In the Linux kernel, the following vulnerability has been resolved: serial: max3100: Lock port->lock when calling uart_handle_cts_change() uart_handle_cts_change() has to be called with port lock taken, Since we run it in a separate work, the lock may not be taken at the time of running. Make sure that it's taken by explicitly doing that. Without it we got a splat: WARNING: CPU: 0 PID: 10 at drivers/tty/serial/serial_core.c:3491 uart_handle_cts_change+0xa6/0xb0 ...

https://notcve.org/view.php?id=CVE-2024-38633
In the Linux kernel, the following vulnerability has been resolved: serial: max3100: Update uart_driver_registered on driver removal The removal of the last MAX3100 device triggers the removal of the driver. However, code doesn't update the respective global variable and after insmod — rmmod — insmod cycle the kernel oopses: max3100 spi-PRP0001:01: max3100_probe: adding port 0 BUG: kernel NULL pointer dereference, address: 0000000000000408 ...

Hugo also noticed, that the error path in the probe also affected by having the variable set, and not cleared. Instead of clearing it move the assignment after the successfull uart_register_driver() call. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: serial: max3100: actualización uart_driver_registered al eliminar el controlador La eliminación del último dispositivo MAX3100 desencadena la eliminación del controlador.

In the Linux kernel, the following vulnerability has been resolved: watchdog: cpu5wdt.c: Fix use-after-free bug caused by cpu5wdt_trigger When the cpu5wdt module is removing, the origin code uses del_timer() to de-activate the timer. If the timer handler is running, del_timer() could not stop it and will return directly. If the port region is released by release_region() and then the timer handler cpu5wdt_trigger() calls outb() to write into the region that is released, the use-after-free bug will happen. Change del_timer() to timer_shutdown_sync() in order that the timer handler could be finished before the port region is released. • https://git.kernel.org/stable/c/e09d9c3e9f85b8190ca1e495890f4cf5ee30baf6 https://git.kernel.org/stable/c/9b1c063ffc075abf56f63e55d70b9778ff534314 https://git.kernel.org/stable/c/f19686d616500cd0d47b30cee82392b53f7f784a https://git.kernel.org/stable/c/573601521277119f2e2ba5f28ae6e87fc594f4d4 •

https://notcve.org/view.php?id=CVE-2024-38621
In the Linux kernel, the following vulnerability has been resolved: media: stk1160: fix bounds checking in stk1160_copy_video() The subtract in this condition is reversed. The ->length is the length of the buffer. The ->bytesused is how many bytes we have copied thus far. When the condition is reversed that means the result of the subtraction is always negative but since it's unsigned then the result is a very high positive value. That means the overflow check is never true. Additionally, the ->bytesused doesn't actually work for this purpose because we're not writing to "buf->mem + buf->bytesused". • https://git.kernel.org/stable/c/9cb2173e6ea8f2948bd1367c93083a2500fcf08f https://git.kernel.org/stable/c/f6a392266276730bea893b55d12940e32a25f56a https://git.kernel.org/stable/c/ecf4ddc3aee8ade504c4d36b7b4053ce6093e200 https://git.kernel.org/stable/c/a16775828aaed1c54ff4e6fe83e8e4d5c6a50cb7 https://git.kernel.org/stable/c/7532bcec0797adfa08791301c3bcae14141db3bd https://git.kernel.org/stable/c/b504518a397059e1d55c521ba0ea2b545a6c4b52 https://git.kernel.org/stable/c/d410017a7181cb55e4a5c810b32b75e4416c6808 https://git.kernel.org/stable/c/a08492832cc4cacc24e0612f483c86ca8 •
