Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: Fix memory leak in rtw88_usb
Kmemleak shows the following leak arising from routine in the usb probe routine:
unreferenced object 0xffff895cb29bba00 (size 512): comm "(udev-worker)", pid 534, jiffies 4294903932 (age 102751.088s) hex dump (first 32 bytes): 77 30 30 30 00 00 00 00 02 2f 2d 2b 30 00 00 00 w000...../-+0... 02 00 2a 28 00 00 00 00 ff 55 ff ff ff 00 00 00 ..*(.....U...... backtrace: [] kmalloc_trace+0x26/0x90 [] rtw_usb_probe+0x2f1/0x680 [rtw_usb] [] usb_probe_interface+0xdd/0x2e0 [usbcore] [] really_probe+0x18e/0x3d0 [] __driver_probe_device+0x78/0x160 [] driver_probe_device+0x1f/0x90 [] __driver_attach+0xbf/0x1b0 [] bus_for_each_dev+0x70/0xc0 [] bus_add_driver+0x10e/0x210 [] driver_register+0x55/0xf0 [] usb_register_driver+0x88/0x140 [usbcore] [] do_one_initcall+0x43/0x210 [] do_init_module+0x4a/0x200 [] __do_sys_finit_module+0xac/0x120 [] do_syscall_64+0x56/0x80 [] entry_SYSCALL_64_after_hwframe+0x46/0xb0
The leak was verified to be real by unloading the driver, which resulted in a dangling pointer to the allocation.
The allocated memory is freed in rtw_usb_intf_deinit().
