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...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: libceph: Potential out-of-bounds reads in processmessageheader have been prevented. If the message frame is maliciously corrupted in such a way that the length of the control segment becomes shorter than the size of the message...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: libceph: Use u32 for non-negative values in cephmonmapDecode This patch fixes unnecessary implicit conversions that change the signedness of bloblen and nummon in cephmonmapDecode. Currently, bloblen and nummon are signed int...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: libceph: Defined and enforced the CEPHMAXKEYLEN. When decoding the key, verify that the key material fits into a fixed-size buffer in processauthdone, and that its length is reasonable. The new CEPHMAXKEYLEN check replaces the...

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential out-of-bounds access in cephhandleauthreply This patch fixes an out-of-bounds access in cephhandleauthreply that can be triggered by a message of type CEPHMSGAUTHREPLY. In cephhandleauthreply, the value of...

CVE-2026-43407

A flaw was found in the libceph component of the Linux kernel. A remote attacker could send a specially crafted CEPHMSGAUTHREPLY message with a large payloadlen value. This could lead to an integer overflow, causing an out-of-bounds memory access. This vulnerability could result in memory...

CVE-2026-43406

A flaw was found in libceph in the Linux kernel. A remote attacker could exploit this vulnerability by sending a maliciously crafted message frame. This manipulation, either by corrupting the control segment length or disguising a different frame as a message frame, can cause out-of-bounds reads...

CVE-2026-43405

A flaw was found in the libceph component of the Linux kernel. This vulnerability occurs in the cephmonmapdecode function due to incorrect handling of non-negative values, where int variables are used instead of u32 for bloblen and nummon. An attacker could exploit this by sending a specially...

CVE-2026-43304
