Vulnerability Details CVE-2024-26618
In the Linux kernel, the following vulnerability has been resolved:
arm64/sme: Always exit sme_alloc() early with existing storage
When sme_alloc() is called with existing storage and we are not flushing we
will always allocate new storage, both leaking the existing storage and
corrupting the state. Fix this by separating the checks for flushing and
for existing storage as we do for SVE.
Callers that reallocate (eg, due to changing the vector length) should
call sme_free() themselves.
