CVE-2022-49830

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/drv: Fix potential memory leak in drm_dev_init()<br /> <br /> drm_dev_init() will add drm_dev_init_release() as a callback. When<br /> drmm_add_action() failed, the release function won&amp;#39;t be added. As the<br /> result, the ref cnt added by device_get() in drm_dev_init() won&amp;#39;t be put<br /> by drm_dev_init_release(), which leads to the memleak. Use<br /> drmm_add_action_or_reset() instead of drmm_add_action() to prevent<br /> memleak.<br /> <br /> unreferenced object 0xffff88810bc0c800 (size 2048):<br /> comm "modprobe", pid 8322, jiffies 4305809845 (age 15.292s)<br /> hex dump (first 32 bytes):<br /> e8 cc c0 0b 81 88 ff ff ff ff ff ff 00 00 00 00 ................<br /> 20 24 3c 0c 81 88 ff ff 18 c8 c0 0b 81 88 ff ff $
