CVE-2025-22033

Summary

[CVE-2025-22033]: A vulnerability in the Linux kernel, specifically in the do_compat_alignment_fixup() function, has been addressed. This issue occurs when the function returns NULL after do_alignment_t32_to_handler() fails to fix up alignment faults for certain instructions. If this happens, the kernel will panic due to a NULL pointer dereference. Without the patch, this results in an internal error, as evidenced by the provided stack trace. The bug affects the Debian 6.1.128-1 distribution, and modules such as igb, i2c, and xhci_hcd are among those linked in.
