SUSE CVE-2026-52955

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential out-of-bounds access in crushdecode A message of type CEPHMSGOSDMAP containing a crush map with at least one bucket has two fields holding the bucket algorithm. If the values in these two fields differ, an...

SUSE CVE-2026-52957

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential null-ptr-deref in decodechooseargs A message of type CEPHMSGOSDMAP contains an OSD map that itself contains a CRUSH map. When decoding this CRUSH map in crushdecode, an array of maxbuckets CRUSH buckets is...

CVE-2026-52956

A flaw was found in the Linux kernel's libceph module. A remote attacker could trigger an out-of-bounds memory access in the cephxdecrypt function by sending a specially crafted message frame of type FRAMETAGAUTHREPLYMORE with a small ciphertext length. This vulnerability arises because the...

CVE-2026-52954

A flaw was found in the Linux kernel's libceph component. A remote attacker could send a specially crafted CEPHMSGOSDMAP message containing a corrupted CRUSH map. If this map includes two crushchooseargmaps with identical indices, it triggers an assertion failure, leading to a kernel bug and a...

CVE-2026-52958

A flaw was found in the Linux kernel's libceph component. This vulnerability, located within the osdmapdecode function, can lead to an out-of-bounds memory access. A remote attacker could exploit this by sending a specially crafted and corrupted osdmap message, where the maxosd value exceeds the...
