CVE-2023-53474

CVE-2023-53474 affects the Linux kernel’s AMD/Intel x86 Machine Check Architecture (MCA) handling. Root cause: bank_map was an unsigned int, causing shift-out-of-bounds when bank indices reached 32, triggering UBSAN. Resolution: changed bank_map to a 64-bit type and used BIT_ULL() for bit operati...

CVE-2022-50425 x86/fpu: Fix copy_xstate_to_uabi() to copy init states correctly

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Fix copyxstatetouabi to copy init states correctly When an extended state component is not present in fpstate, but in init state, the function copies from initfpstate via copyfeature. But, dynamic states are not present ...

CVE-2023-23626

go-bitfield is a simple bitfield package for the go language aiming to be more performant that the standard library. When feeding untrusted user input into the size parameter of NewBitfield and FromBytes functions, an attacker can trigger panics. This happen when the size is a not a multiple of 8...

The vulnerability of the BPF_CORE_READ_BITFIELD macro definition of the bpf component in the Linux operating system’s kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the BPFCOREREADBITFIELD macro definition in the tools/lib/bpf/bpfcoreread.h file of the Linux kernel’s bpf component is related to the absence of initialization for variables. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity,...
