    crypto: cavium - prevent integer overflow loading firmware

    In the Linux kernel, the following vulnerability has been resolved: crypto: cavium - prevent integer overflow loading firmware The "code_length" value comes from the firmware file. If your firmware is untrusted realistically there is probably very little you can do to protect yourself. Still we try to limit the damage as much as possible. Also Smatch marks any data read from the filesystem as untrusted and prints warnings if it not capped correctly. The "ntohl(ucode->code_length) * 2" multiplication can have an integer overflow.

    In the Linux kernel, the following vulnerability has been resolved: net: do not sense pfmemalloc status in skb_append_pagefrags() skb_append_pagefrags() is used by af_unix and udp sendpage() implementation so far. In commit 326140063946 ("tcp: TX zerocopy should not sense pfmemalloc status") we explained why we should not sense pfmemalloc status for pages owned by user space. We should also use skb_fill_page_desc_noacc() in skb_append_pagefrags() to avoid following KCSAN report: BUG: KCSAN: data-race in lru_add_fn / skb_append_pagefrags write to 0xffffea00058fc1c8 of 8 bytes by task 17319 on cpu 0: __list_add include/linux/list.h:73 [in

    In the Linux kernel, the following vulnerability has been resolved: ACPI: tables: FPDT: Don't call acpi_os_map_memory() on invalid phys address On a Packard Bell Dot SC (Intel Atom N2600 model) there is a FPDT table which contains invalid physical addresses, with high bits set which fall outside the range of the CPU-s supported physical address range. Calling acpi_os_map_memory() on such an invalid phys address leads to the below WARN_ON in ioremap triggering resulting in an oops/stacktrace. Add code to verify the physical address before calling acpi_os_map_memory() to fix / avoid the oops. [ 1.226900] ioremap: invalid physical addres

    In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox() pci_get_device() will increase the reference count for the returned 'dev'. We need to call pci_dev_put() to decrease the reference count. Since 'dev' is only used in pci_read_config_dword(), let's add pci_dev_put() right after it.

    firmware: arm_ffa: Fix FFA device names for logical partitions

    In the Linux kernel, the following vulnerability has been resolved: firmware: arm_ffa: Fix FFA device names for logical partitions Each physical partition can provide multiple services each with UUID. Each such service can be presented as logical partition with a unique combination of VM ID and UUID. The number of distinct UUID in a system will be less than or equal to the number of logical partitions. However, currently it fails to register more than one logical partition or service within a physical partition as the device name contains only VM ID while both VM ID and UUID are maintained in the partition information. The kernel complains
