CVE-2018-1000199

CVE-2018-1000199 Linux ptrace 代码对调试寄存器 debug registers 的访问进行了虚拟化，而这段虚拟化代码存在错误的错误处理。这意味着，如果你向 DR0 等寄存器写入非法值，内核断点跟踪的内部状态可能变得损坏，尽管 ptrace 调用会返回 -EINVAL。 例如，你可以在 x86 内核的 /proc/kallsyms 中找到 dodebug 的地址，然后将该地址传给附带的 PoC。我怀疑除 x86 之外的其他架构也可能受影响，但我尚未尝试利用此漏洞。该漏洞本身广泛分布于内核的通用代码和架构代码中。...

LoongBleed

LoongBleed English LoongBleed 是一种硬件漏洞，概念上类似于 ZenBleed CVE-2023-20593，影响同时实现了 LSX（128 位 SIMD）和 LASX（256 位 SIMD）的龙芯 LA464/LA664 处理器。 在 LoongArch 架构中，LSX $vr 寄存器（128 位）与 LASX $xr 寄存器（256 位）的低 128 位重叠。LSX 指令和基础浮点操作在架构上只应操作低 128 位（或其子集）；对应 $xr 寄存器的高位应当保持不变。然而，由于微架构缺陷，这些操作可能通过 $xr 的高 128 位泄露数据...

CVE-2026-98034

The Linux kernel contains a vulnerability where the BPF verifier fails to mark a register as precise when it is known to contain zero during a scalar store into an untrusted kptr field. Because check_map_kptr_access() does not mark the register as precise, a state checkpoint with an imprecise zer...

kernel: drm/xe/rtp: Add RING_FORCE_TO_NONPRIV_DENY to OA whitelists

A flaw was found in the drm/xe/rtp component of the Linux kernel. This vulnerability arises from the unconditional whitelisting of Output/Availability OA registers, which is a security violation. By default, these registers could be whitelisted after system events such as probe, graphics...
