CVE-2023-53474

In CVE-2023-53474, the Linux kernel’s x86 MCE AMD code fixed an overflow in bank_map by switching from unsigned int to u64 and using BIT_ULL when manipulating bits. The MCA bank count is 64 (MAX_NR_BANKS), and the previous 32-bit bank_map could shift past 32, triggering UBSAN shift-out-of-bounds....

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,...
