Description
In the Linux kernel, the following vulnerability has been resolved:
safesetid: check size of policy writes
syzbot attempts to write a buffer with a large size to a sysfs entry with writes handled by handle_policy_update(), triggering a warning in kmalloc.
Check the size specified for write buffers before allocating.
[PM: subject tweak]
