Threats tagged 'ghsa-8x93-8jfm-fwvw'

A vulnerability in the Linux kernel's s390/ism subsystem was resolved involving improper memory deallocation after an error in ism_alloc_dmb(). The issue was caused by using kfree() instead of folio_put() to free memory, which could lead to slab allocator corruption and potential use-after-free (UAF) conditions. The fix involves using folio_put() and resetting the pointer to avoid unintentional UAF by future callers.
