Description

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.

This was identified via kmemleak: unreferenced object 0xffff0000205d6878 (size 8): comm "v4l_id", pid 5289, jiffies 4294938580 hex dump (first 8 bytes): 40 d2 49 18 00 00 ff ff @.I..... backtrace (crc d3204599): kmemleak_alloc+0xc8/0xf0 __kvmalloc_node_noprof+0x60c/0x850 v4l2_ctrl_handler_init_class+0x1b4/0x2e8 [videodev] vdec_open+0x1f4/0x788 [meson_vdec] v4l2_open+0x144/0x460 [videodev] chrdev_open+0x1ac/0x500 do_dentry_open+0x3f0/0xfe8 vfs_open+0x68/0x320 do_open+0x2d8/0x9a8 path_openat+0x1d0/0x4f0 do_filp_open+0x190/0x380 do_sys_openat2+0xf8/0x1b0 __arm64_sys_openat+0x13c/0x1e8 invoke_syscall+0xdc/0x268 el0_svc_common.constprop.0+0x178/0x258 do_el0_svc+0x4c/0x70
