https://notcve.org/view.php?id=CVE-2022-49013
In the Linux kernel, the following vulnerability has been resolved: sctp: fix memory leak in sctp_stream_outq_migrate() When sctp_stream_outq_migrate() is called to release stream out resources, the memory pointed to by prio_head in stream out is not released. The memory leak information is as follows: unreferenced object 0xffff88801fe79f80 (size 64): comm "sctp_repo", pid 7957, jiffies 4294951704 (age 36.480s) hex dump (first 32 bytes): 80 9f e7 1f 80 88 ff ff 80 9f e7 1f 80 88 ff ff ................ 90 9f e7 1f 80 88 ff ff 90 9f e7 1f 80 88 ff ff ................ backtrace: [<ffffffff81b215c6>] kmalloc_trace+0x26/0x60 [<ffffffff88ae517c>] sctp_sched_prio_set+0x4cc/0x770 [<ffffffff88ad64f2>] sctp_stream_init_ext+0xd2/0x1b0 [<ffffffff88aa2604>] sctp_sendmsg_to_asoc+0x1614/0x1a30 [<ffffffff88ab7ff1>] sctp_sendmsg+0xda1/0x1ef0 [<ffffffff87f765ed>] inet_sendmsg+0x9d/0xe0 [<ffffffff8754b5b3>] sock_sendmsg+0xd3/0x120 [<ffffffff8755446a>] __sys_sendto+0x23a/0x340 [<ffffffff87554651>] __x64_sys_sendto+0xe1/0x1b0 [<ffffffff89978b49>] do_syscall_64+0x39/0xb0 [<ffffffff89a0008b>] entry_SYSCALL_64_after_hwframe+0x63/0xcd • https://git.kernel.org/stable/c/637784ade221a3c8a7ecd0f583eddd95d6276b9a https://git.kernel.org/stable/c/a7555681e50bdebed2c40ff7404ee73c2e932993 https://git.kernel.org/stable/c/176ee6c673ccd118e9392fd2dbb165423bdb99ca https://git.kernel.org/stable/c/0dfb9a566327182387c90100ea54d8426cee8c67 https://git.kernel.org/stable/c/fa20f88271259d42ebe66f0a8c4c20199e888c99 https://git.kernel.org/stable/c/9ed7bfc79542119ac0a9e1ce8a2a5285e43433e9 •

https://notcve.org/view.php?id=CVE-2022-49011
In the Linux kernel, the following vulnerability has been resolved: hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new() As comment of pci_get_domain_bus_and_slot() says, it returns a pci device with refcount increment, when finish using it, the caller must decrement the reference count by calling pci_dev_put(). So call it after using to avoid refcount leak. • https://git.kernel.org/stable/c/14513ee696a0cd12a19318e433b75a786808adc3 https://git.kernel.org/stable/c/bb75a0d1223d43f97089841aecb28a9b4de687a9 https://git.kernel.org/stable/c/0dd1da5a15eeecb2fe4cf131b3216fb455af783c https://git.kernel.org/stable/c/2f74cffc7c85f770b1b1833dccb03b8cde3be102 https://git.kernel.org/stable/c/ea5844f946b1ec5c0b7c115cd7684f34fd48021b https://git.kernel.org/stable/c/c40db1e5f316792b557d2be37e447c20d9ac4635 https://git.kernel.org/stable/c/6e035d5a2a6b907cfce9a80c5f442c2e459cd34e https://git.kernel.org/stable/c/f598da27acbeee414679cacd14294db3e •
