MIPS: Don't crash in stack_top() for tasks without ABI or vDSO

...

SUSE CVE-2025-38696

In the Linux kernel, the following vulnerability has been resolved: MIPS: Don't crash in stacktop for tasks without ABI or vDSO Not all tasks have an ABI associated or vDSO mapped, for example kthreads never do. If such a task ever ends up calling stacktop, it will derefence the NULL ABI pointer...

SUSE CVE-2009-4271

The Linux kernel 2.6.9 through 2.6.17 on the x8664 and amd64 platforms allows local users to cause a denial of service panic via a 32-bit application that calls mprotect on its Virtual Dynamic Shared Object VDSO page and then triggers a segmentation fault...

kernel: ASLR bruteforce possible for vdso library

An information leak flaw was found in the way the Linux kernel's Virtual Dynamic Shared Object vDSO implementation performed address randomization. A local, unprivileged user could use this flaw to leak kernel memory addresses to user-space...

UBUNTU-CVE-2014-9585

The vdsoaddr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD...

kernel: missing boundary checks in syscall/syscall32_nopage()

arch/i386/kernel/sysenter.c in the Virtual Dynamic Shared Objects vDSO implementation in the Linux kernel before 2.6.21 does not properly check boundaries, which allows local users to gain privileges or cause a denial of service via unspecified vectors, related to the installspecialmapping,...
