  "details": "In the Linux kernel, the following vulnerability has been resolved:  media: cec: core: Fix kmemleak due to missed rc_free_device() call  The commit dccc0c3ddf8f (\"media: rc: fix race between unregister and urb/irq callbacks\") removed the implicit call to rc_free_device() from rc_unregister_device(). However, the commit missed to remove the NULL assignment of adap-\u003erc that is now causing rc_free_device() to never be called on an allocated rc device.  kmemleak reports following after e.g. dw-hdmi unbind:  unreferenced object 0xffff00010ac10000 (size 4096):   comm \"kworker/u16:1\", pid 39, jiffies 4294897739   hex dump (first 32 bytes):     20 23 4b 0a 01 00 ff ff 08 00 c1 0a 01 00 ff ff   #K.............     08 00 c1 0a 01 00 ff ff 00 00 00 00 00 00 00 00  ................   backtrace (crc e11baccc):     kmemleak_alloc+0x38/0x44     __kmalloc_cache_noprof+0x4a8/0x5e0     rc_allocate_device+0x48/0x2a0     cec_allocate_adapter+0x3ac/0x800     dw_hdmi_cec_probe+0x264/0x634     platform_probe+0xc0/0x188     really_probe+0x4a4/0x8e0     __driver_probe_device+0x2f8/0x440     driver_probe_device+0x60/0x160     __device_attach_driver+0x1a0/0x2a0     bus_for_each_drv+0x100/0x1a0     __device_attach+0x174/0x350     device_initial_probe+0x90/0xb0     bus_probe_device+0x4c/0x120     device_add+0xdec/0x116c     platform_device_add+0x354/0x598  Remove the assignment of adap-\u003erc to NULL to let cec_delete_adapter() free the allocated rc device after last user of the cec device exits to fix the kmemleak.",
