https://notcve.org/view.php?id=CVE-2024-50296
In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix kernel crash when uninstalling driver When the driver is uninstalled and the VF is disabled concurrently, a kernel crash occurs. The reason is that the two actions call function pci_disable_sriov(). The num_VFs is checked to determine whether to release the corresponding resources. During the second calling, num_VFs is not 0 and the resource release function is called. However, the corresponding resource has been released during the first invoking. Therefore, the problem occurs: [15277.839633][T50670] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 ...

In the Linux kernel, the following vulnerability has been resolved: media: v4l2-tpg: prevent the risk of a division by zero As reported by Coverity, the logic at tpg_precalculate_line() blindly rescales the buffer even when scaled_witdh is equal to zero. If this ever happens, this will cause a division by zero. Instead, add a WARN_ON_ONCE() to trigger such cases and return without doing any precalculation. • https://git.kernel.org/stable/c/63881df94d3ecbb0deafa0b77da62ff2f32961c4 https://git.kernel.org/stable/c/e3c36d0bde309f690ed1f9cd5f7e63b3a513f94a https://git.kernel.org/stable/c/0bfc6e38ee2250f0503d96f1a1de441c31d88715 https://git.kernel.org/stable/c/054931ca3cfcb8e8fa036e887d6f379942b02565 https://git.kernel.org/stable/c/a749c15dccc58d9cbad9cd23bd8ab4b5fa96cf47 https://git.kernel.org/stable/c/c63c30c9d9f2c8de34b16cd2b8400240533b914e https://git.kernel.org/stable/c/2d0f01aa602fd15a805771bdf3f4d9a9b4df7f47 https://git.kernel.org/stable/c/0cdb42ba0b28f548c1a4e86bb8489dba0 •
