"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: meson: vdec: Fix memory leak in error path of vdec_open\n\nThe vdec_open() function previously jumped directly to\nerr_m2m_release when vdec_init_ctrls() failed, skipping\nrelease of the m2m context. This caused a resource leak.\n\nFix it by introducing a proper err_m2m_ctx_release label\nthat calls v4l2_m2m_ctx_release(sess->m2m_ctx) before\nreleasing the m2m device.\n\nThis was identified via kmemleak:\nunreferenced object 0xffff0000205d6878 (size 8):\n comm \"v4l_id\", pid 5289, jiffies 4294938580\n hex dump (first 8 bytes):\n 40 d2 49 18 00 00 ff ff @.I.....\n backtrace (crc d3204599):\n kmemleak_alloc+0xc8/0xf0\n __kvmalloc_node_noprof+0x60c/0x850\n v4l2_ctrl_handler_init_class+0x1b4/0x2e8 [videodev]\n vdec_open+0x1f4/0x788 [meson_vdec]\n v4l2_open+0x144/0x460 [videodev]\n chrdev_open+0x1ac/0x500\n do_dentry_open+0x3f0/0xfe8\n vfs_open+0x68/0x320\n do_open+0x2d8/0x9a8\n path_openat+0x1d0/0x4f0\n do_filp_open+0x190/0x380\n do_sys_openat2+0xf8/0x1b0\n __arm64_sys_openat+0x13c/0x1e8\n invoke_syscall+0xdc/0x268\n el0_svc_common.constprop.0+0x178/0x258\n do_el0_svc+0x4c/0x70"
