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...

CVE-2026-89953

CVE-2026-89953 is a memory leak in the Linux kernel's mtdoops module. The root cause is that mtdoops_notify_remove() detaches from the backing MTD device but leaves the oops_page_used bitmap allocated. When the same MTD device is subsequently re-registered, the add path allocates a new bitmap and...
