 schedule+0x4c/0x190 BUG: spinlock recursion on CPU#0, ifconfig/2420 lock: terminate_lock.2+0x0/0x1c,
 .magic: dead4ead, .owner: ifconfig/2420, .owner_cpu: 0 While creating the stack trace, the unwinder uses
 the stack pointer to guess the previous frame to read the previous stack pointer from memory. The crash
 happens, because the unwinder tries to read from unaligned memory and as such triggers the unalignment
 trap handler which then leads to the spinlock recursion and finally to a deadlock. Fix it by checking the
 alignment before accessing the memory. (CVE-2025-68322)

Solution

Update the linux library and its related packages to version 6.12.63-1 or later.
