CVE-2023-53506

In the Linux kernel, the following vulnerability has been resolved: udf: Do not bother merging very long extents When merging very long extents we try to push as much length as possible to the first extent. However this is unnecessarily complicated and not really worth the trouble. Furthermore there was a bug in the logic resulting in corrupting extents in the file as syzbot reproducer shows. So just don't bother with the merging of extents that are too long together.

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

md: Replace snprintf with scnprintf

Current code produces a warning as shown below when total characters in the constituent block device names plus the slashes exceeds 200. snprintf() returns the number of characters generated from the given input, which could cause the expression “200 – len” to wrap around to a large positive number. Fix this by using scnprintf() instead, which returns the actual number of characters written into the buffer.

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

nbd: Fix hung when signal interrupts nbd_start_device_ioctl()

syzbot reported hung task [1]. The following program is a simplified version of the reproducer:

int main(void) { int sv[2], fd;

if (socketpair(AF_UNIX, SOCK_STREAM, 0, sv) < 0)
	return 1;
if ((fd = open("/dev/nbd0", 0)) < 0)
	return 1;
if (ioctl(fd, NBD_SET_SIZE_BLOCKS, 0x81) < 0)
	return 1;
if (ioctl(fd, NBD_SET_SOCK, sv[0]) < 0)
	return 1;
if (ioctl(fd, NBD_DO_IT) < 0)
	return 1;
return 0;

}

When signal interrupt nbd_start_device_ioctl() waiting the condition atomic_read(&config->recv_threads) == 0, the task can hung because it waits the completion of the inflight IOs.

This patch fixes the issue by clearing queue, not just shutdown, when signal interrupt nbd_start_device_ioctl().(CVE-2022-50314)
