CVE-2023-52886

The CVE-2023-52886 entry describes a race in the Linux kernel USB core where hub_port_init() can overwrite udev->descriptor while read_descriptors() (sysfs.c) is reading it, enabling a slab-out-of-bounds read (KASAN) observed in syzbot. The root cause is a race between read_descriptors() and h...
