CVE-2026-68223
Estado: RecibidaSin puntuar—
In the Linux kernel, the following vulnerability has been resolved:
media: meson: vdec: Fix memory leak in error path of vdec_open
The vdec_open() function previously jumped directly to err_m2m_release when vdec_init_ctrls() failed, skipping release of the m2m context. This caused a resource leak.
Fix it by introducing a proper err_m2m_ctx_release label that calls v4l2_m2m_ctx_release(sess->m2m_ctx) before releasing the m2m device.
