo tanto, mueva la definición de la función __bpf_prog_ret0_warn fuera de la definición de la macro CONFIG_BPF_JIT_ALWAYS_ON.
