CVE-2021-46976

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix crash in autoretire The retire logic uses the 2 lower bits of the pointer to the retire function to store flags. However, the autoretire function is not guaranteed to be aligned to a multiple of 4, which causes...

kernel: x86/sev: Make enc_dec_hypercall() accept a size instead of npages

In the Linux kernel, the following vulnerability has been resolved: x86/sev: Make encdechypercall accept a size instead of npages encdechypercall accepted a page count instead of a size, which forced its callers to round up. As a result, non-page aligned vaddrs caused pages to be spuriously marke...

crossbeam-utils Unsoundness of AtomicCell<{i,u}64> arithmetics on 32-bit targets that support Atomic{I,U}64

Impact The affected versions of this crate incorrectly assumed that the alignment of i,u64 was always the same as AtomicI,U64. However, the alignment of i,u64 on a 32-bit target can be smaller than AtomicI,U64. This can cause the following problems: - Unaligned memory accesses - Data race Crates...
