https://notcve.org/view.php?id=CVE-2022-49027
In the Linux kernel, the following vulnerability has been resolved: iavf: Fix error handling in iavf_init_module() The iavf_init_module() won't destroy workqueue when pci_register_driver() failed. Call destroy_workqueue() when pci_register_driver() failed to prevent the resource leak. Similar to the handling of u132_hcd_init in commit f276e002793c ("usb: u132-hcd: fix resource leak") • https://git.kernel.org/stable/c/2803b16c10ea7eec170c485388f5f26ae30e92fe https://git.kernel.org/stable/c/971c55f0763b480e63ceb7a22beb19be2509e5ed https://git.kernel.org/stable/c/0d9f5bd54b913018031c5b964fc1f9a31f5f6cb5 https://git.kernel.org/stable/c/bd477b891a4fa084561234eed4afacb3001dd359 https://git.kernel.org/stable/c/227d8d2f7f2278b8468c5531b0cd0f2a905b4486 •

https://notcve.org/view.php?id=CVE-2022-49026
In the Linux kernel, the following vulnerability has been resolved: e100: Fix possible use after free in e100_xmit_prepare In e100_xmit_prepare(), if we can't map the skb, then return -ENOMEM, so e100_xmit_frame() will return NETDEV_TX_BUSY and the upper layer will resend the skb. But the skb is already freed, which will cause UAF bug when the upper layer resends the skb. Remove the harmful free. • https://git.kernel.org/stable/c/5e5d49422dfb035ca9e280cd61d434095c151272 https://git.kernel.org/stable/c/b775f37d943966f6f77dca402f5a9dedce502c25 https://git.kernel.org/stable/c/9fc27d22cdb9b1fcd754599d216a8992fed280cd https://git.kernel.org/stable/c/b46f6144ab89d3d757ead940759c505091626a7d https://git.kernel.org/stable/c/45605c75c52c7ae7bfe902214343aabcfe5ba0ff •

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix use-after-free when reverting termination table When having multiple dests with termination tables and second one or afterwards fails the driver reverts usage of term tables but doesn't reset the assignment in attr->dests[num_vport_dests].termtbl which case a use-after-free when releasing the rule.

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: fix buffer overflow in elem comparison For vendor elements, the code here assumes that 5 octets are present without checking. Since the element itself is already checked to fit, we only need to check the length. • https://git.kernel.org/stable/c/0b8fb8235be8be99a197e8d948fc0a2df8dc261a https://git.kernel.org/stable/c/f5c2ec288a865dbe3706b09bed12302e9f6d696b https://git.kernel.org/stable/c/9e6b79a3cd17620d467311b30d56f2648f6880aa https://git.kernel.org/stable/c/88a6fe3707888bd1893e9741157a7035c4159ab6 https://git.kernel.org/stable/c/391cb872553627bdcf236c03ee7d5adb275e37e1 https://git.kernel.org/stable/c/9f16b5c82a025cd4c864737409234ddc44fb166a •
