kernel: Linux kernel: Use-after-free in device mapper due to race condition in zone reporting

A flaw was found in the Linux kernel's device mapper dm component. When setting up zone append emulation resources, a race condition can occur if the blkrevalidatediskzones function fails while another process simultaneously calls dmblkreportzones. This timing issue can lead to a use-after-free...

AZL-64595 CVE-2025-38140 affecting package kernel 6.6.126.1-1

In the Linux kernel, the following vulnerability has been resolved: dm: limit swapping tables for devices with zone write plugs dmrevalidatezones only allowed new or previously unzoned devices to call blkrevalidatediskzones. If the device was already zoned, disk-nrzones would always equal...

DEBIAN-CVE-2025-38141

In the Linux kernel, the following vulnerability has been resolved: dm: fix dmblkreportzones If dmgetlivetable returned NULL, dmputlivetable was never called. Also, it is possible that md-zonerevalidatemap will change while calling this function. Only read it once, so that we are always using the...
