CVE-2026-74426

In the Linux kernel, the following vulnerability has been resolved: afs: fix NULL pointer dereference in afsgettree afsallocsbi uses kzalloc for memory allocation. And, if ctx-dynroot is not null, as-cell and as-volume are null. In traceafsgettree they are dereferenced. KASAN error message: KASAN...

CVE-2026-74426

CVE-2026-74426 (Linux kernel) : A NULL pointer dereference in the AFS filesystem during afs_get_tree() was fixed. The root cause involved afs_alloc_sbi() using kzalloc and, if ctx->dyn_root is non-null, as->cell and as->volume being null, leading to dereferencing these fields in trace_af...
