Effective Fuzzing: A Dav1d Case Study

Guest post by Nick Galloway, Senior Security Engineer, 20% time on Project Zero Late in 2023, while working on a 20% project with Project Zero, I found an integer overflow in the dav1d AV1 video decoder. That integer overflow leads to an out-of-bounds write to memory. Dav1d 1.4.0 patched this, an...

In smsExtractCbLanguage of smsCellBroadcast.c, there is a possible out of bounds read due to a missing bounds check. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation...

Fuzzing µC/OS protocol stacks, Part 3: TCP/IP server fuzzing, implementing a TAP driver

This is the final post in the three-part series that details techniques I used to fuzz two µC/OS protocol stacks: µC/TCP-IP and µC/HTTP-server. The first post highlighted code modifications necessary for developing a fuzzing harness tailored for the µC/HTTP-server. The second discussed a techniqu...

CVE-2022-48869

CVE-2022-48869 concerns the Linux kernel gadgetfs USB driver. The issue arises from a race between gadgetfs_fill_super() (mount path) and gadgetfs_kill_sb() (unmount path), where the_device could be deallocated while gadgetfs_fill_super() still uses it, resulting in a use-after-free. The provided...
