CVE-2023-53051
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
dm crypt: add cond_resched() to dmcrypt_write()
The loop in dmcrypt_write may be running for unbounded amount of time, thus we need cond_resched() in it.
This commit fixes the following warning:
