CVE ID : CVE-2026-23227<\/p>\n
Published : Feb. 18, 2026, 4:22 p.m. | 37\u00a0minutes ago<\/p>\n
Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/exynos: vidi: use ctx->lock to protect struct vidi_context member variables related to memory alloc\/free<\/p>\n
Exynos Virtual Display driver performs memory alloc\/free operations
\nwithout lock protection, which easily causes concurrency problem.<\/p>\n
For example, use-after-free can occur in race scenario like this:
\n“`
\n\tCPU0\t\t\t\tCPU1\t\t\t\tCPU2
\n\t—-\t\t\t\t—-\t\t\t\t—-
\n vidi_connection_ioctl()
\n if (vidi->connection) \/\/ true
\n drm_edid = drm_edid_alloc(); \/\/ alloc drm_edid
\n …
\n ctx->raw_edid = drm_edid;
\n …
\n\t\t\t\t\t\t\t\tdrm_mode_getconnector()
\n\t\t\t\t\t\t\t\t drm_helper_probe_single_connector_modes()
\n\t\t\t\t\t\t\t\t vidi_get_modes()
\n\t\t\t\t\t\t\t\t if (ctx->raw_edid) \/\/ true
\n\t\t\t\t\t\t\t\t drm_edid_dup(ctx->raw_edid);
\n\t\t\t\t\t\t\t\t if (!drm_edid) \/\/ false
\n\t\t\t\t\t\t\t\t …
\n\t\t\t\tvidi_connection_ioctl()
\n\t\t\t\t if (vidi->connection) \/\/ false
\n\t\t\t\t drm_edid_free(ctx->raw_edid); \/\/ free drm_edid
\n\t\t\t\t …
\n\t\t\t\t\t\t\t\t drm_edid_alloc(drm_edid->edid)
\n\t\t\t\t\t\t\t\t kmemdup(edid); \/\/ UAF!!
\n\t\t\t\t\t\t\t\t …
\n“`<\/p>\n
To prevent these vulns, at least in vidi_context, member variables related
\nto memory alloc\/free should be protected with ctx->lock.<\/p>\n
