CVE-2026-99224 Nov 2, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
keys: Protect the type name while describing a key
keyctl_describe_key() must keep the key type's name alive until
kasprintf() has consumed it. The retained key reference keeps the key
and its description alive, but does not pin the module providing its
type. The name is passed to kasprintf() without holding key->sem.
kvasprintf() uses the saved name pointer in two formatting passes, with
a GFP_KERNEL allocation between them.
