In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Fix RX consumer index logic in the error path.

In bnxt_rx_pkt(), the RX buffers are expected to complete in order. If the RX consumer index indicates an out of order buffer completion, it means we are hitting a hardware bug and the driver will abort all remaining RX packets and reset the RX ring. The RX consumer index that we pass to bnxt_discard_rx() is not correct. We should be passing the current index (tmp_raw_cons) instead of the old index (raw_cons). This bug can cause us to be at the wrong index when trying to abort the next RX packet. It can crash like this:

OESA-2024-1345 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel, the following vulnerability has been resolved: i2c: xiic: fix reference leak when pm_runtime_get_sync fails The PM reference count is not expected to be incremented on return in xiic_xfer and xiic_i2c_remove. However, pm_runtime_get_sync will increment the PM reference count even failed. Forgetting to putting operation will result in a reference leak here. Replace it with pm_runtime_resume_and_get to keep usage counter balanced.(CVE-2020-36778) In the Linux kernel, the following vulnerability has been resolved: i2c: imx-lpi2c: fix reference leak when pm_runtime_get_sync fails The PM reference count is not expected to be incremented on return in lpi2c_imx_master_enable. However, pm_runtime_get_sync will increment the PM reference count even failed. Forgetting to putting operation will result in a reference leak here. Replace it with pm_runtime_resume_and_get to keep usage counter balanced.(CVE-2020-36782) In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fix info leak in hid_submit_ctrl In hid_submit_ctrl(), the way of calculating the report length doesn't take into account that report->size can be zero. When running the syzkaller reproducer, a report of size 0 causes hid_submit_ctrl) to calculate transfer_buffer_length as 16384. When this urb is passed to the usb core layer, KMSAN reports an info leak of 1…
