CVE-2026-98024

Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

s390/ism: folio_put() after error

dmb->cpu_addr was allocated via folio_alloc(). Use folio_put() instead of kfree() in the error exit of ism_alloc_dmb() to avoid slab allocator corruption.

While at it, reset dmb->cpu_addr after folio_put to avoid unintentional UAF by future callers.
