Vulnerability from github – Published: 2025-12-30 15:30 – Updated: 2025-12-30 15:30

Details

In the Linux kernel, the following vulnerability has been resolved:

crypto: hisilicon/zip - fix mismatch in get/set sgl_sge_nr

KASAN reported this Bug:

[17619.659757] BUG: KASAN: global-out-of-bounds in param_get_int+0x34/0x60
[17619.673193] Read of size 4 at addr fffff01332d7ed00 by task read_all/1507958
...
[17619.698934] The buggy address belongs to the variable:
[17619.708371]  sgl_sge_nr+0x0/0xffffffffffffa300 [hisi_zip]

There is a mismatch in hisi_zip when get/set the variable sgl_sge_nr. The type of sgl_sge_nr is u16, and get/set sgl_sge_nr by param_get/set_int.

Replacing param_get/set_int to param_get/set_ushort can fix this bug.
