Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel's libceph component where the
decode pool() function may be susceptible to out-of-bounds reads. This can occur if an osdmap is corrupted, specifically when the encoded length of a ceph pg pool envelope is less than the expected value for a particular encoding version. The issue arises because the existing bounds check relies on this potentially manipulated length value. The patch introduces explicit bounds checks for each field during decoding or skipping operations to address this.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
