Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the libceph component of the Linux kernel where the sparse-read state is not properly reset in the osd fault() function when a connection fault occurs. This can lead to the OSD client misinterpreting new replies as continuations of old, incomplete ones, potentially causing the sparse-read machinery to enter an unrecoverable failure state and resulting in loops. The issue arises when a connection is lost mid-payload or the sparse-read state machine returns an error. The osd fault() function is responsible for handling connection faults, and the fix involves resetting the sparse-read state within this function to ensure retries start from a clean state.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
