CVE-2026-89717

This vulnerability affects the Linux kernel's zram module. In zram_destroy_comps(), all compressors are reset to NULL , including the primary compressor , leaving the device in an invalid state. This can lead to a NULL pointer dereference when comp_algorithm_show() calls strcmp() on the NULL prim...
