26 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: serial: core: check uartclk for zero to avoid divide by zero Calling ioctl TIOCSSERIAL with an invalid baud_base can result in uartclk being zero, which will result in a divide by zero error in uart_get_divisor(). The check for uartclk being zero in uart_set_info() needs to be done before other settings are made as subsequent calls to ioctl TIOCSSERIAL for the same port would be impacted if the uartclk check was done where uartclk gets set.... • https://git.kernel.org/stable/c/3bbd90fca824e6fd61fb20f6dd2b0fa5f8b14bba •

23 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: usb: vhci-hcd: Do not drop references before new references are gained At a few places the driver carries stale pointers to references that can still be used. Make sure that does not happen. This strictly speaking closes ZDI-CAN-22273, though there may be similar races in the driver.

CVE-2022-48938 – CDC-NCM: avoid overflow in sanity checking
https://notcve.org/view.php?id=CVE-2022-48938
22 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: CDC-NCM: avoid overflow in sanity checking A broken device may give an extreme offset like 0xFFF0 and a reasonable length for a fragment. In the sanity check as formulated now, this will create an integer overflow, defeating the sanity check. Both offset and offset + len need to be checked in such a manner that no overflow can occur. And those quantities should be unsigned. In the Linux kernel, the following vulnerability has been resolved:... • https://git.kernel.org/stable/c/a612395c7631918e0e10ea48b9ce5ab4340f26a6 •

22 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: prevent copying too big compressed lzo segment Compressed length can be corrupted to be a lot larger than memory we have allocated for buffer. This will cause memcpy in copy_compressed_segment to write outside of allocated memory.
