Description

In the Linux kernel, the following vulnerability has been resolved: fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion The first kiocb_set_cancel_fn() argument may point at a struct kiocb that is not embedded inside struct aio_kiocb. With the current code, depending on the compiler, the req->ki_ctx read happens either before the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such that it is guaranteed that the IOCB_AIO_RW test happens first.

Affected configurations

• linux linux kernel (>= 4.19.308 < 4.19.312) • linux linux kernel (>= 5.4.270 < 5.4.274) • linux linux kernel (>= 5.10.211 < 5.10.215) • linux linux kernel (>= 5.15.150 < 5.15.154) • linux linux kernel (>= 6.1.80 < 6.1.84) • linux linux kernel (>= 6.6.19 < 6.6.24) • linux linux kernel (>= 6.7.7 < 6.7.12) • linux linux kernel 6.8 • debian debian linux 10.0
