This patch fixes this by utilizing the open_how struct that we store while in the audit_context with audit_openat2_how(). Independent of this patch, Richard dude Briggs posted an analogous patch on the audit mailing record approximately 40 minutes right after this patch was posted.
from the Linux kernel, the subsequent vulnerability has been settled: mtd: parsers: qcom: Fix lacking cost-free for pparts in cleanup Mtdpart isn't going to absolutely free pparts every time a cleanup perform is declared. include lacking absolutely free for pparts in cleanup purpose for smem to repair the leak.
previous to commit 45bf39f8df7f ("USB: core: Do not keep gadget lock whilst looking at the "descriptors" sysfs file") this race couldn't manifest, because the routines ended up mutually unique because of the machine locking. getting rid of that locking from read_descriptors() uncovered it to your race. The simplest way to take care of the bug is to keep hub_port_init() from shifting udev->descriptor after udev has long been initialized and registered. Drivers assume the descriptors stored from the kernel to become immutable; we must not undermine this expectation. in truth, this variation must have been made long ago. So now hub_port_init() will consider an additional argument, specifying a buffer in which to store the unit descriptor it reads. (If udev has not nonetheless been initialized, the buffer pointer will likely be NULL and after that hub_port_init() will store the product descriptor in udev as before.) This gets rid of the information race liable for the out-of-bounds read. The improvements to hub_port_init() look extra substantial than they really are, on account of indentation changes ensuing from an make an effort to stay clear of producing to other portions of the usb_device composition soon after it's been initialized. comparable alterations should be built on the code that reads the BOS descriptor, but that may be managed in the separate patch afterwards. This patch is enough to repair the bug uncovered by syzbot.

The WP Mail SMTP plugin for WordPress is susceptible to information exposure in all versions nearly, and including, 4.0.1. This is due to plugin here providing the SMTP password during the SMTP Password subject when viewing the configurations. This makes it attainable for authenticated attackers, with administrative-stage entry and over, to look at the SMTP password for that provided server.

from the Linux kernel, the subsequent vulnerability is settled: mm: Never endeavor to NUMA-migrate COW internet pages that have other uses Oded Gabbay reports that enabling NUMA balancing triggers corruption with his Gaudi accelerator take a look at load: "All the small print are while in the bug, but The underside line is the fact somehow, this patch leads to corruption if the numa balancing attribute is enabled AND we do not use process affinity AND we use GUP to pin internet pages so our accelerator can DMA to/from method memory. both disabling numa balancing, applying process affinity to bind to precise numa-node or reverting this patch triggers the bug to disappear" and Oded bisected the issue to dedicate 09854ba94c6a ("mm: do_wp_page() simplification"). Now, the NUMA balancing shouldn't actually be altering the writability of the website page, and as a result should not subject for COW. nonetheless it seems it does. Suspicious. having said that, no matter that, the affliction for enabling NUMA faults in change_pte_range() is nonsensical.

- A packet SKB might be constructed whose tail is much outside of its conclude, causing out-of-bounds heap knowledge to be viewed as Portion of the SKB's knowledge. I have examined that This may be used by a destructive USB gadget to deliver a bogus ICMPv6 Echo ask for and acquire an ICMPv6 Echo Reply in response which contains random kernel heap information. It can be in all probability also achievable for getting OOB writes from this on somewhat-endian technique someway - perhaps by triggering skb_cow() by way of IP options processing -, but I haven't analyzed that.
