Description

In the Linux kernel, the following vulnerability has been resolved: powerpc/lib: Validate size for vector operations Some of the fp/vmx code in sstep.c assume a certain maximum size for the instructions being emulated. The size of those operations however is determined separately in analyse_instr(). Add a check to validate the assumption on the maximum size of the operations, so as to prevent any unintended kernel stack corruption.

Affected configurations

• linux linux kernel (< 4.19.307) • linux linux kernel (>= 4.20 < 5.4.269) • linux linux kernel (>= 5.5 < 5.10.210) • linux linux kernel (>= 5.11 < 5.15.149) • linux linux kernel (>= 5.16 < 6.1.77) • linux linux kernel (>= 6.2 < 6.6.16) • linux linux kernel (>= 6.7 < 6.7.4)
