GHSA-C982-MG4H-7C8X

Vulnerability from github – Published: 2025-02-27 03:34 – Updated: 2025-10-23 15:30

Details

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

KEYS: trusted: dcp: fix improper sg use with CONFIG_VMAP_STACK=y

With vmalloc stack addresses enabled (CONFIG_VMAP_STACK=y) DCP trusted keys can crash during en- and decryption of the blob encryption key via the DCP crypto driver. This is caused by improperly using sg_init_one() with vmalloc'd stack buffers (plain_key_blob).

Fix this by always using kmalloc() for buffers we give to the DCP crypto driver.

Severity ?

5.5 (Medium)
