kernel: libceph: prevent potential out-of-bounds reads in handle_auth_done()
In the Linux kernel, the following vulnerability has been resolved: libceph: prevent potential out-of-bounds reads in handleauthdone Perform an explicit bounds check on payloadlen to avoid a possible out-of-bounds access in the callout. idryomov: changelog...
kernel: Linux kernel: Denial of Service in libceph OSD client due to unreset sparse-read state
A flaw was found in the Linux kernel's libceph OSD client. When a connection fault occurs during a sparse read, the sparse-read state is not properly reset. This allows a misbehaving or compromised Ceph OSD server, or a network adversary, to disrupt traffic. As a result, the client can misinterpr...
kernel: libceph: make decode_pool() more resilient against corrupted osdmaps
In the Linux kernel, the following vulnerability has been resolved: libceph: make decodepool more resilient against corrupted osdmaps If the osdmap is maliciously corrupted such that the encoded length of cephpgpool envelope is less than what is expected for a particular encoding version,...
kernel: libceph: replace overzealous BUG_ON in osdmap_apply_incremental()
In the Linux kernel, the following vulnerability has been resolved: libceph: replace overzealous BUGON in osdmapapplyincremental If the osdmap is maliciously corrupted such that the incremental osdmap epoch is different from what is expected, there is no need to BUG. Instead, just declare the...
kernel: libceph: fix potential use-after-free in have_mon_and_osd_map()
A use-after-free vulnerability was found in the Ceph client session initialization in the Linux kernel. The havemonandosdmap function checks map epochs without holding the appropriate locks, racing with concurrent map updates that free the old map. This can result in dereferencing freed memory...

kernel: Linux kernel: libceph null pointer dereference leads to denial of service
A flaw was found in libceph, a component of the Linux kernel. When processing a malformed CRUSH map, if a parent bucket's name exists but its type is missing, a null pointer dereference can occur. This issue can lead to a system crash, resulting in a Denial of Service DoS...

kernel: libceph: refresh auth->authorizer_buf{,_len} after authorizer update
A flaw was found in the libceph component of the Linux kernel. During an authorizer update, if the authorizer is rebuilt, a stale pointer to a freed memory region can be retained. A remote attacker could exploit this by triggering a specific network reconnection, leading to a use-after-free...
kernel: Linux kernel (libceph): Denial of Service due to malformed monitor maps
A flaw was found in the libceph component of the Linux kernel. A remote attacker could send a specially crafted monitor map monmap that advertises zero monitors. This malformed monmap is incorrectly processed as valid, which can lead to a client crash when attempting to open a session. This...

kernel: Linux kernel: libceph stack out-of-bounds write via crafted OSDMap
A flaw was found in libceph in the Linux kernel. A remote attacker, acting as a malicious monitor, could send a specially crafted OSDMap Object Storage Device Map with an overly long pgtemp or pgupmap entry. This could lead to a stack out-of-bounds write, resulting in a kernel bug and potentially...
