https://notcve.org/view.php?id=CVE-2021-47170
25 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: USB: usbfs: Don't WARN about excessively large memory allocations Syzbot found that the kernel generates a WARNing if the user tries to submit a bulk transfer through usbfs with a buffer that is way too large. This isn't a bug in the kernel; it's merely an invalid request from the user and the usbfs code does handle it correctly. In theory the same thing can happen with async transfers, or with the packet descriptor table for isochronous tr... • https://git.kernel.org/stable/c/2ab21d6e1411999b5fb43434f421f00bf50002eb •

25 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: serial: rp2: use 'request_firmware' instead of 'request_firmware_nowait' In 'rp2_probe', the driver registers 'rp2_uart_interrupt' then calls 'rp2_fw_cb' through 'request_firmware_nowait'. In 'rp2_fw_cb', if the firmware don't exists, function just return without initializing ports of 'rp2_card'. But now the interrupt handler function has been registered, and when an interrupt comes, 'rp2_uart_interrupt' may access those ports then causing ... • https://git.kernel.org/stable/c/1e04d5d5fe5e76af68f834e1941fcbfa439653be •

25 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Don't generate an interrupt on bus reset Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt handler (i801_isr) is not prepared for this situation and will try to process the interrupt as if it was signaling the end of a successful transaction.
