CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HIn the Linux kernel, the following vulnerability has been resolved: idpf: fix memory leak in idpf_vport_rel() Free vport->rx_ptype_lkup in idpf_vport_rel() to avoid leaking memory during a reset. Reported by kmemleak: unreferenced object 0xff450acac838a000 (size 4096): comm "kworker/u258:5", pid 7732, jiffies 4296830044 hex dump (first 32 bytes): 00 00 00 00 00 10 00 00 00 10 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 10 00 00 00 00 00 00 ................ backtrace (crc 3da81902): __kmalloc_cache_noprof+0x469/0x7a0 idpf_send_get_rx_ptype_msg+0x90/0x570 [idpf] idpf_init_task+0x1ec/0x8d0 [idpf] process_one_work+0x226/0x6d0 worker_thread+0x19e/0x340 kthread+0x10f/0x250 ret_from_fork+0x251/0x2b0 ret_from_fork_asm+0x1a/0x30 A flaw was found in the Linux kernel's idpf driver. This memory leak occurs because the `idpf_vport_rel()` function fails to free allocated memory during a reset operation. A local attacker could exploit this vulnerability to exhaust system memory, leading to a denial of service (DoS).
