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...

Quarkus Security Vulnerabilities

Quarkus is a cloud-native Linux container-first framework for writing Java applications. A security vulnerability exists in Quarkus that stems from one of the HTTP security policies failing to properly clean up certain character alignments when accepting a request, resulting in incorrect privileg...

Crypto++ buffer error vulnerability

Crypto++ is a C++ cryptographic method library. A security vulnerability exists in Crypto++ 8.4 and earlier versions, which stems from the fact that if allocated memory is not 16-byte aligned, the function FixSizeAllocatorWithCleanup may write to memory outside of the allocation...
