CVE-2022-49387 watchdog: rzg2l_wdt: Fix 32bit overflow issue

In the Linux kernel, the following vulnerability has been resolved: watchdog: rzg2lwdt: Fix 32bit overflow issue The value of timercycleus can be 0 due to 32bit overflow. For eg:- If we assign the counter value "0xfff" for computing maxval. This patch fixes this issue by appending ULL to 1024, so...

CVE-2022-49387

CVE-2022-49387 concerns the Linux kernel watchdog driver rzg2l_wdt. The root cause is a 32-bit overflow in timer_cycle_us that can yield 0, e.g., when a counter like 0xfff is used to compute maxval. The provided connected documents confirm a patch that promotes values to 64-bit by appending ULL t...

CVE-2022-49379

In CVE-2022-49379, the Linux kernel suffers a regression in driver core wait_for_device_probe() interaction with deferred_probe_timeout, causing NFS rootfs mounting to time out when deferred_probe_timeout is non-zero. The root cause was that ip_auto_config() waited for current deferred probes, bu...
