Description
This security bulletin contains information about 1 vulnerability.
1) Double free (CVE-ID: CVE-2026-64599)
CWE-ID: CWE-415 - Double Free
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a double free in meson_crypto_probe() when handling a failure after partial channel list allocation during device probe. A local user can trigger the vulnerable probe path to cause a denial of service.
The issue was reproduced by forcing the second dma_alloc_attrs() call in the gxl-crypto probe path to fail after partial initialization.
Remediation
Install update from vendor's website.
