CVE-2026-90042

CVE-2026-90042 affects the Linux kernel's Ceph filesystem client . The root cause is that the messenger client uses kvmalloc() to allocate message buffers, which can place them in the vmalloc() region when physical memory fragmentation prevents a sufficiently large kmalloc(). The fscrypt subsyste...
