In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: Fix memory leak in management tx In the current logic, memory is allocated for storing the MSDU context during management packet TX but this memory is not being freed during management TX completion. Similar leaks are seen in the management TX cleanup logic. Kmemleak reports this problem as below, unreferenced object 0xffffff80b64ed250 (size 16): comm "kworker/u16:7", pid 148, jiffies 4294687130 (age 714.199s) hex dump (first 16 bytes): 00 2b d8 d8 80 ff ff ff c4 74 e9 fd 07 00 00 00 .+.......t...... backtrace: [] __kmem_cache_alloc_node+0x1e4/0x2d8 [] kmalloc_trace+0x48/0x110 [] ath10k_wmi_tlv_op_gen_mgmt_tx_send+0xd4/0x1d8 [ath10k_core] [] ath10k_mgmt_over_wmi_tx_work+0x134/0x298 [ath10k_core] [] process_scheduled_works+0x1ac/0x400 [] worker_thread+0x208/0x328 [] kthread+0x100/0x1c0 [] ret_from_fork+0x10/0x20 Free the memory during completion and cleanup to fix the leak.
