 00 00 00 00 00 00 00 00 00 00 00 00 00 This issue seems to be related to the behavior of some gcc
 compilers and was also fixed on the s390 architecture before: commit d93a855c31b7 ("s390/ptrace: Avoid
 KASAN false positives in regs_get_kernel_stack_nth()") As described in that commit,
 regs_get_kernel_stack_nth() has confirmed that `addr` is on the stack, so reading the value at `*addr`
 should be allowed. Use READ_ONCE_NOCHECK() helper to silence the KASAN check for this case. [will: Use
 '*addr' as the argument to READ_ONCE_NOCHECK()] (CVE-2025-38320)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
