Description

In the Linux kernel, the following vulnerability has been resolved: via_wdt: fix critical boot hang due to unnamed resource allocation The VIA watchdog driver uses allocate_resource() to reserve a MMIO region for the watchdog control register. However, the allocated resource was not given a name, which causes the kernel resource tree to contain an entry marked as "<BAD>" under /proc/iomem on x86 platforms. During boot, this unnamed resource can lead to a critical hang because subsequent resource lookups and conflict checks fail to handle the invalid entry properly.

Affected configurations

• linux linux kernel (>= 3.3.1 < 5.10.248) • linux linux kernel (>= 5.11 < 5.15.198) • linux linux kernel (>= 5.16 < 6.1.160) • linux linux kernel (>= 6.2 < 6.6.120) • linux linux kernel (>= 6.7 < 6.12.64) • linux linux kernel (>= 6.13 < 6.18.3) • linux linux kernel 3.3 • linux linux kernel 6.19
