CVE-2026-98636

The Linux kernel contains a vulnerability in the squashfs module where mounting an abnormal SquashFS image (with COMP_OPTS set to 1 but a dictionary size of 0) triggers a shift-out-of-bounds error. This occurs because the shift exponent $n$ becomes -1, leading to an invalid shift operation during...
