CVE-2024-35815

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: fs/aio: verifique IOCB_AIO_RW antes de la conversión de struct aio_kiocb. El primer argumento kiocb_set_cancel_fn() puede apuntar a una estructura kiocb que no está incrustada dentro de struct aio_kiocb. Con el código actual, dependiendo del compilador, la lectura req->ki_ctx ocurre antes de la prueba IOCB_AIO_RW o después de esa prueba. Mueva la lectura req->ki_ctx de modo que se garantice que la prueba IOCB_AIO_RW se realice primero.

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.

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
