Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the SquashFS ReadBlock function. An attacker can cause disclosure of heap memory contents by providing a specially crafted SquashFS archive with a manipulated node.Offset value, which bypasses fragment bounds check...

CVE-2026-48104

7-Zip (versions 9.18–26.00) contains an uninitialized heap read in the SquashFS archive handler. A sparsely populated index array causes _blockToNode to be allocated for all metadata blocks but only populated when an inode crosses a block boundary; images with few inodes spanning many blocks leav...
