CVE-2026-90067

In the Linux kernel, the following vulnerability has been resolved: libceph: validate banner payload length When parsing the Ceph messenger v2 protocol banner, the payloadlen field is decoded from the banner prefix. If a client sends a banner with a payloadlen of 0, the kernel sets up a 0-length...

SUSE CVE-2026-89990

In the Linux kernel, the following vulnerability has been resolved: ceph: lock mutex in cephmdscheckaccess MDS session OPEN handling replaces mdsc-scapauths under mdsc-mutex, freeing the previous array and its strings. cephmdscheckaccess traverses this array without holding the mutex. A concurren...

SUSE CVE-2026-90042

In the Linux kernel, the following vulnerability has been resolved: ceph: properly decrypt filenames in vmalloc buffers The fscrypt subsystem uses the scatterlist crypto API, inheriting its requirement that any buffers are in the linear mapping region. However, the messenger client uses kvmalloc ...

CVE-2026-90067

CVE-2026-90067 is a Linux kernel vulnerability in the Ceph messenger v2 protocol implementation (net/ceph/messenger_v2.c). When parsing the msgr2 protocol banner, a client sending a payload_len of 0 causes the kernel to set up a 0-length socket read , violating a state-machine invariant and trigg...

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...
