{"apiVersion":"1.0","identifier":"CVE-2026-74426","description":"In the Linux kernel, the following vulnerability has been resolved: afs: fix NULL pointer dereference in afs_get_tree() afs_alloc_sbi() uses kzalloc for memory allocation. And, if ctx->dyn_root is not null, as->cell and as->volume are null. In trace_afs_get_tree() they are dereferenced.
