Summary
In the Linux kernel, the following vulnerability has been resolved: ubi: Fix unreferenced object reported by kmemleak in ubi_resize_volume() There is a memory leaks problem reported by kmemleak: unreferenced object 0xffff888102007a00 (size 128): comm "ubirsvol", pid 32090, jiffies 4298464136 (age 2361.231s) hex dump (first 32 bytes): ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ backtrace: [<ffffffff8176cecd>] __kmalloc+0x4d/0x150 [<ffffffffa02a9a36>] ubi_eba_create_table+0x76/0x170 [ubi] [<ffffffffa029764e>] ubi_resize_volume+0x1be/0xbc0 [ubi] [<ffffffffa02a3321>] ubi_cdev_ioctl+0x701/0x1850 [ubi] [<ffffffff81975d2d>] __x64_sys_ioctl+0x11d/0x170 [<ffffffff83c142a5>] do_syscall_64+0x35/0x80 [<ffffffff83e0006a>] entry_SYSCALL_64_after_hwframe+0x46/0xb0 This is due to a mismatch between create and destroy interfaces, and in detail that "new_eba_tbl" created by ubi_eba_create_table() but destroyed by kfree(), while will causing "new_eba_tbl->entries" not freed. Fix it by replacing kfree(new_eba_tbl) with ubi_eba_destroy_table(new_eba_tbl)
