Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue exists in the erofs component where compressed folios for ztailpacking pclusters are not validated before being added to I/O chains. This can lead to a NULL pointer dereference within the z erofs decompress pcluster() function if the system assumes the folios are already valid. This condition may occur if a fatal signal is received while the read mapping folio() function is executing, causing a failure to retrieve inline data.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
