CVE-2023-52682

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue arises when an inode is compressed but not encrypted, and the system fails to call f2fs wait on block writeback() to wait for GCed page writeback in the IPU write path. This can lead to old data overriding new data due to out-of-order GC and common IO. The problem involves several functions, including f2fs gc, do garbage collect, gc data segment, move data block, f2fs submit page write, f2fs write single data page, f2fs do write data page, f2fs inplace write data, f2fs submit page bio, and f2fs read end io.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
